The Hollywood Reporter carries word that Jamie Chung and Jena Malone will replace Emma Stone and Evan Rachel Wood in Sucker Punch, Zack Snyder’s upcoming film.

Set during the ‘50s, the film tells the story of a girl confined in a mental institution by her evil stepfather, who plans on having her lobotomized in five days.

While she’s in there, the girl imagines an alternate reality to hide from the pain and begins planning her escape, needing to steal five objects to help her get out.

Chung will play Amber, a country girl with a big heart. Emily Browning, Vanessa Hudgens and Abbie Cornish also star.
