Science fiction is a genre built on grand ambitions—alien worlds, futuristic tech, and mind-bending concepts. But with such lofty goals comes a greater chance of spectacular failure. While a bad romance or thriller can only go wrong in a few ways, a sci-fi film can stumble in its story, effects, world-building, dialogue, and casting all at once. The following movies managed to hit nearly every pitfall, earning their spots as some of the worst in film history.
10. Battlefield Earth (2000)
Set in the year 3000, humanity has been enslaved by the alien Psychlos for a millennium. John Travolta plays Terl, the security chief who plots to use a human captive to mine gold. That human, Jonnie Goodboy Tyler (Barry Pepper), eventually sparks a rebellion. Based on L. Ron Hubbard's novel, Travolta spent nearly a decade pushing to bring it to the screen—which makes the final product even more painful.
The director's constant tilted camera angles make you feel like you're watching on a rocking boat. The Psychlos sport dreadlocks and platform boots, and Forest Whitaker delivers his lines with a straight face that only adds to the absurdity. It swept seven Razzies and was later named Worst Picture of the Decade.
9. The Last Airbender (2010)
M. Night Shyamalan adapted the beloved Nickelodeon animated series into a live-action film, cramming a 20-episode season into 103 minutes. Aang (Noah Ringer) awakens after a century frozen in ice to stop the Fire Nation, joined by Katara (Nicola Peltz) and Sokka (Jackson Rathbone), while Prince Zuko (Dev Patel) pursues them.
The casting drew backlash before release, with white actors playing the heroes and non-white actors as villains. Character names were mispronounced, and the 3D conversion made an already dark film even murkier. Fans never forgave it, and it won five Razzies.
8. After Earth (2013)
Will Smith stars as General Cypher Raige, who crash-lands on a hostile Earth with his son Kitai (Jaden Smith). With both legs broken, Cypher directs Kitai via radio to find a rescue beacon. The story, developed by Will Smith himself, was directed by Shyamalan.
The father remains seated for most of the film, while his son battles creatures that hunt by sensing fear. The repeated mantra "fear is a choice" loses its impact quickly. Jaden earned a Razzie nomination, and the film underperformed critically and commercially.
7. The Happening (2008)
People across the Northeast begin committing suicide en masse, and science teacher Elliot Moore (Mark Wahlberg) flees with his wife Alma (Zooey Deschanel). The culprit? Plants. Yes, plants. Wahlberg's iconic scene involves calmly talking to a plastic plant to avoid detection.
Even the actors seem baffled by the dialogue, and Wahlberg has since joked about it. The R-rating at least allowed the grim suicides to be depicted with appropriate severity.
6. Jupiter Ascending (2015)
The Wachowskis, who gave us The Matrix, delivered this convoluted space opera. Jupiter Jones (Mila Kunis), a toilet cleaner, discovers she's the genetic reincarnation of an alien queen and owns Earth. Channing Tatum plays a half-wolf soldier with anti-gravity boots, and Eddie Redmayne chews the scenery as the villainous Balem Abrasax.
The plot is so tangled that characters spend entire scenes explaining planetary ownership. Redmayne's whisper-growl delivery became legendary, earning him a Razzie the same year he won an Oscar. And yes, bees recognize Jupiter as royalty—played completely straight.
5. Transcendence (2014)
Johnny Depp plays Will Caster, a scientist whose mind is uploaded to a computer after an assassination attempt. His wife Evelyn (Rebecca Hall) keeps the system running, and the digital Will grows increasingly powerful. This was the directorial debut of Wally Pfister, Christopher Nolan's cinematographer.
With Depp confined to a screen for most of the runtime, the film never builds tension. The script was once a hot Hollywood property, but the execution fell flat. It's a cautionary tale about ambition without a clear vision.
