Night Train to Munich is a 1940 British thriller film directed by Carol Reed and starring Margaret Lockwood and Rex Harrison. Written by Sidney Gilliat and Frank Launder, based on the 1939 short story Report on a Fugitive by Gordon Wellesley, the film is about an inventor and his daughter who are kidnapped by the Gestapo after the Nazis march into Prague in the prelude to the Second World War. A British secret service agent follows them, disguised as a senior German army officer pretending to woo the daughter over to the Nazi cause.

Charters and Caldicott started out as two supporting characters in the 1938 Alfred Hitchcock film The Lady Vanishes. The pair of cricket-obsessed characters were played by Naunton Wayne and Basil Radford. The characters were created by Frank Launder and Sidney Gilliat. The duo became very popular and were used as recurring characters in subsequent films and in BBC Radio productions. Charters and Caldicott have also been played by other actors, and they eventually had their own BBC television series.
