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, a Hungarian Jewish émigré and England’s first and only movie mogul, Alexander Korda, signed Churchill up as a screenwriter and historical advisor. It was the start of a unique collaboration as Churchill provided script notes for Korda’s productions and penned an epic screenplay. When war broke out, their partnership took on national importance. These two establishment outsiders shared a common view of cinema’s propagandistic potential, which they skilfully exploited to turn the tide of history.
