Jessica Biel is in talks to lasso up as Wonder Woman in Warner Bros.' all-star superhero film "Justice League of America."

Potential deal marks the first piece of casting to emerge from the DC Comics-based ensemble project, which is expected to feature Superman, Batman, the Flash and Aquaman in addition to Wonder Woman.

George Miller boarded the bigscreen adaptation last week as helmer.

Biel is filming the indie drama "Powder Blue," which wraps in October, opposite Forest Whitaker. That leaves room on the actress' schedule for "Justice," which Warner is fast-tracking as a project before any potential strikes. However, the film's likelihood hinges on the studio's ability to assemble a cast of superheroes in a small window of time. Christian Bale and Brandon Routh -- Warner's reigning Batman and Superman, respectively -- are not expected to join the production.

The studio declined comment, saying that it prefers to announce an entire cast rather than piecemeal deals.

"Justice League," which is penned by Kieran and Michele Mulroney, could help ramp up a Wonder Woman spinoff, which has long been in development at the studio, with Joel Silver producing.

Biel's recent credits include "I Now Pronounce You Chuck and Larry" and "The Illusionist."
