If you’re holding your breath for the big-screen version of “Pride and Prejudice and Zombies,” you may want to exhale a bit. While the best-selling mash-up of Jane Austen with flesh-eating zombies is headed for theaters, actress Natalie Portman says the movie won’t begin filming before next year.

“We’ll probably be shooting next year, hopefully,” she tells MTV News. Portman has been cast in the lead role of the film and says she’s looking forward to the project.

“It’s a really, I think, clever mash-up between genres. These women only obsessing over marriage is such a zombie kind of behavior. It’s kind of a perfect collision of genres,” she says. “We just got a new draft from David O. Russell, who is adapting it and is going to direct it,” she said. “I’m such a big fan of his. ‘Flirting With Disaster’ is one of my favorite movies, and ‘Three Kings’ and pretty much everything he does is incredible.”
