The Day the Earth Caught Fire is a British science fiction disaster film starring Edward Judd, Leo McKern and Janet Munro. It was directed by Val Guest and released in 1961, and is one of the classic apocalyptic films of its era. The film opened at the Odeon Marble Arch in London on 23 November 1961.

The film, which was partly made on location in London and Brighton, used matte painting to create images of abandoned cities and desolate landscapes. The production also featured the real Daily Express, even using the paper's own headquarters, the Daily Express Building in Fleet Street and featuring Arthur Christiansen as the Express editor, a job he had held in real life.
