'O.C.' Star Mischa Barton Lands Role In Voodoo Thriller

'Hexxx' revolves around a tombstone with mysterious powers.

Mischa Barton is heading to college.

No, it's not a new twist on "The O.C." or a real-life Olsen-twins-inspired effort, but rather the star's first lead role in a major movie. Barton has signed on to lead a pack of college students through a world of voodoo in "Hexxx."

"There's a legend of a tombstone in New Orleans that if you mark three Xs on it, your wishes will come true," explained Jennifer Klein, who is producing "Hexxx" through her Apartment 3B Productions. "I don't want to give anything else away."

Klein is tweaking the script now to be ready in May, when Barton wraps "The O.C." MGM will release the movie later in 2005 or early 2006.

"It's a good next step for [Mischa]," Klein said. "It's an 18-year-old college freshman who is a really strong-willed girl. It's a very strong character. She's not a wilted flower."

Barton has appeared in "Notting Hill" and "The Sixth Sense" (remember Haley Joel Osment's dead friend?), as well as several smaller films, but has yet to star in a major movie (see "Mischa Barton Of 'The O.C.': 17 Going On Famous").

The actress is following in the footsteps of "The O.C." stars Adam Brody and Benjamin McKenzie, who have been using their TV fame to land movie roles. Brody is set to star alongside Meg Ryan in "In the Land of Women," and he also has a small role in Brad Pitt and Angelina Jolie's upcoming "Mr. and Mrs. Smith." McKenzie just finished shooting an indie feature called "Junebug."

Klein, who was an associate producer on "Pearl Harbor," is also developing a movie with Lucy Liu, among other projects.
