The earliest surviving use of double exposure in a movie was GA Smith's (UK) Santa Claus (UK, 1898). George Albert Smith depicted a simple scene of two sleeping children, superimposing the arrival of Father Christmas in a circle in the same shot. GA Smith also used the technique in The Mesmerist and Photographing a Ghost (both UK, 1898) and had patented the technique the previous year.
