Underground is a 1928 British sound drama film directed by Anthony Asquith and starring Brian Aherne, Elissa Landi, Cyril McLaglen, and Norah Baring. While the film has no audible dialogue, it was released with a synchronized musical score with sound effects using both the sound-on-disc and sound-on-film process. The film examines the lives of ordinary Londoners and the romance between them, set on and around the London Underground.

The Film starts and ends with an Underground train coming into a station. It shows humorous scenes of people coping with the crowds on the underground train. It also has interesting shoots of London, from a bus, of the Thames from the top of a power station which appears to be Lots Road Power Station, a pub, and a shop. Has much to commend it for in terms of looking at London and its people in the 1920s The film has strong roles for the two leading women, while the men are more clichéd, one a villain and the other a blue-eyed, blond angel.

The narrative is very well directed, making it clear what is happening and what is being said, with minimal use of dialogue cards. Harassment of women and abuse of women are themes of the film.
