Duncan "David Bowie's son" Jones's low-fi sci-fi, which features no sex, very little violence or budget and ostensibly one actor (Sam Rockwell), is a cerebral delight. Sam Bell (Rockwell), like ET, just wants to go home; three years working on the dark side of the Moon with only Kevin Spacey's creepy voice, as spaceship computer, Gerty, will do that. Sam's suffering hallucinations and headaches and a near-fatal accident lands him in the infirmary. He awakes to find a younger version of himself stalking his bed. Jones's intelligently constructed, distinctly retro film borrows from the best – Silent Running, Alien, Blade Runner, Solaris, Dark Star and Outland – and is the best kind of paranoia movie, with unfussy dialogue, a heightened sense of isolation and corporate wickedness to the fore.
