The Alice Comedies were another early animation project by Walt Disney. These silent shorts featured some very innovative animation and special effects. Contrary to popular belief, they were not based off of Alice In Wonderland. The shorts were instead based around a live-action girl named Alice who would fall asleep or get knocked out and would end up in an animated world in her dreams. It's the early Mickey Mouse, Minnie Mouse, Donald Duck, Goofy, and Pluto era. Various actresses played Alice throughout the shorts' production. The plot didn't have much in terms of substance, as the shorts were mainly created to show off animation as a medium.
Being silent shorts from the 1920s, many of these shorts (particularly the ones from late in its run) have gone missing. Some are completely missing, others only survive in fragments. Historians have put much effort into finding these shorts, with one popping up every few years or so.
