Internet speculation suggests Angelina Jolie, Zoe Saldana and Sigourney Weaver could also be involved - though there's no evidence to support claims they may have been approached about roles.
But before casting can begin, Lerner is on the hunt for a female director for the film, penned by Legally Blonde scribes Karen McCullah Lutz and Kirsten Smith.

"The action movie will be spectacular — and in nothing inferior to the three male movies of the The Expendables," he said.
"There will be battles, special and visual effects and stunts — the spectacle will be equivalent to what Sylvester Stallone, Arnold Schwarzenegger, Jason Statham, Harrison Ford, Mel Gibson, Bruce Willis and Jean-Claude Van Damme have done.
"Two excellent screenwriters are already working on the picture. Now we are in search of a female director."
Shooting for the film, thought to be set in Dubai, is expected to start next year ready for release in 2015.
