Audio problem: During the Tea Party scene, the Mad Hatter and March Hare ask Alice to tell her story. After the Mad Hatter says "And when you come to the end, stop!" audio follows of the voice director saying "great," leftover from the original recording. (00:45:40)
Visible crew/equipment: The furry suits the "mole men" are wearing clearly show the zippers up the back when one of them is going down a well.
Continuity mistake: In the flashback scene where Dustin Hoffman is in the hotel bathroom on the floor, he puts a coffee mug on the toilet, then the view switches and when it comes back the mug is gone, never to be seen again.
Continuity mistake: When the Japanese ship is about to be torpedoed, there are no numbers or letters on its side. In the next shot, when the ship explodes, a large white "265" is visible on the port side of the ship.
Continuity mistake: At the end of the film when all the women are dressed up after making clothes out of tablecloths, you can see the Italian woman riding in the front of the wagon. The shot changes and she's riding on the side looking at all the men and smiling. The shot changes again and she's back to the front.
Revealing mistake: When the boat is supposedly surrounded by a swarm of flies, they're really just relatively few flies trapped between two panes of glass in front of the camera lens. Evidence: whenever the camera moves, the "swarm" moves with it against the background, and you can even see some of the insects walking on the surface of the glass.
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".
Factual error: When Bruno is on his way to Union Station, he's heading on a bridge away from the Lincoln Memorial, which means he's leaving Washington D.C. for Arlington, Virginia, or in other words, he's going the wrong way.
Visible crew/equipment: When Gort picks up Patricia Neal next to the flying saucer, you can see cables leading down to her body to keep her hoisted. (01:20:15)
Visible crew/equipment: When the airplane flies over the area where the saucer skidded in and became buried in the ice, you can see the equipment used to clear the snow and smooth out the ice (at the narrow end of the ice). You can also see the tracks from the machine criss-crossing the circular portion from the aerial shots. (00:16:20)
Visible crew/equipment: Towards the the end, when Scrooge wakes up in his bedroom on Christmas day and is elated to know he is still alive, he goes over and looks in the mirror twice. Both times you can see someone in the mirror reflection in the background, possibly holding a script.
Continuity mistake: Alice Tripp is wearing different shoes when she starts walking home from the movie with George Eastman than she is when they are close to where she lives.
Continuity mistake: When the quake starts, Joyce Hendron runs to the arms of David Randall for protection. Ten seconds later, she again runs again to his arms. (00:41:55)
Factual error: John Wayne's squadron lands on Guadacanal as part of the "Cactus Air Force" in August 1942. However, they are flying F6F-3 Hellcats, which were not available, even to the Navy, until the middle of 1943. To top it off, they are painted in a late-war camouflage scheme with late-war markings.
Continuity mistake: When the giant is fighting the bull, in the long shots the bulls horns are white, but in the closeups, they're black.
Continuity mistake: When Hill disturbs Michael Corland at the table, he holds a piece of paper. The paper swaps hands between shots. (00:07:05)
Factual error: All of the Lydia's lieutenants are wearing epauletes on their left shoulders.only lieutenant commanders were permitted to wear one on the left shoulder, while the right shoulder was reserved for captains of less than 3 years' seniority.
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.
Revealing mistake: When Captain Quincy Wyatt interrogates a captive Seminole Native American by threatening him with a poisonous snake, the native is safe because there is a protective piece of glass between him and the snake. The snake's reflection is quite obvious on the glass panel. (01:14:40)
Revealing mistake: When The Indians launch their final attack (towards the end of the film), on a old outpost held by a small group of soldiers, Ward Bond is hit by a arrow which enters the right side of his chest. In the next shot you see Gregory Peck removing the arrow from the left side of Ward Bond's chest.
