Exorzist II - Der Ketzer

The original cast and crew of Der Exorzist (1973) were very much opposed to a sequel. William Friedkin and William Peter Blatty actually met to discuss ideas at one point, but when they failed to develop a suitable premise, they abandoned the project. Both Linda Blair and Ellen Burstyn turned down repeated offers by the studio, though Blair eventually agreed to return when presented with what she considered a good script. However, according to Blair, due to various rewrites the script ended up a total mess. By that point, however, she was contractually bound to a sequel, and unable to drop out of the project.

The institution where Regan receives treatment has glass offices in which you can see the patients and their counselors with the only privacy being offered is by audio. Glass rooms in actual institutions usually have blinds/ curtains to provide visual privacy.

Exorcist 2 exists in at least three versions. The original version was 117 minutes long and was recut by director John Boorman the day after the premiere into a 110 minutes version, the one released theatrically. Major differences include the addition of a recap of the events of the first film through narration and freeze frame. Using stock shots of Linda Blair from the first film for the climax (all new shots of Regan possessed were done by a double because Linda Blair refused to have the possession makeup done on her again) and an alternate ending where Richard Burton's character is killed (In the original version, he runs off with Regan to help her be a force of good). The European version is also purported to be different. For a long time, only the recut version of Exorcist 2 was available for TV, cable and on video. Recently, the original 117-minutes cut has found its way to video and recent TNT airings.
