How to Make a Monster

How to Make a Monster is a 1958 American horror film released in 1958 by American International Pictures (as a double feature with Teenage Cave Man). It was produced and written by Herman Cohen, and starred Gary Conway, Robert H. Harris, Paul Brinegar of "Rawhide", Morris Ankrum, Robert Shayne and John Ashley. It was directed by Herbert L. Strock. The film is a follow-up to both I Was a Teenage Werewolf and I Was a Teenage Frankenstein.
