When did animated characters begin appearing on film with live actors

The combination of animated characters and live actors in films can be traced back to the early 1900s. One of the earliest examples is the film "The Enchanted Drawing" (1900), created by J. Stuart Blackton, which features Blackton interacting with a cartoon character he draws on a chalkboard. Another important early film that combines live-action and animation is "Gertie the Dinosaur" (1914) by Winsor McCay, where McCay interacts with a cartoon dinosaur brought to life through animation. These early examples laid the foundation for the integration of animated characters and live actors in films.
