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

Flanagan says the project takes strong inspiration from "The Exorcist III" and describes it as the most frightening film of his career. He told reporters the film was built to unsettle audiences and that it made him wildly uncomfortable during production.
