Whit Bissel also portrayed the Doctor that created the Teenage Werewolf, in that movie.
American International Pictures released this film to many drive-in theaters on a double bill with Blood of Dracula (1957) with the tag line: "Warning! Can You Take It? Fiendish! Frenzied! Frightening! It Will Haunt You For Days Afterwards!"
Gary Conway (Bob - Teenage Creature) also played the actor portraying the Teenage Creature in 1958's "How to Make a Monster."
The title of this movie perpetuates a common misconception. The original novel and the first movie clearly establish that "Frankenstein" is the name of the scientist, NOT the unnamed monster. Hence the title of this movie makes no sense as it implies that the protagonist is an adolescent mad scientist.
Early in the film Dr. Frankenstein mentions several times that he's in America on a visa. When it expires he will return to England. He's been in the US long enough to lose all traces of an English accent.
