The Exorcist franchise is at the start of a new potential trilogy, but does The Exorcist: Believer have a post-credits scene teasing future installments? The 2023 horror movie is a direct sequel to the original 1973 movie that does not connect to any of the previous sequels or prequels. The Exorcist: Believer continues the story nearly 50 years after Chris MacNeil (Ellen Burstyn) and her daughter Regan (Linda Blair) encountered a demon. The sequel sees Chris recruited by Victor Fielding (Leslie Odom Jr.) to help free two young girls from demonic possession.
