Based on a Gaston Leroux story?
There's a modern Italian thriller out there called "M.D.C. - Maschera di cera", translated into English as "Gaston Leroux' The Wax Mask". Reviews of this movie say that it _is_ based on a Gaston Leroux* story, titled either "Le masque de cire" or "The Wax Museum". However, I can't find any Leroux bibliography that mentions this, so I wonder if the producers or reviewers aren't full of it.
Has anyone heard of a wax museum story by Gaston Leroux? Did _he_ invent the crazed wax sculptor character?
