While looking up something else on YouTube, I came across Santa Claus, the world's first Christmas movie! This British silent film, a little over a minute long, was made in 1898 and was directed by George Albert Smith, a "stage hypnotist, psychic, magic lantern lecturer, Fellow of the Royal Astronomical Society, inventor" and noted film pioneer. It was considered a technical marvel in its time and definitely worth a watch.
Michael Brooke of BFI National Archive reports that the movie had "considerable technical ambition and accomplishment for its period," and that it "uses pioneering visual effects in its depiction of a visit from St. Nicholas." He also writes that it is "believed to be the cinema's earliest known example of parallel action and, when coupled with double-exposure techniques that Smith had already demonstrated in the same year's The Mesmerist (1898) and Photographing a Ghost (1898), the result is one of the most visually and conceptually sophisticated British films made up to then."
In this picture you see two children being placed in bed by a maid, lights are then shut off. Santa Claus enters the room from the fireplace and proceeds to trim the tree. He then fills the stockings that were previously hung on the mantle by the children. After walking backward and surveying his work, he suddenly darts at the fireplace and disappears up the chimney. This film surprises everyone and leaves them to wonder how old St. Nicholas disappears.
