Other mistake: In the Todd-OA version, just before the song "Oklahoma." Gordon MacCrae puts his hand on the porch post and the post moves off the rail. He then pulls it back.
Continuity mistake: Lady is put in her bed and the master leaves the kitchen but he goes back in and puts a newspaper on the floor and leaves again but Lady gets out of her bed so the master comes back once more and puts her back in her bed but the newspaper on the floor has vanished.
Continuity mistake: Adelaide performs her first number and finds Nathan in her dressing room. There is a pink robe draped over the partition. Placement of this robe changes during the scene without being touched. (00:49:45 - 00:50:30)
Other mistake: The catapult on the battlements Jean uses to evict the castle guards is rather curious. First, there is neither a bow nor any torsion to 'power' the weapon, and secondly it just seems to cock itself, right after each shot. All that Jean does is pull the lever and none of her diminutive helpers stand by for any cocking work whenever the catapult arm is shown.
Continuity mistake: When Jervis returns Julie to her suite after a night of dancing, he picks up a morning paper, reads some excerpts from it, then says goodnight to her. As she opens the door, all he has in his hands is his boater, no newspaper, and in the following long shot, no paper is visible anywhere.
Continuity mistake: When the man is imitating the frog to the agent in the talent agency, he is initially holding his hat, and then throws his hands up into the air. When his hands come back down, the hat has disappeared.
