Zack Snyder lines up 'Sucker' cast

Seyfried, Hudgens, Cornish, Wood, Stone in talks

As the clock clicks towards the opening of "Watchmen" on Friday, Zack Snyder is beginning to put together an all-female cast for his next project, "Sucker Punch."

Amanda Seyfried in negotiations to topline the project, while Vanessa Hudgens, Abbie Cornish, Evan Rachel Wood and Emma Stone are in talks to star in the action fantasy, which Snyder is directing. Snyder is also producing with his Cruel & Unusual Films partner and wife Deborah Snyder.

Set in the 1950s, "Punch" follows a girl 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.

Snyder, who co-wrote the script with Steve Shibuya, has described the fantasy world as " 'Alice in Wonderland' with machine guns," blending such elements as dragons, B-52 bombers and brothels.

Seyfried would play Babydoll, the institutionalized girl.

If deals are completed, the rest would play Seyfried's fellow inmates who also travel into the alternate reality. Hudgens would play a character named Blondie, Cornish would play Sweet Pea, Wood would play Rocket and Stone would play Amber.

The shooting schedule is still being worked out.

Wesley Coller of Cruel and Unusual exec produces.

Seyfried, repped by Innovative Artists, starred as Meryl Streep's daughter in "Mamma Mia!" and is currently shooting Atom Egoyan's "Chloe." She next stars with Megan Fox in "Jennifer's Body."

Hudgens, repped by WMA and Untitled, is best known for her work in the "High School Musical" franchise while CAA-repped Cornish's credits include "Stop-Loss" and "Elizabeth: The Golden Age.

Stone, repped by Endeavor and Raw Talent, appeared in "Superbad" and is shooting "Zombieland."
