Nevertheless, not all visitor stars are created equal, with a number of standing as clear highlights of their respective episodes. Whether or not it is one-and-done appearances or casual recurring roles, efficient visitor stars rapidly are embraced as fan-favorites. In reality, some join with the forged, crew, and viewers so properly, they’ve inadvertently steered the course of the franchise.
An ideal visitor star gels seamlessly with the primary forged and naturally elevates the story that they are showing in. Relatively than merely feeling like stunt casting, a visitor position appears like an natural addition to the Star Trek franchise. For the needs of this text, stars showing on this checklist don’t embrace actors who’ve appeared as collection regulars on different Star Trek exhibits. Listed here are the 15 finest visitor stars on Star Trek, ranked in descending order.
Stephen Hawking
Star Trek has had a lot of fast cameos over time, together with non-actors taking part in bit components on numerous collection and films. “Star Trek: The Subsequent Technology,” specifically, had a number of actors and popular culture figures seem all through its seven-season run, amusingly together with Fleetwood Mac drummer Mick Fleetwood as a fish alien. Famed astrophysicist Stephen Hawking went one step additional for his cameo on “Star Trek: The Subsequent Technology,” showing on the Season 6 finale “Descent, Half I.” Relatively than play a fictional character, Hawking, a significant Star Trek fan, plays a facsimile of himself.
“TNG” recurrently featured its principal characters taking part in poker collectively of their quarters between serving shifts on the bridge. To assist enhance his poker recreation, Information (Brent Spiner) packages holograms of Isaac Newton (John Neville), Albert Einstein (Jim Norton), and Hawking to hitch him for a pleasant recreation. Information’s reasoning is that he wish to research how the best scientific minds of all time work together with one another over the sport. To his amusement, Hawking fools Einstein into believing he was bluffing in between evaluating astronomical observations.
Stacey Abrams
The Star Trek franchise made its triumphant return to tv with the launch of “Star Trek: Discovery” in 2017. “Discovery” restored one thing that had been lacking from Star Trek for a while –- salient social commentary, typically chatting with modern points by the prism of science fiction. That is by no means extra obvious on the collection than the shock guest-starring look of politician and social activist Stacey Abrams on the Season 4 finale. Abrams performs the President of the United Earth, who formally broadcasts the planet is rejoining the United Federation after centuries of strained relations.
A lot of the latter half of “Discovery,” set over 900 years after the occasions of “TOS,” is about rebuilding hope after recovering from disaster. Abrams, in her personal real-life position with American electoral reform, offers a distinguished reminder that there’s nonetheless a lot work to do to construct a greater future. Nevertheless, simply as together with her Star Trek character, Abrams factors out that this work is supposed to be executed collectively as Earth takes its rightful place again within the Federation. Abrams, herself a fan of Star Trek, relished the chance to work with the forged and use the present as a platform to instill hope for a greater tomorrow.
John Colicos
Jim Kirk (William Shatner) has confronted loads of Klingons in his time captaining the Enterprise, however his very first Klingon opponent, Commander Kor (John Colicos), is among the many most memorable. Showing on the “Star Trek: The Authentic Collection” episode “Errand of Mercy,” Kor leads the Klingon occupation of the peaceable planet of Organia. As Kirk and Spock (Leonard Nimoy) mount a resistance in opposition to Kor and his military, the Klingons escalate their brutality in opposition to the Organians. With the Federation and Klingon Empire poised for an all-out warfare, the Organians reveal their true, omnipotent nature, forming an armistice to Kor’s seen disappointment.
Colicos offers “TOS” with one in all its most memorable villains, with Kor assembly each effort made in opposition to him in refined viciousness. There may be each a palpable animosity and begrudging respect shared between Kirk and Kor, serving to set up the Klingons as probably the most constant enemy on “TOS.” Almost 30 years later, Colicos reprised his position as Kor on “Star Trek: Deep Area 9,” taking part in an older, embittered model of the Klingon. Showing on three “DS9” episodes, Colicos cemented Kor’s place because the franchise’s final “TOS”-era Klingon.
Kelsey Grammer
By 1992, “The Subsequent Technology” reached the height of its broadcast reputation, averaging over 11 million viewers per episode. This coincided with Kelsey Grammer turning into a significant tv star, after a profitable run on “Cheers,” and getting ready to headline his personal spinoff collection, “Frasier,” the next yr. With each exhibits produced by Paramount, Grammer was supplied the prospect to visitor star on the “TNG” Season 5 episode, “Trigger and Impact.” A Star Trek fan himself, Grammer accepted, appearing as Morgan Bateson, captain of the time-displaced USS Bozeman.
