A trailer for "The Exorcist: Martyrs" was unveiled Friday at New York Comic Con, with Scarlett Johansson taking on a role tracking a demonic killer. The film is directed by Mike Flanagan and functions as both a continuation and a reimagining of the long-running horror franchise.

Flanagan says the project draws heavily on "The Exorcist III" and describes it as the most unsettling project he has tackled. He told reporters the film was designed to feel dangerous and that it made him noticeably unsettled during production.
