An accomplished character actor with an instantly recognizable voice, Sean Harris is best known to mainstream audiences for his role as Solomon Lane in the Mission: Impossible movies. Renowned for his work in prominent historical dramas like The King, Macbeth, and The Green Knight, the Englishman also features in Ridley Scott's Alien franchise, playing a minor role in prequel outing Prometheus.

Harris plays Fifield in the 2012 sci-fi horror movie, a temperamental geologist brought along on the mission to obtain rock samples from the Engineers' purported home world. Boasting a red mohawk haircut to complement an array of futuristic facial tattoos, Harris is virtually unrecognizable in his role as Fifield. It's a state of affairs that decidedly doesn't improve after his character is duly infected, turned into a feral monstrosity, and incinerated with a flamethrower.

A reboot of the Planet of the Apes movie series, 2011's Rise of the Planet of the Apes sought to modernize the franchise by depicting the origins of Andy Serkis' Caesar, a genetically enhanced chimpanzee who eventually goes on to lead an ape uprising against humanity. Featuring James Franco in the leading role, the film also boasts an unlikely cameo appearance from one of the stars of the wildly popular Harry Potter franchise.

Tom Felton, the man charged with bringing the live action depiction of Draco Malfoy to life, appears in the movie as Dodge Landon. Much like his wizarding counterpart, Felton's dramatic charge isn't any more pleasant this time around; the Englishman's character is a sadistic caretaker who amuses himself by cruelly abusing the animals he is responsible for. Landon meets his end at Caesar's hands after he is electrocuted trying to prevent the chimp's escape.

Introducing the Somali-American performer to a global audience, Barkhad Abdi's Academy Award nominated bow as the pirate Abduwali Muse in 2013's biographical action drama Captain Phillips served as the actor's breakout role. Propelled into the mainstream by his superb performance, Abdi went from a completely unknown commodity to an instantly recognizable Hollywood face virtually overnight.

The actor's celebrated work in Captain Phillips led to a number of roles in standout Hollywood offerings, including a brief appearance in the acclaimed Blade Runner sequel, 2017's sci-fi masterpiece Blade Runner 2049. Abdi can be seen fleetingly in an electric cameo as Doc Badger, a black-market pawn shop operator who can allegedly obtain anything for the right price. Ryan Gosling's K encounters Badger while attempting to analyze the origins of a mysterious wooden horse.

Instantly marking herself out as a name to watch with a mesmerizing turn in Robert Eggers' 2015 folk horror outing The Witch, Anya Taylor-Joy has swiftly become one of Hollywood's most prominent and sought after young performers. Still only just twenty-eight, the actress is best known for her acclaimed bow as chess prodigy Beth Harmon in Netflix's 2020 miniseries The Queen's Gambit, in addition to her lauded performances in the likes of Emma, The Menu, and Furiosa: A Mad Max Saga.

Apparently unsatisfied with her lengthy and enviable list of credits, the British-American Emmy nominee also boasts an uncredited cameo appearance in 2024's smash hit Dune: Part Two. Taylor-Joy appears as Alia Atreides, the unborn sister to Timothée Chalamet's lead protagonist Paul, and a significant character who goes on to play a prominent role in Dune's future canon.

Best known for his Oscar-nominated bow in 1986's Platoon, actor Tom Berenger is renowned for breathing life into one of the best war movie villains of all time in the terrifying Sergeant Robert "Bob" Barnes. While Berenger is also known for his work in the likes of Training Day and the Sniper franchise, the American's acclaimed work in Oliver Stone's seminal war offering remains his most celebrated and widely recognized role to this day.

While Platoon may be the film that Berenger finds his name inextricably linked with, the actor also features in a minor role in one of the finest sci-fi movies of all time. Berenger plays Peter Browning in Christopher Nolan's Inception, a father figure to Cillian Murphy's Robert Fischer who is used as a patsy by Leonardo DiCaprio's Dom Cobb in an effort to gain the billionaire's trust.

While James Franco has somewhat faded from the public eye following a string of disturbing controversies and allegations, the 127 Hours star remains one of Hollywood's most famous and instantly recognizable faces. The Academy Award-nominated actor usually receives top billing in the majority of his roles, meaning that a blink-and-you'll-miss-it appearance in one of cinema's most storied sci-fi franchises often goes overlooked.

Franco features briefly in 2017's Alien: Covenant, the follow-up outing to 2012's Prometheus and the second film in Ridley Scott's Alien movie prequel series. Franco plays Jacob "Jake" Branson, the Covenant's original captain and partner to Katherine Waterson's lead protagonist, Daniels. Branson tragically perishes in a fiery blaze during the film's opening sequences after his pod malfunctions during a solar burst. Franco can also be seen as Branson in a short promotional prologue released in the lead-up to the film's debut.

In addition to arguably being the most underrated film in the Predator franchise, Predators also happens to boast a cameo from a multiple Academy Award-winning actor during the story's early stages. Moonlight and Green Book star Mahershela Ali plays the minor role of Mombasa, a Revolutionary United Front death squad soldier from Sierra Leone who features briefly before being brutally killed during the group's first confrontation with the Predators in the movie's early goings.

Renowned for her film collaborations with her former husband, Tim Burton, Academy Award-nominated actress Helena Bonham Carter is one of cinema's most instantly recognizable faces. As well as her frequent appearances in Burton movies, the English film star has featured in some of the most acclaimed and celebrated films in recent memory, with prominent roles in the likes of Fight Club, The King's Speech, and the Harry Potter franchise.

Bonham Carter's lengthy list of credits even includes the storied Terminator franchise, with the actress playing a minor role in 2009's Terminator Salvation. The Les Misérables star plays Serena Kogan, a terminally ill doctor who persuades Sam Worthington's Marcus Wright to sign over his body for medical research following his execution during the movie's opening scenes. Bonham Carter's charge also appears during the film's climactic sequences, with the Skynet computer using Kogan's likeness to communicate with Wright.
