Pandorum is a 2009 science fiction horror film directed by Christian Alvart, produced by Robert Kulzer, Jeremy Bolt and Paul W. S. Anderson (the latter two through their Impact Pictures banner), and starring Dennis Quaid and Ben Foster.

The film's title is a fictional slang term for a form of psychosis caused by deep space and triggered by emotional stress, leading to severe paranoia, delirium, and nosebleeds.

Improper emergence from the hibernatory state leaves them both with partial amnesia and possibly suffering from pandorum, a space-related disorder that causes psychosis when under emotional duress.

The ship experiences power surges caused by an unstable nuclear reactor, and they are unable to enter the bridge.

He flees and continues on and encounters an environmental scientist, Nadia, and a farmer, Manh, who does not speak English; both are hostile.

Leland has been awake for years, living off the water oozing through parts of the ship, the algae it creates, and resorting to cannibalism.

Payton encounters Corporal Gallo, who claims the ship is lost in space and that he killed his team in self-defense.

Leland feeds Bower's group and shows them mural drawings depicting what has happened: after Earth vanished following an unknown catastrophe, Gallo went insane, killed his crew, and induced pandorum in other passengers.

Aided by accelerated evolution from an enzyme meant to help colonists adjust to life on Tanis, the descendants have turned into cannibalistic mutants.

As they search the ship for the reactor, Bower hopes to find his wife in an area for family in hypersleep but remembers that she died with everyone else on Earth when she refused to join him.

When Bower and Nadia confront him, Gallo opens the shutters on the bridge's windows, revealing that the ship is adrift in deep space with no stars visible.

Taking advantage of Bower's mental state, Gallo argues they must maintain the violent society rather than revive civilization.

Nadia observes bioluminescent ocean life through the windows, and the computer displays that 923 years have elapsed since the mission launched.

However, it attracted the attention of filmmaker Paul W. S. Anderson and Jeremy Bolt, and they gave it to Impact Pictures, who green-lit it.

[7][8] Summit Entertainment handled foreign sales and presented Pandorum to buyers at the 2009 Cannes Film Festival.

The website's critical consensus reads, "While it might prove somewhat satisfying for devout sci-fi fans, Pandorum's bloated, derivative plot ultimately leaves it drifting in space.

[12] Science fiction magazine SFX stated that "Pandorum is the finest interstellar horror in years" and awarded the film 4 stars out of 5.
