The trailer for the sci-fi film Moon is out, starring Choke actor Sam Rockwell and the voice of Kevin Spacey. As you can probably guess, it takes place on the moon. Things go awry right before homeboy is set to go home upon completing his 3-year mission. But let's be honest, it could be a 4 hour movie abut waiting in the dentist's office and if both San Rockwell and Kevin Spacey were in it, I'd be there. They both kind of rule.