“Trigger and Impact” is an episode revolving fully round unusual time-travel mechanics, with the Enterprise and Bozeman trapped in a recurring temporal loop. As such, the 2 starship crews continually discover themselves residing out the identical scenes, progressively noticing that one thing feels off in regards to the scenario. In lesser fingers, the episode might’ve felt like a repetitive slog, however the forged, together with Grammer, and director Jonathan Frakes pull off its execution brilliantly. Grammer, specifically, helps elevate the proceedings, making the confusion the affected crews are experiencing all of the extra palatable as they attempt to decide what precisely is happening.
Sonja Sohn
One of many inciting premises behind “Discovery” is the concept Sarek (James Frain) had an adoptive human daughter in Michael Burnham (Sonequa Martin-Inexperienced). The 2nd season of “Discovery” introduces Burnham’s mom, Physician Gabrielle Burnham (Sonja Sohn), displaced in house and time by a temporal anomaly. Gabrielle reunites together with her daughter within the thirty second century after each are flung into the far-future on the finish of Season 2. Shaken by her experiences, Gabrielle finally finds solace within the Ni’Var monastic order, the Qowat Milat.
It is simple to see the place Burnham will get her fiery depth each time she shares scenes with mom, with Sonja Sohn bringing the identical degree of fierce dedication as Inexperienced. There’s all the time lots happening below the floor for the Burnhams, from the misplaced years as mom and daughter to the galaxy-saving stakes at hand. By the third and 4th seasons, Sohn brings a softer vitality in her efficiency as Gabrielle, not scrambling by time to avoid wasting natural life. Parental dynamics have a particular high quality in Star Trek particularly, and Michael and Gabrielle’s is among the many most original and rewarding.
Roger C. Carmel
Harcourt Fenton Mudd (Roger C. Carmel) seems early on “The Authentic Collection,” debuting on the episode “Mudd’s Girls” as an interstellar prison. Carmel reprised his position within the 2nd season episode “I, Mudd,” giving his character a way more comedic method. Carmel’s ultimate efficiency as Mudd was on “Star Trek: The Animated Collection,” showing on the first season episode “Mudd’s Ardour.” Ever the trickster and conman, Mudd was offered extra as a nuisance for Kirk and the Enterprise relatively than a real menace.
Mudd is without doubt one of the few recurring characters on “TOS,” together with his second look really far more entertaining than his debut. Whereas Carmel initially performed Mudd like a conniving criminal, his return on “I, Mudd” makes him extra of a bumbling buffoon. This portrayal is much better suited to Carmel’s performing strengths and makes “I, Mudd” probably the most outright enjoyable, and funniest, episodes of the collection. Although Rainn Wilson does his finest taking part in Mudd on “Star Trek: Discovery,” it by no means fairly reaches the bar initially set by Carmel.
Mia Kirshner
Jane Wyatt memorably performed Spock’s mom Amanda Grayson on “The Authentic Collection” and in “Star Trek IV: The Voyage Dwelling,” reminding her son of his rejected humanity. Whereas different actors have performed Grayson since, no different actor meets, or arguably exceeds, Wyatt’s efficiency except Mia Kirshner. Kirshner performs Grayson on the primary two seasons of “Discovery,” offering steerage for Spock (Ethan Peck) and her adoptive daughter Burnham. Kirshner reprises her position as Grayson on “Star Trek: Unusual New Worlds,” serving to Spock with an engagement occasion whereas concealing that he has briefly been rendered absolutely human.
Kirshner brings a larger sense of heat and sympathy to Grayson than some other actor, together with Wyatt. Others had performed Grayson extra distantly, not in contrast to a Vulcan, regardless of Grayson embodying Spock’s human heritage. Beneath Kirshner, Grayson is subtly extra open and understanding of her youngsters, particularly as Spock faces extreme psychological instability on “Discovery” Season 2. Kirshner’s return for “Unusual New Worlds” provides her a enjoyable and comedic route to take her character, showcasing her comical chops as she helps Spock together with his resurgent humanity.
