Fame is the Spur is a 1947 British drama film directed by Roy Boulting. It stars Michael Redgrave, Rosamund John, Bernard Miles, David Tomlinson, Maurice Denham and Kenneth Griffith. Its plot involves a British politician who rises to power, abandoning on the way his radical views for more conservative ones. It is based on the 1940 novel Fame Is the Spur by Howard Spring, which was believed to be based on the career of the Labour Party politician Ramsay MacDonald.

John Edward Boulting and Roy Alfred Clarence Boulting, known collectively as the Boulting brothers, were English filmmakers and identical twins who became known for their series of satirical comedies in the 1950s and 1960s. They produced many of their films through their own production company, Charter Film Productions, which they founded in 1937.
