Pandorum

A seminal work in the 'haunted house in space' genre, Alien offers a blend of science fiction and horror akin to Pandorum. The tension of a lethal extraterrestrial threat aboard the Nostromo spacecraft makes this movie a timeless choice for aficionados of chilling space tales.

Event Horizon shares the theme of a forsaken spaceship harboring a dreadful secret. Fans of Pandorum's claustrophobic and dark atmosphere will find similar chills in this sci-fi horror as a crew investigates a missing spacecraft that re-emerges with a malevolent force.

In Sunshine, the crew of a space mission to reignite the dying sun faces psychological and physical threats in isolation, akin to the tense, eerie narrative of Pandorum. Both films share an edge-of-your-seat quality that keeps viewers deeply invested in the characters' fates.

With a focus on survival in an alien world, Pitch Black follows a group of marooned space travelers contending with predatory creatures. It shares with Pandorum the underlying threat of monstrous beings and the tension of humans in an alien environment.

Cube might not be set in space, but its themes of survival in a treacherous, confined environment and the psychological descent of the characters will resonate with fans of Pandorum who enjoy a blend of psychological thriller and horror elements.
