Anna Kendrick is 'Pitch Perfect'

Anna Kendrick keeps it comfy in red sweat pants as she arrives at LAX Airport in Los Angeles on Friday evening (September 16).

The 26-year-old actress just returned from the 2011 Toronto International Film Festival where she premiered her new film, 50/50.

Anna is also in early negotiations for Pitch Perfect, THR reports.

The flick, which is based off of Mickey Rapkin‘s nonfiction book, centers on the romance between two members of dueling collegiate a capella teams. Anna would play the goth-like and rebellious lead who finds the vocal group to be an escape from her unhappy school life.
