Moon is a fantastic sci-fi exploit for film-fanatics who enjoyed cult classics like 2001: A Space Odyssey, where it focuses on the emotions of the characters, or just the one person as it seems in this masterpiece on Duncan Jones' debut. A film about loneliness, Sam Rockwell is fantastic as the lonely astronaut finishing his long contract on the Moon's surface for a company which harvests helium. Keeping him sane, is a well thought out mechanical companion named GERTY, softly voiced by Kevin Spacey, in which you can draw comparisons with the malfunctioning HAL 9000 in Kubrick's classic. However, is Sam alone on the Moon? Or is his hallucinations just his incredible loneliness taking it's toll on him, or is GERTY and the company covering up a terrible secret on the Lunar Surface? This film keeps you guessing until the very end, and it makes sense more every time you watch it. A perfect insight into how good old-fashioned low-budget talkies can be, 100% worth a look.
