It just so happened that my agent called and said, 'There's this movie 'Pitch Perfect.' Here are the sides.' I think I originally read for Bumper, because Donald didn't have much in the script, so I read all Bumper's lines. I beatboxed for them, because that's what my character was supposed to do. And then I was like, 'By the way, I rap.'
There's no experience like going down an empty freeway toward a hurricane and then looking in the opposite lane and seeing bumper-to-bumper traffic, people fleeing that scene. Or going to a toxic spill and seeing people go the other way. You talk yourself into thinking you're invincible in order to do that.
