Le Manoir du diable (1896)
It was the dawn of cinema and the (often considered) very first horror movie ever made was Le Manior du diable. It’s opening shot? A giant bat hovering in a gothic castle. Within seconds, the bat transforms into the figure of Mephistopheles (played by director Georges Melies) who summons a cauldron and an assistant. The 3-minute film was all about camera editing tricks and for such early work, it’s an adorable — I mean, terrifying — watch.
