Fifty-Fifty is a farce by H. F. Maltby, adapted from a French original, Azaïs, by Louis Verneuil and Georges Berr. It was the penultimate work of the series of Aldwych farces that ran nearly continuously at the Aldwych Theatre in London from 1923 to 1933. The play centres on the sudden rise of an impoverished music teacher to become manager of a grand casino.
The piece opened on 5 September 1932 and ran until 21 January 1933, a total of 161 performances.[1] A film adaptation was made in 1933 under the title Just My Luck.[2]
