Rosario Dawson is in negotiations to star opposite Aaron Eckhart in Incarnate, a potential new horror franchise from Jason Blum's Blumhouse Productions.

Brad Peyton is directing the microbugdet pic, which tells of "an unconventional exorcist with the ability to tap into the subconscious of the possessed who meets his match when a 9-year-old boy is possessed by a demon from his past," according to Blumhouse.
