Director Carol Reed directed this light wartime tale of double agents and disguises. It's a rare balance of comedy and thriller that works on both levels. The stars are Margaret Lockwood, Rex Harrison, and Paul Henreid, but it's two of the supporting characters who are the main attraction. They have a strange backstory. In Alfred Hitchcock's The Lady Vanishes, two minor comic relief characters named Charters and Caldicott, unflappable English gentlemen who discuss cricket with the same gravity and importance as they do murder and espionage. They were so popular that the screenwriters started putting them in other films they wrote, including Night Train To Munich. Such was their cult following that they spawned their own comedy mystery TV show in 1985.
