Disney, Ub Iwerks, and their staff made the first Alice Comedy, a one-reel (ten-minute) short subject titled Alice's Wonderland, while still heading the failing Laugh-O-Gram Studio in Kansas City, Missouri.
Alice's Wonderland begins with Alice entering a cartoon studio to witness cartoons being created. Alice is amazed by what she sees: The cartoon characters come to life and play around. After heading to bed that night, she dreams of being in the cartoon world, welcomed by all of the characters. Alice plays with them until a group of lions break free from a cage and chase her.
This short helped set the stage for what was to come in the later Alice Comedies, as it established the world as a playful dream and also introduced the elements which would soon define the series.
