A trailer for "The Exorcist: Martyrs" made its debut 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 built to unsettle audiences and that it made him deeply uneasy during production.
