Leonardo Dicaprio recommended the movie in this idea, "Wouldn’t it be cool to do a Gothic twist on Red Riding Hood, with the wolf being a werewolf, and just have a cool, sexy romantic thriller?"
There is just one problem, Red Riding Hood is already Gothic. It was a story told in bars in the Gothic lands of Germany to the brothers Grimm. So its all Gothed up and ready to go without needing to mention a werewolf. Though that is a cool idea.
