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 designed to feel dangerous and that it made him deeply uneasy during production.
