Segundo de Chomón made "The Magic Mirror" and it's a very simple story (given it's only two minutes long) but technically a difficult film to make. It consists of a woman sitting in front of her magic mirror. When she sprays her atomizer, various women appear in the mirror and move about. Later, she makes the same thing happen on her jewelry...women appearing on it.
To achieve this effect, the filmmaker had to film the women and cut out the film and painstakingly insert it on the mirror or jewels. I've seen this done a few times and often it's shaky or inserted poorly, but not here. Well made for 1908.
