Watch FMovies. Winston Churchill understood the power of films, but the true extent of his use of cinema as a propaganda tool is rarely explored. In 1934, one of Britain's most celebrated film producers, Alexander Korda, signed Churchill up as a screenwriter and historical advisor. It was the start of a unique collaboration. Churchill provided script notes for Korda's productions and penned an epic screenplay. When war broke out, their collaboration took on national importance. Korda was sent on a mission to Hollywood to help bring America into the war, with positive results. With access to previously undiscovered documents, this film documentary examines that mission and a friendship that underpinned a unique, creative partnership.
