Could the blood from a species of fish unchanged by evolution turn a dog into a deadly wolf, or transform an ordinary dragonfly into a giant monster? Ask college science professor Dr. Donald Blake (Arthur Franz), but you’ll have to do it when he himself is not devolving into a rampaging caveman. Joanna Moore, Judson Pratt, Nancy Walters, Troy Donahue co-star in this horror/sci-fi tale from "Creature from the Black Lagoon" director Jack Arnold. 77 min. Widescreen; Soundtrack: English; Subtitles: English.
