Warner Bros has premiered a new poster for Zack Snyder’s upcoming action flick Sucker Punch. The movie is about a bunch of repressed girls who finally take control of their lives. They’re handing out ass-kickings and lollipops and they’re all out of lollipops. Over at Yahoo, they’ve debuted the new one sheet that exclaims, “You will be unprepared.” Be warned there’s violence waiting below…

This poster is nothing to write home about, but we feel that it gets the point across. The girls are front and center ready for battle, which is essentially what the film’s about. We also like the title design and we think it will look great in 3D, with the military planes and all.

Set in the 1950s, Sucker Punch follows Babydoll (Emily Browning) who is confined to a mental institution by her stepfather, who intends to have her lobotomized in five days. While there, she imagines an alternative reality to hide her from the pain, and in that world, she begins planning her escape, needing to steal five objects to help get her out before she is deflowered by a vile man. This trailer gives us a better idea of what those five things are.

Sucker Punch is scheduled to hit theaters on March 25, 2011.
