Unusually for a light-hearted comedy, the cast contains four horror movie icons: Basil Rathbone, Lon Chaney Jr., Vincent Price, and John Carradine.
Vincent Price lost credit for his performance as The Real Casanova when he was caught up in the Joseph McCarthy-era "Red Scare" hysteria that swept the US in the 1950s.
Second of three movies Lon Chaney Jr and Vincent Price appeared in together. The first was Abbott & Costello Meet Frankenstein (1948) and last The Haunted Palace (1963)
Lon Chaney Jr and Bob Hope had appeared in My Favorite Brunette (1947) together.
When a tablecloth catches onto Pippo during his dance with Elena, all the far-end plates and glass goblets adhere to the tablecloth, obviously glued. It's much funnier this way than a floor covered realistically in broken glass.
