Maggie Smith says she'll watch Downton Abbey when it's all over, lest she become plagued with self-doubt. "It's frustrating, I always see things I want to do differently," she says on 60 Minutes. So far, she hasn't watched Downton at all, though she is "very pleased" with its reception and is of course proud of her work. Lots of actors don't watch their shows or movies — or at least a lot of them say they don't — but apparently Steve Kroft is amazed by this. So much incredulity, Steve Kroft!
