First Glee, then Joyful Noise...American can't get enough of singing teens! The new musical movie Pitch Perfect is the latest to tackle the trend, as the film takes a look into the world of collegiate competitive a cappella groups. Tony nominee Anna Kendrick (High Society) stars as the newbie to an all girl singing group, who inspires the ladies to take a fresh approach to their performances. The movie also features stage veterans Skylar Astin (Spring Awakening), Anna Camp (All New People) and Hairspray film star Brittany Snow. Take a look at the trailer, which includes renditions of '90s hits "The Sign" and "No Diggity," then catch the movie when it hits theaters October 2.
