Pitch Perfect follows the Barden Bellas' journey to winning the ICCA Finals, a real competition that inspired the film. Anna Kendrick got her big break in the 2008 film adaptation of Stephanie Meyer's Twilight but reached a new level of notoriety for her role as Beca in Pitch Perfect. The film premiered in 2012, launching the world into an obsession with Beca's Cup song, which was actually a cover of the 1931 song "When I'm Gone" by The Carter Family. Beca is the main character in the film and a new student at Barden University.
