Query: A Disappointing Genre-Bender

"Black Friday" (1940) survives as a rarity in cinema history: the gangster-horror film. Unfortunately, the reteaming of Boris Karloff and Bela Lugosi was jettisoned during preproduction - leaving poor Bela with a minor supporting role and Boris playing second fiddle to Stanley Ridges (who delivers an excellent Jekyll and Hyde characterization originally intended for Karloff). Though "Black Friday" moves at a fairly good clip, it remains one of Universal's lesser thrillers.
