The Bellas are back and harmonizing with some pitch pipes, baby. Following the success of the original Pitch Perfect films, a trilogy will be complete with the arrival of Pitch Perfect 3 in December, which will follow the a cappella group out of Barden as they “go on a USO tour” around the world. Not too much is revealed plot-wise in this teaser-trailer besides some cute behind-the-scenes shenanigans with the cast. The returnees include Rebel Wilson, Anna Kendrick, Anna Camp, Brittany Snow, and Hailee Steinfeld; while the newbies are John Lithgow, DJ Khaled, and Ruby Rose — but they all seem to be having a grand ol’ time, regardless. If you don’t see it in theaters, Fat Amy will body-slam you.
