The first trailer for the musical comedy Pitch Perfect has gone online. The film stars Anna Kendrick and centers on an all-girls college a capella group that is in the process of rebuilding in order to defeat the rival all-boys group. Yes, the film is likely capitalizing on the country’s sudden obsession with Glee, The Voice, etc., but this trailer is saved by the electric charm of Kendrick and Bridesmaids standout Rebel Wilson’s impeccable sense of humor. In other hands Pitch Perfect has all the makings of a Step Up copycat, but with the promising chemistry between Kendrick and Wilson, Avenue Q’s Jason Moore in the director’s chair, and Elizabeth Banks producing, I’m definitely interested to see more. Also, as if Kendrick wasn't already one of the coolest people around, the girl's got an impressive voice to boot.

Hit the jump to watch the trailer. The film also stars Brittany Snow, Anna Camp, John Michael Higgins, Adam DeVine and Christopher Mintz-Plasse. Pitch Perfect opens on October 5th.

Here’s the official synopsis for Pitch Perfect:

Beca (Anna Kendrick) is that girl who’d rather listen to what’s coming out of her headphones than what’s coming out of you. Arriving at her new college, she finds herself not right for any clique but somehow is muscled into one that she never would have picked on her own: alongside mean girls, sweet girls and weird girls whose only thing in common is how good they sound when they sing together, in the new out-loud comedy Pitch Perfect.

When Beca takes this acoustic singing group out of their world of traditional arrangements and perfect harmonies into all-new mash-ups, they fight to climb their way to the top of the cutthroat world of college a cappella. This could wind up either the coolest thing they’ll ever do or the most insane, and it will probably be a little of both.

Loaded with new takes on old favorites to hits of right now that are seamlessly mixed together, mashed-up and arranged like you’ve never heard before, Pitch Perfect is directed by Jason Moore, who opened our eyes to the very misbehaved life of puppets in the surprise Broadway sensation Avenue Q.
