Did you know they made a movie out of it?

A D&D player won the lottery and decided to spend his winnings in an attempt to “bring Jack Chick's epic 1984 graphic novel / tract to film.” He got the rights from Jack Chick, ran a KickStarter (the lottery winnings were, after all, a mere $1000), and then he partnered with Zombie Orpheus Entertainment. They made a short film based off it and screened it at Gen Con back in 2014: https://en.m.wikipedia.org/wiki/Dark_Dungeons_(film)

Fun fact - it was not a parody. They took themselves seriously the whole time and stayed true to the source material. Worth a watch, IMO.
