Sci-fi moviesoften contain their fair share of action, so it’s no surprise that plenty of action movie heroes have appeared in some fantastically strange science-fiction films. The nature of sci-fi stories means they embrace unbelievable concepts and tap into innate human fears around technology and progress. While this can lead to some undeniable movie classics, it also means that major box office stars sometimes end up participating in movies that were just downright strange and destined to become beloved cult classics or, in other instances, reviledbox office bombs.
Many of thebest sci-fi movies of all timehave leaned into the bizarre and unusual sides of the genre, as technological tales of transcendent terror have captivated audiences and pushed narrative boundaries. While some strange sci-fi movies withacclaimed action starshave struck a chord with viewers, others were doomed to fester in obscurity. While they may not all represent the very best cinema has to offer,all these sci-fi films were unique and interesting in their own way.

10Silent Rage (1982)
Chuck Norris as Sheriff Dan Stevens
The martial arts movie icon Chuck Norris has become so associated with strength and fortitude that there was a period whenChuck Norris memeshad practically taken over the internet. As a black belt in Tang Soo Do, Brazilian jiu-jitsu, and judo, Norris’ history in the United States Air Force and experience fighting opposite his friend and co-star Bruce Lee made him one of the quintessential action stars of the 20th century. While Norris usually showed off his skills in pure martial arts action movies likeA Force of One, in 1982, he gifted the world with a strange sci-fi horror calledSilent Rage.
Silent Ragestarred Norris as a sheriff attempting to stop an indestructible manwho has gained super resilience due to a medical experiment. As a chance to show off Norris’ incredible martial arts talents while also delivering an unusually genre-melding story,Silent Ragewas an enjoyable tongue-in-cheek satire on movie tropes that featured plenty of fun moments. As one of the most unique entries in Norris’ action movie filmography,Silent Rage’smix of kung fu, horror, and sci-fi made it stand out as an underappreciated 1980s classic.

9Johnny Mnemonic (1995)
Keanu Reeves as Johnny
FutureJohn Wickstar Keanu Reeves has been consistently associated with science fiction, as he famously portrayed Neo inThe Matrixfranchise. However, not everyone will be aware that prior to gaining his role in that series by the Wachowskis, Reeves also starred in another, much less acclaimed cyberpunk movie. This wasJohnny Mnemonic, a fascinating action sci-fibased on a story by William Gibsonset in a high-tech, dystopian futuristic society.
With Reeves as Johnny, a data courier with an overloaded brain implant,Johnny Mnemonicwas a fascinating technological exploration that was badly received upon release. However, it has since earned a reputation as a true cult classic and was even re-released in 2022 asJohnny Mnemonic: In Black and White, a version that Gibson stated (viaScreen Slate) better represented his original vision. AlthoughJohnny Mnemonicmay not be as well known as Reeves’ other sci-fi roles, this was a fascinating cyberpunk precursor toThe Matrixwith plenty to say about the nature of technology and society’s relationship with it.

8Battlefield Earth (2000)
John Travolta as Terl
The astounding career of John Travolta saw the actor become a major star during the 1970s, with roles inGreaseandSaturday Night Feverbefore he reinvented himself during the 1990s as an action star with acclaimed parts inPulp FictionandFace/Off. This interest trajectory opened the doors forTravolta’s passion project of adapting L. Ron Hubbard’s 1982 movieBattlefield Earth. As a notable Scientologist, Travolta has long been associated with the controversial figure of Hubbard, who shifted from a sci-fi writer to a leader of his own religion in the latter half of the 20th century.
Battlefield Earthfollowed a rebellion against the alien Psychlos, who have ruled Earth for 1,000 years and starred Travolta as Terl, an Earth-born security chief. While Travolta may have had a personal interest inBattlefield Earthbeing made, this did not result in an acclaimed movie as itwas slated by critics and boasts an abysmal 3% score on Rotten Tomatoes. While viewers may find enjoyment in campy, ugly, and poorly acted sci-fi in a so-bad-its-good kind of way,Battlefield Earthwas a box office bomb of very little merit.

Battlefield Earth
In the year 3000, Earth is dominated by the Psychlos, a powerful alien race led by Terl, who use humans as slaves to strip the planet of resources. Reduced to a primitive state, humanity’s survival rests on Tyler, a captive who takes on the mission to save his people from alien tyranny.
7The 6th Day (2000)
Arnold Schwarzenegger as Adam Gibson
Action movie icon Arnold Schwarzenegger gained his big break in the sci-fi classicThe Terminatorand since then has occasionally returned to the genre. While this led to some career highs such asTerminator 2: Judgment DayandTotal Recall, one strange attempt to recapture that magic was The 6th Day. Set in the then far-flung future of the year 2015, Schwarzenegger starred as both Adam Gibson and his clone in this story of a conspiracy to kill a billionaire gone wrong that failed to live up to the heights of its star’s very best sci-fi movies.
WhileThe 6th Dayhas an intriguing premise and features some great action sequences, the critical reception was poor.The 6th Dayended up earning three Razzie Award nominations for Schwarzenegger, one for Worst Actor as Adam, one for Worst Supporting Actor as Adam’s clone, and one for Worst Onscreen Couple for Adam and his clone, but lost all three toBattlefield Earth. AlthoughThe 6th Daymay not have been Schwarzenegger’s crowning achievement, it was still an enjoyable depiction of cloning made in an era when the endless possibilities of this developing science intrigued the general population.

