Moon

As he nears the end of a lonely three-year stint on the moon base Sarang, astronaut Sam Bell (Sam Rockwell) begins to hear and see strange things. It's not long before Sam suspects that his employer -- the conglomerate LUNAR -- has other plans for him. Featuring Kevin Spacey as the voice of a robot, this sci-fi thriller also stars Matt Berry and Kaya Scodelario. The film was an official selection at the Sundance Film Festival.
