Exorcista III

A police lieutenant uncovers more than he bargained for as his investigation of a series of murders, which have all the hallmarks of the deceased 'Gemini' serial killer, lead him to question the patients of a psychiatric ward.

Although I actually enjoyed the second "Exorcist" film, most people consider it a stinker and like to pretend it never happened. For those people, this is the right film to watch. A great tale of possession, that follows rather directly (though belatedly) from the original.

George C. Scott adds a certain weight to any film. Just as he did for "The Changeling", he makes what could be a forgettable horror film into something really worthwhile. He is a vastly underrated actor.