William Campbell
Earlier than Q, there was Trelane, the all-powerful delinquent performed by William Campbell on the “Authentic Collection” Season 1 episode “The Squire of Gothos.” Regardless of his reality-altering powers, Trelane is offered as an immature determine, infuriated by Kirk’s unwillingness to play his harmful video games. Campbell is a a lot completely different adversary for Kirk on the fan-favorite episode “The Bother with Tribbles,” taking part in Klingon officer Captain Koloth. Campbell reprised his position as Koloth years in a while “Deep Area 9,” dying honorably within the discipline of battle on the episode “Blood Oath.”
In lesser fingers, Trelane might’ve come off as a personality that might be simply as annoying to audiences as Kirk and the Enterprise. Beneath Campbell, the character is playful and mischievous, however fortuitously by no means grating to the viewers. As Koloth, Campbell presents a extra light-hearted Klingon antagonist for Kirk, becoming in with the episode’s extra comedic sensibilities. Campbell will get the prospect to flip this on its head on “DS9,” giving Koloth the ultimate blaze of glory that he so richly deserves.
Joan Collins
Captain Kirk has had loads of love pursuits on “The Authentic Collection” and subsequent depictions, however one which looms above the remainder is Edith Keeler. Performed by British actor Joan Collins, Keeler seems on the primary season episode “The Metropolis on the Fringe of Without end.” Keeler lives in 1930 New York Metropolis, the place she meets a time-traveling Kirk, Spock, and Physician McCoy (DeForest Kelley) after they journey. Regardless of the budding romance between Kirk and Keeler, he should permit her dying to happen to protect historical past and the Prime Timeline.
“The Metropolis on the Fringe of Without end” is broadly considered one of many greatest Star Trek episodes, and the episode solely works if we consider in Kirk’s love for Keeler. Fortuitously, Collins simply radiates heat and charm in her efficiency, making the viewers purchase that her character might inadvertently derail the timeline if she was allowed to outlive. There’s a deep tenderness to Keeler, not solely with how she interacts with Kirk, but in addition how she cares for a gravely sick McCoy. Collins does not simply give Star Trek Kirk’s finest love curiosity; she units a excessive bar for all visitor stars the franchise would see shifting ahead.
Dwayne Johnson
Earlier than he was one of many greatest film stars on this planet, an early performing position for Dwayne Johnson was on “Star Trek: Voyager.” Showing on the Season 6 episode “Tsunkatse,” Johnson performs a combined martial arts champion on a planet that the Voyager crew visits on shore go away. After Tuvok (Tim Russ) turns into injured and requires emergency medical consideration, Seven of 9 (Jeri Ryan) agrees to face the champion within the ring. Throughout his fights on the episode, Johnson not solely does all his personal stunts, however delivers a few of his signature WWE strikes, together with the Rock Backside.
Johnson’s Star Trek position was on the controversial peak of his skilled wrestling profession and a full yr earlier than his big-screen debut in “The Mummy Returns.” Johnson leans into a lot of his regular wrestling heel methods of the commerce, gamely grandstanding for the viewers with all of his star-making swagger. This position elevates “Tsunkatse” to be one in all most memorable episodes of “Voyager,” significantly within the present’s later years.
Mark Lenard
Mark Lenard has the uncommon distinction of not solely taking part in a number of Star Trek characters, but in addition attending to play a Romulan, Vulcan, and Klingon in his time with the franchise. Lenard’s affiliation with Star Trek started by taking part in a crafty Romulan commander within the “Authentic Collection” 1st season episode “Stability of Terror.” Lenard’s most iconic Star Trek position got here the next season, taking part in Spock’s father Sarek, a task he reprised on “The Animated Collection,” a number of motion pictures, and “The Subsequent Technology.” Along with his tv roles, Lenard additionally performed an ill-fated Klingon commander in 1979’s “Star Trek: The Movement Image,” finishing his trifecta of Star Trek aliens.
Exuding gravitas each time he is on-screen, Lenard brings a form of traditional thespian presence to Star Trek, particularly in its early years. As both a Romulan or a Vulcan, Lenard conveys a lot emotion regardless of the visibly staid demeanor that each races are recognized for. Sarek’s scenes with Spock are among the many finest Leonard Nimoy has ever performed as his most iconic position, with the 2 actors bringing out their finest in one another. Equally, Lenard’s ultimate appearances as Sarek on “TNG” are completely heartbreaking, displaying the tragic finish of a fantastic man.
