The first trailer for Clint Eastwood’s new movie Gran Torino is here. In it he plays a bitter, pissed off old man with a very big gun, who’s had it up to here with punk teenagers and decides to deliver some punishment. Actually, having watched the trailer I’m fairly convinced that Eastwood is actually playing Principal Strickland from Back to the Future. You expect him at any minute to start screaming “slackers!” as he runs into the street firing off rounds.

The trailer’s great though and Principal Strickland deserves his own film. Get your first look at Clint’s return to being a pissed off badass, in the Gran Torino trailer below:
