Audio problem: When the man is in the Desert Inn in the film that is being shown at the theatre, he asks for the waiter, but when the film is being shown in reverse towards the end of the cartoon, no words are coming out when this happens.
Continuity mistake: When the goose is in the projection room towards the end of the cartoon, he pushes the leaver forward on the film speed and it is between "Slow" and "Fast." After we see what has happened to the film, we cut back to the projection room and the leaver is now between "Slow" and "Med."
