After watching the "Overlord" trailer and reflecting on my love of Wolfenstein, Hellboy and Indiana Jones, I'm really curious.

I'm sure that the Nazis were not really summoning demons or building supernatural superweapons. Neither is it likely that they were digging for Arks and Grails.

Is there any basis in fact though? Were Hitler and top Nazis interested in the occult or superstitious in any way?

I know that the trope of the Nazi Zombies originates pulp comics of the 30s and 40s. So does that mean there is no truth?
