The Contessa's Secret (, ) is a 1954 French-Italian film starring Yvonne De Carlo as Virginia Oldoini, Countess of Castiglione.
De Carlo signed on for the film in late December 1953. The film would be the first starring a Hollywood actor to have been shot in French without an English version. It was originally called Castiglione and Raf Vallone and Georges Marchall were meant to co-star.
Filming had to be brought forward earlier than planned so De Carlo could make a film with Cornel Wilde.
The film was shot in France in March 1954. De Carlo did not enjoy working for the producers . "I was very much put out when they gave me a stand in for a French dialogue coach," she said. "I thought I deserved better than that, particularly as I studied day and night to perfect myself in the reading of the lines. That was only one of numerous irksome things which not only I but other people had to put up with in that French production."
She later claimed the film was the first time a Hollywood actress did the lead in a film for which there was no English language version. "It was a distinction that made me feel proud."
