From the late 1930s through the early 1940s, George Formby was Britain's most popular movie comic. With his enormous grin and his ever-present ukulele, he kept audiences chuckling with such low-brow slapstick films as Keep Your Seats Please (1936) and Keep Fit (1937). Formby also worked on the screenplays of some of his earlier films and in the early '40s occasionally produced films. For the 1940 film It's in the Air, Formby also wrote song lyrics. Formby started performing in childhood in the north of England. This led to his working on radio, where he gained a national audience.
