Astronauts Payton (Dennis Quaid) and Bower (Ben Foster), serving on a space ark which is conveying the last Earth folks to a fresh new planet, come out of cryo-sleep suffering from partial amnesia.
The ship is malfunctioning, and degenerate body-pierced mutant cannibals are running wild, so Bower takes a perilous journey through dark tunnels to fire up the reactors while Payton argues with a pessimist mystery man (Cam Gigandet) in the control room.
Pandorum is a hodge-podge of familiar sci-fi stuff, which feels as if it were adapted from a computer game – it’s a Paul W.S. Anderson production, directed by Christian Alvart (Case 39) – and spends so much time in the dark, with irritating jittery edits and indistinct action, that it barely flickers into life when all its mysteries are resolved.
