As the film started Gertie poked her head out of a cave, and McCay encouraged her to come forward. He reinforced the illusion with tricks such as tossing a cardboard apple at the screen, at which point he turned his back to the audience and pocketed the apple as it appeared in the film for Gertie to eat.Wikipedia
