I'd wanted to see this when it was at the Cleveland Film Festival back in the spring. Sadly, we were help my mother recover after her surgery and couldn't attend. Fortunately, it got a limited release at the cinematheques and such, so we were able to see it last night.
This film is along the lines of 2001: A Space Odyssey more than your standard space film fare. It's a little more stark and won't really please the masses, but it is a really good film.
The premise of the film is a good one. (taken from IMDB) Sam Bell has a three year contract to work for Lunar Industries. For the contract's entire duration, he is the sole employee based at their lunar station. His primary job responsibility is to harvest and periodically rocket back to Earth supplies of helium-3, the current clean and abundant fuel used on Earth. There is no direct communication link available between the lunar station and Earth, so his only direct real-time interaction is with GERTY (voiced by Kevin Spacey), the intelligent computer whose function is to attend to his day to day needs. With such little human contact and all of it indirect, he feels that three years is far too long to be so isolated; he knows he is beginning to hallucinate as the end of his three years approaches. All he wants is to return to Earth to be with his wife Tess and their infant daughter Eve, who was born just prior to his leaving for this job. With two weeks to go, he gets into an accident at one of the mechanical harvesters and is rendered unconscious. Injured, he awakens back at the station in the infirmary, he assumes assisted by GERTY. GERTY tells him that a rescue team named Eliza will come to the station to clean up the aftermath of the accident. After his recuperation, he takes an unauthorized trip back to the broken harvester, where he makes an unexpected discovery. Because of his find, he begins to doubt his sanity, then his true identity, then the company and GERTY's willingness to do what is best for him. Because of his resulting beliefs, his sole mission becomes how to get back to Earth on his own.
I highly recommend this film if you like quiet, intellectual sci-fi. It's a good story and really wonderfully directed and acted. Sam Rockwell should get some sort of nomination for playing against himself.
