Diabolik (a.k.a. Danger: Diabolik) is a 1968 Italian espionage thriller, directed by Mario Bava and starring American actor John Phillip Law and many actors/actresses who were familiar to Italian moviegoers. Though being an American, John Phillip Law was also fluent in Italian, which made him popular in that particular film market. Though the international title of the film was Diabolik (named after the titular character) it was re-titled by the distributor as Danger: Diabolik for its' release in the U.S. Theatrical market to enhance the 'adventure' aspect of the film, since the term 'diabolic' or 'diabolical' in American cinema marquees usually described Horror or Alfred Hitchcock style murder films. It is noteworthy that the campy nature of the film made it a target of the MST3K (Mystery Science Theatre 3000) treatment.
The following weapons were used in the film Diabolik:
Colt Detective Special
The first-generation Colt Detective Special is seen twice in the film. Gangster Valmont (Adolfo Celi) uses a nickel version to shoot dissenting members of his gang. Later, police officer Sergeant Danek (Mario Donen) while disguised as a waiter, uses a blued version to shoot at Diabolik.
Various characters use early-model Beretta M12 machine guns with wooden grips and folded stocks.
The M1A1 Thompson is used by several police officers and guards throughout the film.
MP40 SMGs are also seen in the film.
