Trivia: Not really a mistake, given the need for drama in a war film, but the mission takes place the evening before D-Day, meaning the Allies had complete air supremacy, and knew the exact time, date and place of the meeting of the German officers, this mission would never have taken place. The brightly lit chateau would have been flattened by a squadron of heavy bombers. Lee Marvin, an experienced combat veteran, pointed this out to the producers and was told to keep his opinions to himself.
Trivia: During "Springtime for Hitler," film director Mel Brooks can be heard saying "Don't be stupid, be a smarty! Come and join the Nazi party!" He later dubbed the same line in the 2005 version.

Trivia: During the title sequence, as Millie is buying a pack of cigarettes from a vendor, her undergarment breaks. The vendor stares at her in surprise, and she does a slight curtsy and walks away.

Trivia: The movie went by quite a number of different titles: 'Dance Of The Vampires' (original UK title); 'The Fearless Vampire Killers, Or: Pardon Me, But Your Teeth Are In My Neck' (US title); 'Vampire Ball' or 'The Vampire Killers' (working titles).
