Los Monstruos del Terror (translation: The Monsters of Terror), also known as Dracula vs. Frankenstein and Assignment: Terror, is a 1969 Spanish-German-Italian horror film co-directed by Tulio Demicheli and Hugo Fregonese. (Fregonese quit midway through the production so the film was completed by Demicheli). Eberhard Meichsner was also credited as a director only in the British promotional material, but by all accounts he was not actually involved. It was followed in the series by the 1970 film The Fury of the Wolfman.
