A scene from F.W. Murnau’s masterpiece Faust (1926), where the demon Mephisto takes Faust on a flying tour of the world.
To fake this in the 1920s, the crew built a hidden iron platform in the studio to hold the actors, using massive fans to blow their capes and billowing glass wool to create the surrounding clouds. They then used double exposure to layer the actors over a moving, miniature model city, making it look like they were actually soaring over the mountains and rooftops.
