Let me tell you, I feel terrible because I still haven't seen one single episode of "Mad Men," but right now, I just don't have the freaking time. I promise it's on my list though. Anyway, "Mad Men" star Jon Hamm has now joined Zack Snyder's upcoming action adventure "Sucker Punch," this according to the Hollywood Reporter.

Hamm joins the already cast Emily Browning, Vanessa Hudgens, Jamie Chung, Jena Malone, Abbie Cornish and Carla Gugino. The flick is set in the '50s and centers on a girl locked inside a mental institution. During her stay there, she imagines an alternative reality in which she plans her escape...

No word on what Hamm's character will do, but he will be named High Roller. Okay, I can roll with that. Hamm, who also appeared in "The Day the Earth Stood Still," has recently signed on to star in Ben Affleck's "The Town," the big-screen adaptation of Chuck Hogan's novel "The Prince of Thieves."
