Other mistake: The traveling camera used during the opening credits is not positioned correctly; it is tilted to the right, causing the whole scene to be crooked.
Other mistake: In the 1946 MGM film "Good News" - there is a minor flub in the last musical dance number -The Varsity Drag. About 131.13 into the film- a woman dancer wearing a pink dress - just to the left of the screen- stumbles forward and almost falls onto her face while dancing. They left this scene in for some reason. (01:31:10)
Other mistake: When Daffy is helping the guest to his room, he looks at his keys as to which one would open it. When he finds the right key, he somehow manages to open the door without unlocking it.
Other mistake: After the fade out, the "The End" board shows it as an "MGM Tom and Jerry Cartoon." The two stars were not in this short at all.
