Sam Bell (Sam Rockwell) is stationed, alone, on the Moon. Nearing the end of his multi-year contract to man a largely automated mining facility, he works as a glorified handyman, wanders the base's empty hallways, watches videos of his wife and daughter back on Earth, and talks with the base's kinda-sweet, kinda-creepy computer (voiced by Kevin Spacey). Rockwell's Sam is a likeable, blue-collar guy with a lonely, shitty job, and director Duncan Jones gracefully captures the guy's weary isolation. You feel for Sam—which makes it all the more messed up when things start to get weird. by Erik Henriksen
