Jon Hamm stars as the sauve Don Draper in the brilliant AMC Series, Mad Men, to earn a regular crust, but has just added another movie role to his growing CV. Watchmen helmer Zack Snyder has signed Hamm to the cast of his currently-shooting film, action fantasy, Sucker Punch. The cast already consists of a beautiful bunch; Emily Browning, Carla Gugino, Jamie Chung, Jena Malone and Abbie Cornish, so the handsome actor can drink Sprite and stuff with them. All that's known about Hamm's character is that he is called, High Roller. In the film, Browning plays a girl who tries to escape the hospital before an impending lobotomy - it's set in the 50's. Love Hamm, Snyder and most of the cast so can't wait to see this one.
