This is Acca-fabulous! Maine's own Anna Kendrick was on The Late Late Show with James Corden on Friday after Corden was saying that he was the best a capella singer! So Kendrick, who starred in Pitch Perfect and Pitch Perfect 2 challenged Corden into a riff-off on stage. They were backed up by The Filharmonic.

If you like Pitch Perfect, you'll love this!
