Trivia

Jamie Lee Curtis was born exactly one week prior to the release of this movie, with both her parents, Tony Curtis and Janet Leigh, starring in it.

This is the fourth of five films husband and wife Tony Curtis and Janet Leigh starred in. In chronological order, they are: Houdini le grand magicien (1953), Le chevalier du roi (1954), Les Vikings (1958), this film, and Qui était donc cette dame? (1960).

Upon Tony Curtis and Janet Leigh starring in their first film together, Houdini le grand magicien (1953), there was a controversy who would get top billing. Leigh had more seniority, as she made her feature film debut in 1947, while Curtis (who had played bit parts and extras) finally made his in 1951. However, Leigh said that she would take second billing to Curtis in any picture they made together. Hence the reason Curtis gets billing over Leigh in this film.

Linda Cristal was the last primary cast member of this film to pass away (on June 27th, 2020).

This is the second of four films star Tony Curtis and director Blake Edwards made together. In order, they are: L'extravagant Mr Cory (1957), this film, Opération jupons (1959), and La Grande Course autour du monde (1965).
