The Man Who Laughs is a 1928 American synchronized sound romantic drama film directed by the German Expressionist filmmaker Paul Leni. While the film has no audible dialog, it was released with a synchronized musical score with sound effects using both sound-on-disc and sound-on-film processes. The film is an adaptation of Victor Hugo's 1869 novel of the same name, and stars Mary Philbin as the blind Dea and Conrad Veidt as Gwynplaine. The film is known for the grotesque grin on the character Gwynplaine's face, which often leads it to be classified as a horror film. Film critic Roger Ebert stated "The Man Who Laughs is a melodrama, at times even a swashbuckler, but so steeped in expressionist gloom that it plays like a horror film."

Mary Loretta Philbin was an American film actress of the silent film era, who played Christine Daaé in the 1925 film The Phantom of the Opera opposite Lon Chaney, and Dea in The Man Who Laughs alongside Conrad Veidt.
