This would be the first horror movie ever made. It was directed by the French Illusionist Georges Méliès and incorporates many little Gothic horror attributes we would later use in further horror movies. Especially the ones that would be made in the 20s and 30s and so forth. Here we have vampires, ghosts, skeletons, the devil, bats and a haunted house.
There's even a mechanism in defeating the devil which would become THE tool in vanquishing evil in future horror movies. Mainly it was the use of the cross to symbolize Christ which is consider to be a source for all good. So what better way to use a cross to keep away evil spirits. So simple and very important piece of horror movie history.
