The trailer for Zack Snyder‘s Sucker Punch has been released.

Watch it here below.

Also, six character posters were released, which you can see here below (click images for larger, full view).

The trailer is a shorter version of the footage that Snyder debuted this past weekend at the San Diego Comic-Con, which opened to sequences hauntingly backed by Led Zeppelin’s “When The Levee Breaks.” [Read SDCC 2010: Zack Snyder’s “˜Sucker Punch’ Panel for description of the extended footage.]

The extended footage was much more captivating than this trailer, which runs about 1 1/2 minutes, so if this doesn’t grab you right away, don’t give up on it just yet.

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.
