Following a poor critical and commercial reception for The Exorcist: Believer, Universal may need to cut their $400 million losses on the planned trilogy. The film, written and directed by Halloween trilogy director David Gordon Green, is a legacy sequel to the William Friedkin classic, in which a mother comes to believe that her 12-year-old daughter is possessed by a demonic entity. The Exorcist: Believer, in a similar move to Green’s 2018 Halloween, sidesteps every sequel in the Exorcist franchise, serving as a direct follow-up to the first film with legacy cast member Ellen Burstyn returning.
