Moon is a smart and fascinating new sci-fi film starring Sam Rockwell as a man living and working by himself on the moon for three years.
Is he sane or is he hallucinating? That's the question you'll ask when Rockwell keeps running into himself and engaging in conversation.
This is a heady, psychological study of isolation and rather than making a film about special effects, the director has created a challenging mind-bender.
Moon is written and directed by Duncan Jones, and that should tell you something - he's the British son of pop star David Bowie.
