London Films Productions is a British film and television production company founded in 1932 by Alexander Korda and from 1936 based at Denham Film Studios in Buckinghamshire, near London. The company's productions included The Private Life of Henry VIII (1933), Things to Come (1936), Rembrandt (1936), and The Four Feathers (1939). The facility at Denham was taken over in 1939 by Rank and merged with Pinewood to form D & P Studios. The outbreak of war necessitated that The Thief of Bagdad (1940) be completed in California, although Korda's handful of American-made films still displayed Big Ben as their opening corporate logo.
