Is there any kind of direct mention anywhere, (like in an interview or something) or at least strong indirect evidence, that the striking similarities between aspects of The Chronicles of Riddick and Warhammer 40,000; such as, for example, between the Necromongers and the Imperium of Man, are deliberate to any degree? This is something that's been bugging me for years.
It's well-known, of course, that Vin Diesel played tabletop games, and that he had some creative control over the series, (in fact, I remember hearing an apocryphal story somewhere that the character of Riddick himself was based on a Drow character that Diesel had played in a long-running D&D campaign) so it's not that outlandish to try to make this connection, but is there any evidence beyond just speculation?
