I have no idea, but it does have a feel very like film noir.

Do you happen to know if there is a generic term for the mood or atmosphere meant to be conveyed in the musical passage at 3:14, you know that kind of “Laura”-like theme (Think Charlie Parker’s version), as it is applied to visuals and mood?

We have the term “film noir” for old postwar detective movies, and there must be a term for that pre-beatnick urban “hepcat” vibe that was featured in so many late ’40s early ’50s films.

The scene you put up reminds me of a move scene with Fred Astaire in it, where he squat walks into a dive populated by jazz addicts and encounters another black haired femme fatale in a sheath dress. Now she was something.

There has got to be a simple name for that geometric, semi-abstract, jazz influenced urban downbeat postwar … idiom or motif.

I know—it’s an astounding moment.

And he does it while expressing something, too—impetuousness, yearning.

For accomplished dancers like that, how many hours of rehearsal, and how many takes, would they need to almost flawlessly perform a complex 6 minute dance like that? (And how many times do you think they kicked each in the head and/or the nethers until they got the timing down?)

And how seemingly effortlessly he carried her up those steps, like she weighed nothing. Dancers like that have to be superb athletes, don’t they?

My favorite with Gene Kelly was “Singin’ in the Rain.”
