I remember watching a film when I was a teenager that seemed to be set in a 1930s film noir kind of setting.
I think the main character was a private detective, who somehow got caught up in some kind of plot to bring some big malevolent supernatural force. I think he also had some kind of magic power, but can't remember what specifically.
I'm pretty sure I remember that there were zombies - from the voodoo tradition, not Romero-type undead zombies.
From what I remember of the production quality, it was produced in the late 80s or early 90s. I think it might have been a TV movie (maybe a pilot?).
I'd love to watch it again if I can find it.
