Gerard Butler, the guy who played King Leonidas in 300, stars in Gamer, a new movie that is due out September 4 in the US and now gets its first trailer. The movie is set in a future world, in which humans can remotely control other humans in mass-scale MMOGs, making them kick each other’s butts.

The game in the movie is called Slayers and the star player is a death row inmate called Kable (Butler) who is forced to battle other players in a prison to regain his freedom.

I don’t think Gamer will win any Oscars, but the plot sounds kind of interesting (like a mix between Running Man and Death Race). And the trailer is full of brainless action.
