I wish that I too could have an army of mice minions to do my bidding. No, seriously, I do, well, I'd rather cat minions, but we all know that that's a joke, with them being our masters and all...
This is the first I've seen of this movie, which appears to be about a guy who "doesn't fit in" (typical) and has the ability to control a large number of mice, which he uses to, well, do his bidding. Hit the trailer I linked to (large) or if you're net-deprived go and choose a different size.
This one doesn't make me want to go see it as much as say, the Daredevil or Matrix trailers, but hey, you never know...
