Previous Post Quote: Corben did a live-action Den as some sort of college film, right? Before he did the comic? Has it ever been released anywhere? Too bad all of the comics didn't get a supplemental feature on a DVD or Blu-Ray, even as ROM features. Voila! https://www.heavymetal.com/news/richard-corben-den-neverwhere-film-1968/ This character actually appears in the comic as "Uncle Den."

That's pretty good for what it is. I'm not clear if Corben did all the animation himself or had help. He seemed to have something of a crew. In a way it felt like an early video game, with weapons appearing and disappearing.
