Moon (2009)

Sam Rockwell stars as "Sam" a space dweller on the Far Side of the Moon, working for a private mining company.  Deployed for 3 years, he's coming to the end of his tour and is getting antsy.  On a outing to one of the mining outposts, named Matthew, Mark, Luke and John, he suffers an accident and wakes up in the infirmary, being tended to by GERTY, the computer (voiced by Kevin Spacey).

He later discovers there is another person on the space ship, his twin, although he does not recognize him as such.  It turns out that the private forces of evil are cloning Sam.  GERTY is the  overseer of such activities.

Very reminiscent of 2001:  A Space Odyssey with the talking computer, the spare space ship, and the foreboding sense of what the future might actually look like.  A selection of the 2009 Sundance Film Festival, it certainly had the look of that.

However, it was a very thin version of 2001.   * * of 5.
