A trailer for "The Exorcist: Martyrs" was unveiled Friday at New York Comic Con, with Scarlett Johansson cast as someone tracking a demonic killer. The film is directed by Mike Flanagan and acts as both a sequel and a reboot of the long-running horror franchise.

Flanagan says the project takes strong inspiration from "The Exorcist III" and describes it as the scariest thing he has ever made. He told reporters the film was designed to feel dangerous and that it made him wildly uncomfortable during production.
