After watching this Batman action figure fanfilm, I could swear that I recognized the underscore music from somewhere, but can't put my finger on it. Likely an old noir or mystery film... perhaps from 1939?
Unrelated: The song during the dancing sequence is Jack Teagarden's "Stop Kicking My Heart Around" feat. Kitty Kallen (also from 1939) although, that hasn't helped me pin down the film.
I really love the musical underscore, and would love to find the original film it accompanied.
Anyone have any ideas?
