Young Dr. Frankenstein (Wilder), a brain surgeon, inherits the family castle back in Transylvania. He's skittish about the family business, but when he learns his grandfather's secrets, he becomes obsessed with making his own monster. Wilder and monster Boyle make a memorable song-and-dance team to Irving Berlin's Puttin' on the Ritz, and Hackman's cameo as a blind man is inspired. Garr (What knockers! Oh, sank you!) is adorable as a fraulein, and Leachman (He's vass my--boyfriend!) is wonderfully scary. Wilder saves the creature with a switcheroo, in which the doctor ends up with a certain monster-sized body part. Hilarious parody.
