Madame Louise (also titled "The Madame Gambles"), is a 1951 British comedy film directed by Maclean Rogers and produced by Ernest G. Roy and starring Richard Hearne, Petula Clark, Garry Marsh and Richard Gale. It is loosely based on the 1945 play Madame Louise by Vernon Sylvaine, which had featured Alfred Drayton and Robertson Hare, but was extensively reworked to suit the different stars of the film production.
