The cast of Pitch Perfect is led by Anna Kendrick in the role of Beca Mitchell, but did Kendrick really sing all of her songs? The 2010s saw a variety of comedies that were a success with critics and audiences, and among the most popular ones is Pitch Perfect. Directed by Jason Moore and released in 2012, Pitch Perfect is loosely based on the non-fiction book Pitch Perfect: The Quest for Collegiate a Cappella Glory, by Mickey Rapkin, and it follows an all-girl a cappella group known as the Barden Bellas, from Barden University, as they compete against another a cappella group from their school to win Nationals.
