Alfred Clark’s "The Execution of Mary, Queen of Scots" (1895) featured what was possibly the first ever edit within a film—and it was a cut in more ways than one. In order to simulate a decapitation, a hidden cut allowed the substitution of a dummy in the place of the (male) actor playing the queen. The effect was so horrific and realistic at the time that audience members reportedly believed that someone had really given her life for the part.
