One of the hits at the Sundance film festival was a little sci-fi flick starring Sam Rockwell called Moon. Unfortunately I didn't see it, and based on the trailer and few clips we have for you below, I'm sorry I missed it.

Check them out after the jump.

Head over to IGN.com for an HD version of the trailer.

And here are five clips from the film:

Based on this the film looks like a cross between the working man, creepy vibe of Alien and 2001: A Space Odyssey. Here's the official synopsis, courtesy of IMDB.com:

Sam Bell (Sam Rockwell) is nearing the end of his contract with Lunar. He's been a faithful employee for 3 long years. His home has been Selene, a moon base where he has spent his days alone, mining Helium 3. The precious gas holds the key to reversing the Earth's energy crisis.

Isolated, determined and steadfast, Sam has followed the rulebook obediently and his time on the moon has been enlightening, but uneventful. The solitude has given him time to reflect on the mistakes of his past and work on his raging temper. He does his job mechanically, and spends most of his available time dreaming of his imminent return to Earth, to his wife, young daughter and an early retirement.

But 2 weeks shy of his departure from Selene, Sam starts seeing things, hearing things and feeling strange. And when a routine extraction goes horribly wrong, he discovers that Lunar have their own plans for replacing him and the new recruit is eerily familiar.

Before he can return to Earth, Sam has to confront himself and the discovery that the life he has created, may not be his own. It's more than his contract that is set to expire.

Very interesting looking and I'll definitely be checking this one out this summer.

Moon opens on June 12th, 2009.
