Burgeoning scream queen Mischa Barton (“The O.C.”) is set to star in the supernatural romance I Will Follow You Into the Dark. The pretty 25-year-old Brit will play a woman willing to die to be with the lover who helped her get over the trauma of losing both her parents suddenly.

The Castlight Pictures and Zero Gravity release is written and directed by some guy named Mark Robinson. Costars include the very sexy Leah Pipes (Sorority Row), Ryan Eggold (“90210”) and Jaz Martin (The Shattering).

Barton, who made her horror acting debut as a tween in the 1999 M. Night Shyamalan mind-blower The Sixth Sense, returned to the genre in 2009 with roles in the buried-alive frightener Walled In and the psycho-bitch thriller Homecoming.

She will next be seen in the cave-set survival indie Into the Darkness and Apartment 1303, a 3-D remake of Japanese filmmaker Ataru Oikawa’s creepy J-Horror of the same name.
