Moon is the directorial debut for Duncan Jones, a British film maker.  It is an independent film about Sam Bell (Sam Rockwell) who works for Lunar Industries running a mining station on the moon.  He is the only human there with GERTY the robot (Kevin Spacey) as his only companion.  He is contracted for a 3 year shift, with the movie primarily focusing on the last 2 weeks.  Communication is limited due to satellite problems and the companies lack if interest in fixing it.
