Vincent Price and William Castle is a marriage made in heaven as far as I'm concerned. They struck gold with House on Haunted Hill (1959) and followed it up later that year with The Tingler. Director William Castle knew how to entertain people on a budget. The Tingler is no exception. The script is tailor-made for the theater with audience interaction in the form of buzzers under some of the seats that corresponded with various parts of the film. It was Rocky Horror before there was a Rocky Horror, and Castle was determined to transcend the wall between what is happening on the screen and what is happening in the theater. He succeeded admirably.
Vincent Price is also the reason for his success. His performance in The Tingler is classic Prince who has a gift for making even ridiculous dialogue seem believable. He is spot on as Dr. Warren Chapin, a pathologist who is convinced that there is a creature that lives inside every one of us that is the cause of fear. Our screams keep it from growing out of control. [I know it sounds crazy but, somehow, Price makes it work.] The Tingler itself falls into the "so bad it's good" monster category. Like The Blob (1958) before it, The Tingler is cheesy but that's what makes it so good.
Don't miss this 1950's classic. It's fun from start to finish. I rented the DVD from the William Castle Collection through Netflix and the picture and sound were terrific.
