“The Exorcism” (*1/2 out of four) was a misbegotten trifle about an actor (Russell Crowe) who begins exhibiting otherworldly symptoms and strange behaviors while filming a horror movie and some wonder whether he’s backslid back into addiction or if he’s been possessed. Crowe is slumming here in (incredibly) his second exorcist movie in a year but it’s just as blah and dull as that one. Director Joshua Miller is the son of Jason Miller from “The Exorcist” which spawned countless imitations like these. Filmed in 2019 and should have rotted on the shelf until it went to Hell.
