 The stadium used for the football match, although supposed to be the  Stade Colombes in Paris, is actually in Budapest, Hungary. This is  because the producers had difficulty finding a large stadium without  floodlights, as floodlights at football stadiums were largely  unknown until well after WW2. The MTK stadium in Budapest was the  biggest one without lights (but at the same time structurally  similar to Continental stadiums that were around during WW2) that  they could find.
