I think
Emmy Rossum did a fantastic job of both acting and singing in Phantom of the Opera released last year. a classically trained opera singer, she also shows great potential as an actress, she was in this year's
Poseidon but the scrip didn't allow her to show her range or craft at all . she's classy and seems a natural in front of the camera. she gets my vote.
