Obscure comics from the 30's

[MonkeyGoat]

I can only think of a few movies based off, now, not too popular comics from the 20's, 30's, and 40's. Like the Shadow, and the Phantom.

What are some other movies like these? And what comics are they based off of?

Darkman, The Crow, League of Extrordinary Gentleman, Hellboy, Alien vs. Predator
