For the unrelated 1985 novel by Kay Thorpe, see Dangerous Moonlight (novel).

Dangerous Moonlight (known as Suicide Squadron in the USA) was a 1941 British film, starring Anton Walbrook, and best known for its score written by Richard Addinsell with orchestrations by Roy Douglas, which includes the Warsaw Concerto. Among the costumes, the gowns were designed by Cecil Beaton.

The film's love-story plot revolves around the fictional composer of the Warsaw Concerto, a piano virtuoso and "shell-shocked" combat pilot, who meets an American War Correspondent in Warsaw, and later goes back from America to join the RAF in England to continue to fight against the Nazis World War II occupation of Poland. Walbrook was an accomplished amateur pianist, so his hands are seen playing in the film, however the music on the soundtrack is played by the professional pianist Louis Kentner. Kentner's involvement was initially uncredited, as he thought that being seen to be playing film music would not help his career. He changed his mind on seeing the film's success[1]).

The film is mentioned in the British television series Dad's Army episode Is There Honey Still for Tea?, an in-joke as John Laurie had starred in the film.
