Produced by British government agencies in October 1940, London Can Take It was intended for release in the then-neutral United States to help drum-up support for Britain in the Second World War. The film profiles a day in the life of Londoners during the Blitz - the regular German bombing raids on British towns and cities which lasted from September 1940 to May 1941.
American war correspondent Quentin Reynolds narrated the film, focusing on the people of London and their ability to come together in the face of adversity. The film proved to be successful in the US, where it was distributed in cinemas by Warner Brothers. A shorter version of the film, entitled Britain Can Take It, was released in the UK.
