Worst Sci-fi Movies of All Time

Some sci-fi films swing big and miss even bigger, leaving behind production troubles, unhappy audiences, and legendary cautionary tales. This list looks at titles that struggled with execution, reception, or both, drawing on things like chaotic shoots, disastrous box office runs, and infamous creative choices that are still discussed today.

‘Battlefield Earth’ (2000)

This adaptation of L. Ron Hubbard’s novel is set in the year 3000 and stars John Travolta and Barry Pepper. Director Roger Christian filled the film with tilted shots and heavy prosthetics to depict an alien occupation of Earth. The movie won a stack of Razzie Awards after critics panned its writing and design choices. Its theatrical run fell far short of expectations and ended any hopes for a planned sequel.

‘Plan 9 from Outer Space’ (1959)

Ed Wood pieced this film together using footage of Bela Lugosi shot before the actor’s death. The production relied on minimal sets, visible wires, and stand-ins to complete missing scenes. Distribution was limited and reviews were harsh even at the time. Decades later it gained a cult reputation as a template for low budget sci-fi gone wrong.

‘Highlander II: The Quickening’ (1991)

A disputed production in Argentina led to a version that replaced the original’s fantasy lore with an alien origin. Multiple cuts of the film circulated after release as producers and creatives fought over edits. Fans rejected the mythology shift and continuity changes. The franchise needed later entries to walk back many of this sequel’s choices.

‘The Adventures of Pluto Nash’ (2002)

Eddie Murphy led this lunar-set comedy about a nightclub owner caught in a crime plot on the Moon. The film endured delays and reshoots before finally reaching theaters. Marketing failed to connect and the box office was extremely weak. Its large reported budget turned the project into a famous financial flop.

‘Supernova’ (2000)

This space rescue thriller went through directors and edits, with Walter Hill credited under a pseudonym. Postproduction brought in outside help for reworking scenes and tone. The theatrical cut felt stitched together from competing ideas. Audiences stayed away and critics cited the rocky development as visible on screen.

‘Ultraviolet’ (2006)

Milla Jovovich starred in a futuristic story about a bioengineered heroine fleeing a militarized government.

Director Chris Roberts adapted his hit video game series into a feature with space dogfights and naval-style pilots.

The adaptation missed the tone fans expected and stalled the brand in theaters.

‘The Darkest Hour’ (2011)

Set in Moscow, this alien invasion film featured invisible energy beings that disintegrate targets. A 3D release aimed to boost spectacle but could not overcome weak reception.

‘Moonfall’ (2022)

This disaster epic pitched the Moon as a technological megastructure that goes off course. Production leaned on massive CGI sequences and elaborate destruction. The release faced pandemic era headwinds and could not recoup its costs in theaters. Critical reaction centered on the story’s leaps in logic and thin character work.

‘After Earth’ (2013)

Will Smith and Jaden Smith headlined a survival tale on a future Earth reclaimed by nature. The film’s campaign emphasized a new sci-fi mythology but early reviews were negative. Domestic box office underperformed while international markets provided only partial relief. The poor reception paused plans for a wider transmedia expansion.