David Warner
By the point David Warner appeared for his guest-starring position on “The Subsequent Technology,” he had already played two different characters in separate Star Trek motion pictures. After taking part in a human in 1989’s “Star Trek V: The Remaining Frontier” and a Klingon in 1991’s “Star Trek VI: The Undiscovered Nation,” Warner performed a Cardassian on “TNG.” Warner’s sadistic Gul Madred seems on the Season 6 two-parter “Chain of Command,” who captures and tortures Jean-Luc Picard (Patrick Stewart). Madred torments Picard, intent on breaking his spirit, practically succeeding in doing so till Picard’s well timed launch.
Of all of the on-screen adversaries Picard has confronted over time, few match him in dignity and gravitas as Warner’s Madred. For as noble and magnanimous as Picard is, Madred is wickedly crafty and devious, relishing in punishing Picard in exceedingly grueling methods. Stewart and Warner had first collaborated collectively in a ’60s British stage manufacturing of Hamlet, sustaining a mutual respect for one another. This considerably enhances their efficiency collectively on “TNG,” giving Picard and Madred’s brutal dynamic an engagingly refined air.
Alice Krige
When the Borg debuted on “The Subsequent Technology,” they appeared as a real collective, with no clear particular person chief for them to rally behind. 1996’s “Star Trek: First Contact” introduced the Borg Queen, the singular entity main the Borg as they mounted a time-bending assault on Earth. Performed by Alice Krige, the Borg Queen survives her defeat in “First Contact,” reappearing in a guest-starring capability on the two-part “Voyager” collection finale. After a quick return on “Star Trek: Decrease Decks,” Krige reprised her position in a larger capability on “Star Trek: Picard” as the ultimate season’s overarching villain. For “Picard,” Krige voiced the character whereas Jane Edwina Seymour served as her physique double.
The Borg was rapidly established as the last word “TNG” enemy, with the stakes raised immeasurably each time they surfaced. With Krige because the Borg Queen, the Borg gained a figurehead to rally round and a sneering face to Picard and Seven of 9’s deep-seated trauma. “Voyager” had defanged the specter of the Borg considerably, however Krige’s return because the Queen bolstered that sense of hazard, one thing that Krige improves upon on “Picard.” The one adversary that may persistently rattle the usually stoic Picard and Seven of 9 to their core, Krige’s Borg Queen is an enemy for the ages.
John de Lancie
The very first antagonist Picard and the crew of the Enterprise face in “The Subsequent Technology” is not the Borg, the Klingons, or the Romulans, however Q. Played by John de Lancie, Q seems on the two-part “TNG” collection premiere, declaring himself an all-powerful decide observing humanity. Deciding on Picard as humanity’s consultant, Q threatens to make use of his reality-shaping powers to erase the species’ existence if he deems them unworthy. Past the premiere, Q would reappear at the least as soon as every season of “TNG,” culminating in him returning to his decide position within the two-part collection finale.
Star Trek retains bringing again de Lancie as Q as a result of he is so successfully compelling to look at, with the character alternating between adversary and ally on a whim. This distinction goes past “TNG,” with de Lancie reprising his position as Q on “Deep Area 9,” “Voyager,” “Picard,” and “Decrease Decks.” Q’s motives and methodology fluctuate in every look, typically taking part in as a mischievous trickster and typically as a real menace. Q’s flexibility as a personality not solely speaks to de Lancie’s prodigious performing but in addition the inherent malleability of Star Trek personified.
Ricardo Montalbán
Initially showing as a one-off villain on the “Authentic Collection” Season 1 episode “Area Seed,” Ricardo Montalbán performed the formidable Khan Noonien Singh. A genetically enhanced despot from the late twentieth century, Khan and his followers had been exiled into deep house earlier than being found by the Enterprise centuries later. Kirk is barely capable of defeat the revived Khan, marooning him and his individuals on a distant planet. Montalbán went on to reprise his position as Khan in 1982’s “Star Trek II: The Wrath of Khan,” cementing his villainous dynamic with Kirk and revitalizing the broader franchise.
In case there may be any doubt relating to Montalbán’s esteemed guest-star standing, his one-episode look was sufficient to encourage a whole film that includes his return. No different actor all through Star Trek historical past can stake that declare of being elevated to a main film villain after a single guest-star position. Thematically, if Star Trek depicts enlightened humanity as a post-scarcity utopia, Khan represents the sinister potential that the long run can yield. That effectiveness is sealed by Montalbán’s efficiency, magnetic each time he is on-screen and, like his character, as bodily imposing as he’s eloquent and sleek.
