9. Anna Kendrick
After the release of Pitch Perfect, everyone and their maiden auntie knew that Anna Kendrick is a singer. But I doubt they know exactly how long she's been doing it for. She was a Tony nominee she was 13 years old, the second youngest nominee in Tony history, for her performance in High Society. Back in 2003, she made her film debut in Camp, a low budget indie that has a special place in the heart of every theatre geek in the world. She played Fritzi, a mild-mannered girl who turns out to be a little more intense than everyone bargained for. Why is a teenager singing The Ladies Who Lunch, a song written and really only appropriate for middle-aged women? Because that's how it works at theatre camp.
