It is! The other one I would have accepted was Disney's massive party in California. Snow White was the first animated feature length film. What is more it was the first animated film in color. It made so much money that Walt decided to throw huge parties for his staff. The party got so wild that people were getting drunk, jumping out of windows, and taking up all the hot tubs and pools in the clubs during the middle of the night. Walt was so embarrassed that he decided never to speak about that day again. It was also one of the events that made him start to look down on his staff (the other one was the massive union strike).
