Sir John Woolf (15 March 1913, London – 28 June 1999, London) and his brother James Woolf (2 March 1920, London – 30 May 1966) were British film producers. John and James founded the production companies Romulus Films and Remus Films, which were active during the 1950s and 1960s, and the distribution company Independent Film Distributors (known as IFD), which was active 1950–59 and handled the UK distribution of films such as The African Queen and Gift Horse, as well as several films made by their two production companies (such as Room at the Top).
John and James Woolf were the sons of the British producer C. M. Woolf (1879–1942), who was co-producer with Michael Balcon of two early Alfred Hitchcock films, Downhill (1927) and Easy Virtue (1928). Woolf senior, was a major figure at Gaumont British, and established General Film Distributors in 1937.
John and James were educated at Eton, while the older brother also attended Institut Montana, Switzerland. John was the sales manager of General Film Distributors until it was taken over by the Rank Organisation James worked for Columbia Pictures in the Hollywood publicity department. John Woolf served in World War II and was demobilised with the rank of major.
Their father died in 1942 and J. Arthur Rank became director of General Film Distributors and John returned from the Army as joint managing director. However, neither John or James enjoyed working for a large corporation. In 1948, they went to S.G. Warburg for financial backing for two new companies, Independent Film Distributors, and a production arm, Romulus Films. According to critic Ronald Bergan, "Their aims were ambitious: to produce artistically valuable and yet commercially viable films, whose subjects would be wider than the Little Englanderism of British pictures of the period, and featuring big stars." An obituarist of James Woolf stated that John "was the main financial brain and James primarily in charge of artistic policy."
