The Red Spectre (1907, dir. Segundo de Chomón, Ferdinand Zecca)
In the film, a demonic magician performs a series of magic tricks, including trapping miniaturized people in bottles (the scene above is online here).
The film was shot in black-and-white, and colors were later applied using stencils, a mechanical process that replaced the more labor intensive hand-tinting.
Most early movie theaters had only one projector so “etiquette slides” were used to divert the audience while reels were being changed. These glass slides often featured lighthearted instructions for proper behavior while viewing a film.

A silent film studio in action - relatively simple, three-sided sets could be built side by side to make maximum use of the space, with two or more films shooting simultaneously.
