The Jon Hamm express continues to roll: The sexy, 37-year-old breakout star of Mad Men has been cast in Sucker Punch, a Warner Bros. action film that will be directed by 300‘s Zack Snyder.

The film is set in the 50s, ten years before the 60s-based Mad Men show Hamm stars in on AMC; it also stars Emily Browning, Vanessa Hudgens, Jamie Chung, Jena Malone, Abbie Cornish and Carla Gugino.

Sucker Punch hits theatres March 25, 2011; Mad Men airs on AMC Sundays at 10/9c.
