Director Zack Snyder and his cast of Sucker Punch, his follow-up to his successful Watchmen adaptation, was on hand for the Warner Bros panel at the 2010 San Diego Comic-Con.

Snyder noted that, with his co-writer, he’d been working on the story for 8 years. He was motivated by the desire to create an original property “not based on a breakfast cereal or superglue, or anything like that.”

He then introduced the panel which included Carla Gugino, Vanessa Hudgens, Jamie Chung, Jena Malone, and Emily Browning.

Browning plays Baby Doll, whose mother dies, and is placed by her father in an insane asylum to be lobotomized and needs to discover a way to escape, if only through the world inside her mind. Hudgens plays Blondie, who fires some of the biggest guns in the film. Malone plays Rocket, who rallies the troops toward the idea of escape. Chung plays Amber, who’s loyal to Baby Doll. Gugino plays Polish psychiatrist Dr. Gorski, a dominatrix/choreographer/madame-type.
