In a new video (unearthed by io9), Wrightson reflects on his time spent designing creatures for Ghostbusters, contributing ideas for the Library Ghost and Gozer’s Terror Dogs.
Bernie Wrightson is a concept artist and comic-book artist who specialized in horror and worked with countless legends on films such as Heavy Metal and Swamp Thing.
When he gets to the Hell scenes, he admits that he was working from an early draft of the story, which would have shown off the Gates to Hell, and presumably would have followed the Ghostbusters down this Road to Hell, where they might have encountered even more demons.
