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.

A Cinderella Story: Once Upon a Song, available on DVD and digital download, is a modern twist on the timeless classic. Terrified of being put in foster care, Katie (Lucy Hale) does whatever her stepmother (Missi Pyle) and step-siblings demand. But, when the Massive Records company president (Dikran Tulaine) decides to scout for new talent at the showcase at a prestigious private school, where his son Luke (Freddie Stroma) is the newest student, Katie hopes she can land a recording contract and get the guy. Forced to lay down tracks and perform for her untalented stepsister (Megan Park) Bev, in order to help her pursue her own quest for stardom, Katie has to find the courage to tell her true love that it’s been her all along.

At the film’s press day, actor Freddie Stroma (best known for his role as Cormac McLaggen in the Harry Potter films) spoke to Collider for this exclusive interview about how this Cinderella story is different from the classic fairy tale, all of the fun extras and behind-the-scenes interviews that will be included on the DVD, why he ended up beat-boxing in the movie, and how much fun they all had bonding as a cast. He also talked about his latest film, The Philosophers, which co-stars fellow Harry Potter actor Bonnie Wright. Check out what he had to say after the jump:
