Madame Louise is a 1945 comedy play by the British writer Vernon Sylvaine.
It premiered at His Majesty's Theatre in Aberdeen and then went on to a long West End run at the Garrick Theatre, lasting for 410 performances between February 1945 and February 1946.
[1][2] The original cast included Robertson Hare, Alfred Drayton and Paul Demel.
In 1951 the play served as a loose basis for a film adaptation made at Walton Studios.
Neither of the original stars appeared in the film version, which was rewritten to suit different actors.
