Vernon Sylvaine (1896–1957) was a British playwright and screenwriter. He is known for writing several popular stage farces. He began working in film in 1937 when his stage hit was turned into a film of the same title starring Robertson Hare and Alfred Drayton. Hare and Drayton starred in two further adaptations of his plays A Spot of Bother (1938) and Women Aren't Angels (1943). He adapted his own play for the 1943 comedy-thriller Warn That Man starring Gordon Harker, Basil Radford and Judy Kelly. His 1948 play One Wild Oat was turned into a 1951 film of the same title.
