Moon is a 2009 British science fiction drama directed by Duncan Jones in his feature debut, starring Sam Rockwell in a tour-de-force solo performance. Rockwell plays Sam Bell, the sole human worker at a lunar mining station operated by the corporation Lunar Industries, who is nearing the end of his three-year contract when he begins experiencing hallucinations and discovers a disturbing truth about the nature of his mission and his own identity. Duncan Jones crafted one of the most intelligent and emotionally resonant science fiction films of its decade on a modest $5 million budget, using miniature models rather than CGI for the lunar surface and relying entirely on Sam Rockwell's extraordinary ability to carry a film almost single-handedly.

Kevin Spacey's voice as GERTY, the station's AI companion whose simple smiley-face display conveyed complex emotional undertones, was a clever homage to and subversion of 2001's HAL 9000. Clint Mansell's piano-based score was hauntingly beautiful. Moon earned $10 million worldwide and launched Duncan Jones's directing career.
