Other mistake: About two-thirds of the way in, Robert Young re-visits the 'scene of the crime'. While climbing up the steep bank from the ravine, he reaches the top and, and in a very short shot (a few seconds), his shadow is cast upon the painted background scenery.
Continuity mistake: When Dr. Sawyer is giving Kris the exam, during the part where Kris is doing the physical coordination test, we see Kris from Sawyer's point of view, and Sawyer is drumming his fingers. When the shot switches to Kris's, he is fingering his eyebrow. When it switches back, fingers drumming. Finally, when it switches back again, his hands are neatly folded in front of him.
Revealing mistake: Cary Grant shows off his ice skating moves but you can tell it's a stunt double. The double is a bit shorter than Grant. Also in the same sequence, the two other skaters have noticeable doubles as well.
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)
Continuity mistake: Pinkie sweeps all the glasses on top of the bar onto the floor, yet after he and his gang have gone we see broken glass on the bar top.
Continuity mistake: To show time has passed, the wooden fence on the beach deteriorates, but the top of the fence, with Anna Muir carved in it, was never anywhere near the water - it was way up inland, far away from the water's edge - but now it is in the water, waves washing over it.
Continuity mistake: A full school day passes from when Lulu is first at school to get her fishing pole and to when she returns after awakening from being knocked out. It even looks darker from time passing. But the shadow of the tree is exactly the same, when the moving of the sun would have changed that. (00:01:55 - 00:07:10)
Continuity mistake: In the scene where we see two pilots in the cockpit of a aircraft, the co-pilot has a fake moustache. The top lip appears to be coloured black.
Revealing mistake: When Joan Crawford shoots van Heflin, he reacts as if he was shot before the shot is fired.
Continuity mistake: After Tom is sobered up by water, you can see behind him there is a bottle of seltzer in the refrigerator, but when Jerry comes along with a chicken drumstick in the next shot, the bottle has disappeared.
Continuity mistake: There is an apple core on the floor when Tom starts putting covering it with flour, but when he has finished covering the floor, there is no sign of the apple core.
Continuity mistake: In the scene where Jeb shoots Prentice, we see Prentice with his right hand covering the wound just below the right rib cage. When Jeb carries him inside, Prentice's right hand is now covering the left side rib cage. (01:05:55 - 01:06:35)
Audio problem: When Bugs says to the kid, "Cut it out, kid! Somebody will get hurt!", his mouth doesn't move.
Continuity mistake: When the cat places the tiny canary on to the plate, the salt and pepper pots on the table change positions between shots, and the cabinets in the background disappear. He also has a knife and fork in his hands, but after the canary says he's been sick, we return to the cat and the knife and fork have disappeared.
Continuity mistake: Bongo the bear, riding in a car of the circus train, looks out the window. There are four vertical bars on the window - but when seen from outside the train, it has six bars.
Continuity mistake: When Robert Taylor escapes from the asylum, and is driving the second car he steals, the car is shown at least once with windshield wipers pivoting from above the windshield, then shown with the wipers pivoting from below the windshield. Clearly, these are two different cars. I think the studio borrowed wiper footage from the scene in which he is driving the first stolen car, to use at moments in the scene in which he is driving in the second car.
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.
Continuity mistake: Pearl is singing a song to mock her boss at the factory. She goes through the first lines about being too worn out "to play." With her feet on the work table, she puts her hand under her chin. In the background, a fellow seamstress is watching. In the next shot, her arms changed position, now crossed in contrast to the previous shot. (00:04:40)
Continuity mistake: When Jerry first becomes buff after drinking some of the milk and starts approaching Tom to beat him up, Tom sees a book and grabs it then hits Jerry. Before Tom grabs the book, it's yellow. When he grabs it, it's green.
Continuity mistake: Bob Hope asks to take a peek at the execution chamber. He peeps from the hole, nudging away the lid with his forehead, and turns away. The lid came to a complete stop, but in the next shot when Ronnie walks away here's the lid swaying again as if he had moved his head from the window just that moment. (00:02:25)
