For those who've been waiting to see Rainn Wilson absolutely rock out in The Rocker, a brand new trailer for the film has just premiered over at Yahoo. Originally, this flick was supposed to hit screens about a month or so ago, but it's since been pushed to August 1 -- and, from the looks of this trailer, I can totally see this being that late-summer comedy hit that builds buzz and ends up doing quite well at the box office. Or maybe I'm just a sucker for 80's drummers who get a chance to win back a piece of stardom by playing their nephew's high school prom.

The Rocker follows Robert "Fish" Fishman (Wilson), a once successful drummer with a prominent '80s hair band who was tossed to the side right when their popularity began to grow. Now, years later, when Fish's nephew needs an extra drummer for his prom band, that dude from The Office steps up to the plate and takes these kids on one helluva wild ride. Check out the trailer and let us know what you think. Can Rainn Wilson hold down the fort on this one all on his own?
