Fanny by Gaslight (US title – Man of Evil) is a 1944 British drama film, directed by Anthony Asquith and produced by Gainsborough Pictures, set in the 1870s and adapted from a 1940 novel by Michael Sadleir (also adapted as a 1981 TV serial). It was the second of its famous period-set "Gainsborough melodramas", following The Man in Grey (1943). Its US release was delayed for its breaking the Hays Purity Code and 17 minutes were removed.
