Entertainment Weekly reports that Emily Browning (The Uninvited, Lemony Snicket’s A Series of Unfortunate Events) will replace Amanda Seyfried in director Zack Snyder’s Sucker Punch at Warner Bros. Pictures.

Seyfried was set to play the lead role of Babydoll, but had to drop out due to scheduling conflicts with the fourth season of HBO’s “Big Love.” In the film, Babydoll 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.

Vanessa Hudgens, Abbie Cornish, Evan Rachel Wood and Emma Stone co-star. Sucker Punch is scheduled for an October 8, 2010 release.
