Continuity mistake: When the five ladies find the concession stand closed, one of them pulls out a flask. Another gets the cups from the concession stand and passes them out. They then make a toast and drink. They never poured the booze into the cups. (00:18:20)
Continuity mistake: When Steamboat Willie drives the forklift into the two girls' mouths, the forklift blades are wider when he drives towards them than when they show the backside of the plywood he pierces after killing them. The blades were much closer after they were killed. (00:37:04)
Continuity mistake: When Steamboat Willie grabs the firehose and sprays the people, the stream of water changes between shots. When they show Steamboat Willie holding the hose, the stream is weak and barely reaches about two feet from him. When they show the passengers, the stream is very strong and knocks them off their feet. (00:43:00 - 00:43:30)
