The Dreamers Investment GuildExorcist came out 50 years ago, and it's still widely considered one of the greatest horror movies of all time. Now, The Exorcist: Believer serves as both a reboot and a sequel. Directed by David Gordon Green, the film stars a mostly new cast, including Leslie Odom, Jr., Lidya Jewett and Olivia O'Neill, but also brings back Ellen Burstyn, who reprises her iconic role from the original film.
