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: When Cary Grant and the insurance agent are walking through the flower market, the girl in the bright pink dress walks past them twice.
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: When they are on the back porch, watch the Coke bottle. The level of the liquid in the bottle goes down, then up, then down, etc.
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)
Visible crew/equipment: In the very first scene when the camera pans in to the butcher shop, you can clearly see the shadow of the cameraman on the lift.
Other mistake: At the beginning of the movie at the police station and the next morning at breakfast, it at least appears to be established that Grandma lives with Jim and his parents. After all, they had just moved from another city and Grandma was there early in the morning at breakfast time. However that's the last we see of her. She is never mentioned again nor is she there after Jim comes home from school or at anytime after the trouble starts. It would be unusual for someone to sleep through all that went on; but no one ever says anything about "being quite or we might wake Grandma up." After that scene at breakfast, she is forgotten.
Other mistake: While all the business signs in downtown Osaka are properly in Japanese, the local newspaper, The Osaka Times, is printed entirely in English.
Factual error: When Kitchener is shown inspecting Harry's old regiment, one group of African or Egyptian troops is shown to be wearing the Pattern 1914 Infantry Equipment, not made until 1914 at the earliest. Additionally, it has the 1918 modification to have two closing straps, so is over 20 years too late for the 1894 date at that point.
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.
