Moon is the story of astronaut Sam Bell (Sam Rockwell) who is close to the end of a 3 year stint digging into the Moon in order to transfer energy to Earth. Sam's main contact on the Moon is GERTY, a computer voiced by Kevin Spacey.
Personally I think Moon is a major milestone in terms of taking a chance on a first time director. Duncan Jones has created not only a solid sci-fi film for his first effort but also a film that is now recognised as "one the Oscars snubbed"
Duncan Jones made Moon for $5 million, Which for a Sci-Fi film especially is a miniscule budget. He worked extremely well with what he was given and had a leading actor that was willing to give the film everything he had.
Sam Rockwell's performance is fantastic, He spends all of the film practically acting with himseld and shows major potiental for upcoming films. I can't really go into much detail about the film as less than an hour in something happens that flips it straight onto its head. The twist like move does make the rest of the film kind of trippy but you can follow it.
I urge you to watch Moon. Even if you don't consider yourself a Sci-Fi fan simply watch Sam Rockwell's performance. I know I'm not the only one to say this but it's a travesty that Moon and Sam Rockwell aren't up for Oscars this year.
