1 other mistake
Directed by: Ben Sharpsteen
Starring: Clarence Nash, Pinto Colvig, Walt Disney, Elvia Allman
Continuity mistake: When Mickey Mouse's fire engine arrives at the scene of the fire, you can see there is nothing attached on the bell on the engine, but when we see the bell in the next shot, it has now has a small pulley on it.
Trivia: When the fire creatures dance on the piano keys, the tune they play is "Who's Afraid of the Big Bad Wolf?", which was featured in the 1933 Walt Disney cartoon "Three Little Pigs."
