This early film by Georges Méliès shows him playing with the medium by creating an amusing encounter with the Devil himself in a castle where he tries to scare the two guards. One flees, but the other manages to find a cross and drive out the Devil. It is quite fascinating, although most are done with simple trickery and it's sometimes pretty chaotic. The Devil was a character that very often appeared in the early films, usually as a trickster and usually also afraid of the cross. Because of the magical aspects, the appearance of a witch, and imps, a bat(hinting at early vampire movie), the topic falls out of the Christian fantasy realm a bit, but it shows how interconnected all things supernatural are.
