Fox's upcoming thriller "The Exorcist" doesn't aim to retell the 1973 horror classic, but it does hope to capture the film's "primal power."

"There's no horror movie more revered than 'The Exorcist," Executive Producer Jeremy Slater explains in this new sneak peak. "It's the scariest horror movie ever made."

The new video builds on the trailer, revealed at last month's Comic-Con International in San Diego. The series is the story "of the possession of a normal American family, in the suburbs of Chicago, and the two priests who are brought in to try and save this one innocent victim."

The sneak peek is filled with equal portions of religious imagery and scary bits, which is exactly what Slater is aiming for with the new show. "If we can give a couple people some nightmares," he mused, "I'll go to bed a happy man."

Debuting Sept. 23 on Fox, "The Exorcist" stars Geena Davis, Alfonso Herrera, Ben Daniels and Alan Ruck.