The 6th Day
In The 6th Day, Adam Gibson discovers he’s been illegally cloned. As he uncovers a conspiracy in a world where cloning is advanced but controversial, the film explores the ethical dilemmas and dangers of human cloning.
6Timecop (1994)
Jean-Claude Van Damme as Agent Max Walker
Martial arts star Jean-Claude Van Damme has consistently shown off his karate and kickboxing skills in movies likeBloodsportandKickboxer. These iconic roles saw Van Damme playing villains and heroes in many more action movies and sci-fi films likeUniversal SoldierandCyborg. However,Van Damme’s most successful cinematic success was inTimecop, a box office hit that earned over $100 million (viaThe Numbers) at the global box office.
InTimecop, Van Damme played Agent Max Walker, a cop from 1994 in a world where time travel has been made possible, and criminals exploited it for money and power.Timecopsaw Van Damme traveling through time, solving crimes, and undercovering a vast political conspiracy.

5Ghosts of Mars (2001)
Jason Statham as Sergeant Jericho Butler
Before becoming known as one of Britain’s greatest action stars, Jason Statham had a role in John Carpenter’s divisive sci-fi space horrorGhosts of Mars. This was the first glimpse of Statham’s bright future in action movies as he portrayed the smarmy anti-hero Sergeant Jericho Butler, who accompanied Ice Cube in a complex story of possessed ghosts and convicted criminals on a colonized 22nd century Mars. WhileGhosts of Marsflopped at the box office and was badly received, its action movie stylings helped lay the foundations for Statham’s career moving forward.
AlthoughGhosts of Marsmay have its apologists, the truth was that the film didn’t really work. Despite being the man behind several sci-fi classics likeThe ThingandEscape from New York,Ghosts of Marsmissed the mark and was a convoluted film full of campy and corny dialogue. However, despite these shortcomings, it’s still enjoyable to see Statham in such an early role as he’s carving out a career that would later go from strength to strength.

4Predestination (2014)
Ethan Hawke as Agent Doe
While Ethan Hawke got his start in movies such as the coming-of-age classicDead Poet’s Societyand Richard Linklater’s romantic masterpieceBefore Sunrise, he’s also embraced action movie roles throughout his career. From his Oscar-nominated performance inTraining Dayto the genetic themes of the dystopian sci-fiGattaca, Hawke has truly done it all. Out of his many roles, perhaps the most unusual was as Agent Doe in the time travel thrillerPredestination.
Predestinationstarred Hawke opposite futureSuccessionstar Sarah Snookin a complex and thematically rich tale of confused identity. As the lines between Hawke and Snook’s character’s history started to blur,Predestinationslowly built toward an unpredictable twist that puts the entire movie into a new perspective. As a clever and ambitious sci-fi movie, Predestination was one of Hawke’s most underrated roles.

3Zardoz (1974)
Sean Connery as Zed
Sean Connery completely subverted the audience’s expectations of him as the secret agent of James Bond with his outrageous role as Zed inZardoz. This unusual sci-fi fantasy from director John Boorman was one of the most underrated movies of the 1970s, as its trippy visuals and special effects told the post-apocalyptic story of stone-worshiping barbarians growing food for a hidden elite called the Eternals. With Zed caught between two camps that build toward a brutal battle and shootout,Zardozwas truly one of the most idiosyncratic movies of its era.
Zardozwas shot in Wicklow, Ireland, and featured Connery in a notoriously skimpy outfit as viewers caught a glimpse of more than they bargained for from the former 007. WhileZardozwas badly received when it was first released, it’s since grown to become a beloved cult classic. While it may be true thatZardozwas over-ambitious, totally outrageous, and often pretentious, it was still wildly entertaining and a supreme piece of 1970s weirdness.

While he’s best known for the sports movie success ofRockyand his action-hero persona in theRambofranchise, Stallone has also tackled animation, comedy, and drama movies. One unusual sci-fi offer from Stallone was the excellent 1990s action filmDemolition Man, a tale of a cryogenically frozen cop and criminal who once again encounter each other in a peaceful future.
Demolition Manfeatured Stallone as determined risk taking police officer John Spartan, while Wesley Snipes played his arch nemesis Simon Phoenix, a deranged crime lord with a passion for chaos. As the two re-emerged in a utopian future, it was thrilling to watch howDemolition Manblended fast-paced thrills with enjoyable societal satire. As one of Stallone’s most underrated movies,Demolition Manwas a strange film that remains endlessly enjoyable more than three decades after its release.
