10 Horror Movie Mistakes Directors Refused To Fix Because The Acting Was Too Good

Watching The Exorcist is never usually a fun experience, so imagine how bad it must have been making the damn thing.

Of course, the opportunity to be part of one of horror's greatest institutions is nothing to sniff at, but the actors in the film had to endure some pretty frightening and disgusting stuff. Especially Jason Miller, the man who played Father Karras.

Tasked with removing the evil entity inside of little Regan MacNeil, Father Karras communes with the demon as the young girl acts as a conduit. During one famous scene, Pazuzu lures the man of the cloth into a false sense of security before spewing horrible green vomit directly into his godly visage.

Miller had been told that the fake spew, which was really coloured porridge, would hit him in the chest. However, when the cameras were rolling for real, the gloop was aimed a little higher.

The actor's reaction was completely genuinely, which was just one of the many ways the cast of this film were tortured in the name of art.

Still, the scene is pretty funny, so that more than makes up for the trauma... actually, no it doesn't.
