Fritz Lang's only film made in France (at Fox's European division) after fleeing there from Nazi Germany. After this production Lang would emigrate to the United States, but it would be two years until his next film, Fury (1936).
In his 1939 book about his Mexican travels, "The Lawless Roads", Graham Greene relates how the Mexican audiences prepared to walk out on the film when two forbidding-looking angels appeared, but settled back down to watch it when they realized that Heaven was going to be depicted in a humorous way.
