Disappearing Pliers
Poster for The Lost World (1925)
You may have read that King King (1933) was the first movie to use stop motion animation to create its creatures. That isn’t correct. The first one was the silent feature The Lost World (1925).
“While filming one of the stop-motion scenes, the cameraman spotted a pair of pliers in the picture. So as not to draw attention to them by having them suddenly disappear, he moved them a little at a time until they were out of the shot.”
