24 Hours of a Woman's Life, also known as Affair in Monte Carlo, is a 1952 British romantic drama film directed by Victor Saville and starring Merle Oberon, Richard Todd and Leo Genn.

He was playing host to Linda, a young widow whom he knew well, and three other guests aboard his yacht anchored in Monte Carlo.

When he persuades her to visit the casino one night, she became irresistibly attracted to an unstable young man who became suicidal after losing all his money at roulette.

[5] Richard Todd wrote in his memoirs that although he loved filming in Monte Carlo "I realised quite early on... that this current movie was not going to break any records; the story was twee and slow-moving, and charming and beautifully-set though it was, gorgeous backgrounds are not the only requisite for a successful box-office picture.

"[7] TV Guide called the film a "poor sudser, although the background of the romantic Riviera and its fabulous casino provides some exotic interest.
