Continuity mistake: At the detective agency, while Bud and Lou are talking to the murderer, the description of the murderer comes over the police radio, and it states "5 feet 11 inches, weighs 165, blue eyes, brown hair, last seen wearing a felt hat and dark borwn overcoat". Then 15 seconds later Bud says out loud, writing on a piece of paper the description "5 feet 10 inches, weight 165, blue eyes, sandy hair".
Continuity mistake: During the final dance number, Vera-Ellen's skirt alternates repeatedly between long and flowing and short and tight - perhaps to facilitate some of the dance moves.
Continuity mistake: Early on in the film Alec Guinness is travelling in the back of a van transporting gold bars to the bank. He spots what he believes is a suspicious car following and asks the driver to stop to check it out. The next shot shows the van stopping outside a row of buildings in a London street. The driver gets out to let Alec Guinness out of the van and they are now parked by a low wall with an open vista (probably one of the many bomb sites in London at the time) and no buildings.The next shot then shows the van outside the buildings again.
Continuity mistake: When the young man says "What's cooking?" to St. Peter at the beginning of the short, St. Peter is holding a feather in his right hand. In the next shot, the feather has disappeared.
Continuity mistake: In the overheard view of the dog grooming the cat, you can see there is nothing beside them, but in the next shot a blue ribbon suddenly appears.
Continuity mistake: At the beginning of the short, we see a wrestling match on the television and underneath the screen are two knobs; the left knob is between "Light" and "Dark" and the right knob is between "Vert." and "Hor." When the cat wakes up and sees a turkey advert on the television, all the words have disappeared.
