Miklós Rózsa - Prelude to the film Double Indemnity

For those who haven't seen this film, it is the platonic ideal of Film Noir.  Certainly director Billy Wilder thought so.  The music was controversial during the filming, with the studio's Music Director at loggerheads with composer Rózsa right up until the studio's Artistic Director heard it - and loved it.  Then everything was copacetic.

The music mined Franz Schubert's Unfinished Symphony for inspiration, which fit the Noir mood quite well.
