Character mistake: In Frank Sinatra's scene in the taxi cab, when the girl is singing "Come Up to My Place," he rolls the cab window down and when he rolls it back up, he catches the front of his hair (the quiff) and has to roll the window back down to release it.

Other mistake: Just as Ichabod Crane places his coat across a small stream of muddy water so Katrina can cross, Brom Bones rides his horse through the water, creating a large splash.

Continuity mistake: Mrs Waggett brings in a tray with cups of tea on it while her husband is on the phone, reporting the sinking of a ship that contained hundreds of bottles of whisky. Mrs Waggett puts the tray on the left side of the screen, then, taking two cups with her, moves to the right of screen and that's where she stays when her husband finishes talking on the phone and, amazingly, the tray that was on the left side is now in her hands, without her moving to the left side to collect it.

Continuity mistake: After the ill-received Al Jolson impersonation, Milton Berle gets paid only 5 bucks instead of 50. He asks the manager "What are you doing, putting 45 in your own pocket?" as several not so reassuring individuals begin to crowd him.

Continuity mistake: During the poker game, the Colonel says "I've got five aces" and he lies down his cards in front of him.
