If They Tried To Make This Into An Updated Movie
Wow, would it be a mess.
The waitresses would be combined, Germans would be merged together (Gruber would probably be a sight gag), Helga would be combined with the fellow in glasses.
The British airmen would be seen once, Maria with her 'listen very carefully' would appear at best twice, the British guy with the bad French accent might have about two appearances as well.
A plot might get rolling with the two British airmen and the fallen Madonna and make it work for a movie ending with the war, as the final episode did.
