- B-Team Sequel: The producers considered bringing back William Friedkin to direct.
- Completely Different Title: The Spanish distributor saw fit to rename Dominion as "The Exorcist: The Beginning - The Forbidden Version", clearly trying to create interest by implying it was refilmed for being too scary instead of too brainy.
- Creator Backlash: William Peter Blatty said that watching this film was his "most humiliating professional experience." In fact, he and Paul Schrader were nearly thrown out of the premiere for loudly laughing during the screening.
- Executive Meddling: Possibly the greatest example ever, as most examples entail the studio forcing changes and retools, not redoing the entire film from scratch after it is almost finished.
- The Other Darrin: James D'Arcy replaced Gabriel Mann as Father Francis from one movie to another. There were many other replacements, but their characters were renamed and retooled too instead of just recast.
- The Shelf of Movie Languishment: Dominion eventually got released one year after Harlin's version.
- Troubled Production:
- Initially, Paul Schrader aimed for a psychological horror film. The studio was insatisfied, though, as they wanted a less cerebral and more conventionally horrific product. They fired Schrader and brought Renny Harlin to make the film Bloodier and Gorier. However, after considering some re-shoots, they decided to remake the entire damn thing. Harlin recovered all the cast he could and worked a completely new film.
- After Harlin's version failed at its release, the studio tried to finish Dominion by themselves in order to release it for a second chance, but their editor advised them to bring Schrader again to do it personally instead of committing another butchery. Schrader was given very little money and time (he could not even prepare a proper soundtrack, so he had to throw together some pieces from Angelo Baladamenti working for free and some others from Dog Fashion Disco).
