This one escaped the orbit of it's film (so did Pure Imagination, but not to the same degree)
If it comes to musicals there are quite a few songs that individually are better known / loved than the film they're from. I think more people may well know "If I Were a Rich Man" than have seen Fiddler on the Roof. Into operas that's even more true (who can say without googling what opera "Nessun Dorma" is from?) and then into quite a few Gilbert and Sullivan songs, the "Galop Infernal" from Orpheus in the Underworld by Offenbach (who even cares that it's not called The Can-Can) and eg. Mendelsohn's "Wedding March" from his A Midsummer Night's Dream.
I could go on but who needs it?
