The lake scenes were shot in sub-zero temperatures in November on the grounds of Leeds Castle. In order to prevent stars Dany Robin and John Fraser from catching pneumonia, their private caravans were filled with warmed bath towels, dressing gowns, slippers, hot-water bottles, several changes of clothes and large quantities of brandy. As well as this, both actors wore thermal underwear beneath their costumes, a requirement of the company insuring the film.
As John Fraser had learned to ride horses while stationed as a British Army commissioned officer in Germany, he filmed all of his own horse-riding stunts for the film. The only stunt he did not perform himself is the one where his character, Robert, pulls Ghislaine from a moving train and flings her on to his horse, as the company insuring the film refused to allow it.
The names of many of the characters were changed for this film version of the play, which transfers the setting from France to England.
The original Broadway production of "The Waltz of the Toreadors" by Jean Anouilh opened at the Coronet Theater in New York on January 17, 1957, ran for 132 performances and was nominated for the 1957 Tony Award for the Best Play.
