UPDATE and solution (14 March 2012):
Again Alexander Rabitsch ↵did it way faster than I am able to update: ‘He’s a miner … not a ’49-er, but a sci-fi miner, played by Sam Rockwell … the movie’s called Moon …’ That is so, and the answer is not only correct but a wise one, too: What I had in mind as an answer would’ve been a complete spoiler! So, go and watch ‘↑Moon,’ directed by ↑Duncan Jones (2009). And if you’re already at it, watch Mr Jones’ [who is David Bowie’s offspring, btw] excellent ‘↑Source Code‘ (2011) as well.
