Fresh off her success as the sunshine-loving mother in "The Kids Are All Right," Julianne Moore is going back to her darker roots.

The ginger beauty has been cast alongside Jeff Bridges in "The Seventh Son," a horror flick about a young boy training to be an exorcist in the 1700s who runs into trouble when he's tricked into releasing the most evil witch in the world.


The film is an adaptation of the first book in the trilogy "The Wardstone Chronicles," which are part of Joseph Delaney's young adult series "The Last Apprentice."

Moore will play "Mother Malkin," the most sinister of all of the witches who use blood magic, Bloody Disgusting reports.

Bridges will take on the role of the exorcist master Gregory, also known as "The Spook."

There has been somewhat of a rotating cast on this flick. Offers were originally out to it-boy-du-jour Alex Pettyfer and Academy Award-nominee Jennifer Lawrence—neither of whom will be joining now.

But we're pretty certain Moore and Bridges can hold their own.

Production is slated to begin September 13 in Vancouver, assuming no more of the stars disappear.
