Visible crew/equipment: In the scene where George takes Samantha into the lounge room to lie down, as she reclines on the lounge you see the shadow of the boom microphone on the ceiling moving.
Factual error: Towards the middle of the movie when when the British submarine leaves port with the Man Who Never Was onboard, it is flying what appears to be an American flag. The flag is visible for about ten seconds and if you look closely, you can see the field of blue of the stars and stripes in the upper corner.
Suggested correction: The flag, as can be seen before submarine sails and then from a distance, is obviously the White Ensign.
Factual error: Two grave markers at the end, approximately one hour and 27 minutes into the film, have the date of November 7, 1889, on them. The script made it clear that the climactic gunfight between Glenn Ford and Broderick Crawford came on a Sunday. Ford was called out of church services, for example. According to The World Almanac and Book of Facts, November 7, 1889, was a Thursday, not a Sunday.
Continuity mistake: At the very end of the show when Marshall Cass Silver gets in the carriage with Sally, Sally enters first, sitting on the left and him on the right. When the next shot shows them riding off together in the carriage, they have switched sides.
Continuity mistake: When Luther Blair rescues Captain Larson from his cell towards the end of the film they are both shown exiting the cell with pistols drawn and ready. When the shot cuts to the corridor outside both their pistols have now disappeared from their hands.
Continuity mistake: When Frankie punches Barakov, pushing him through the window, not only do you see the wires lifting him, but it is obvious that the inside of the building is a studio set as not only does the window get broken, but also the wall above it is torn. The wall is obviously made of paper and the scenery outside the building is a painted backdrop. And when the angle changes to outside the building, only the window is broken but the wall is intact.
Factual error: As was the case in Buster Keaton's "The General" film, the General locomotive portrayed in the film more closely resembles the actual locomotive's 1893 appearance rather than its wartime appearance. As built, the General had three domes, an ankle bar on each side running the length of the engine, as well as the Western and Atlantic Railroad's then trademark strap-iron cowcatchers with horizontal slats. The engine was rebuilt in the 1870s, with the bars and third dome removed, and cowcatcher changed to the more conventional design seen in the film. The Radley Hunter Balloon stack the engine had was replaced with a diamond shaped one at this time, as the engine was converted to coal. The engine received a stack more closely resembling its original one in 1893.
Continuity mistake: In the scene where Van Gogh cuts his ear off, he smothers his right ear with a towel to stop the bleeding. As the movie continues, we notice that throughout the whole movie his left ear was the one missing not the right ear as initially portrayed.
Continuity mistake: In the scene where Robert Wagner and Buddy Ebsen are in a fox hole note the position of the bullets in their boxes. One lot is further away from the pole holding the shade canopy and in a closer shot it's now changed position and closer to the other bullets. The shot then changes again and the bullets are back to their original position as seen earlier. (01:19:25 - 01:20:50)
Continuity mistake: When the Coyote has put on his Batman outfit, you can see behind him there is a boulder and an empty box before he is about to jump. But we see the Coyote on top of the cliff in the next, the boulder and box are nowhere in sight.
Other mistake: When the title card is shown, the copyright year is shown as 'MCMXXXIV' (1934). It was released in 1956 (MCMLVI).
Other mistake: When Stupor Duck looks into the mirror and sees that the shoulder pads on his costume are positioned incorrectly, look at the mirror and you can see that the "S" on his costume is the right way round - it should be back to front.
Continuity mistake: When Foghorn Leghorn is relaxing in the barnyard, you can see there are two hens fanning him, but when a man on a bicycle arrives with a telegram, the hens with fans have disappeared.
Continuity mistake: When Milly and Burt walk into the kitchen there is a white bowl on top of the refrigerator. Later, when a distraught Burt leans against the refrigerator, the bowl has disappeared. (00:58:35 - 01:06:20)
Continuity mistake: When Robert Wagner falls, halfway up the mountain, Spencer Tracy's rope, which is attached to Wagner, runs through his hands, making them bleed, but, finally, he gets a grip and he pulls Wagner up. As we see Tracy's rope, as it slowly comes up, but there is no blood on it.
Continuity mistake: When we see Dorlock Holmes at his desk at the start of the cartoon, you can see that he is writing with the feather in his right hand, but in the next shot he is holding the feather with his left hand.
Continuity mistake: When Daffy (dressed as Bugs) is fishing at the pier, there is a can beside him that keeps disappearing and re-appearing between shots.
Continuity mistake: Just after Bader has been told he'll never fly again, he meets his girlfriend on a bridge. As they walk along the bridge, Bader is on the girl's left, but, in the long shot, Bader is now on the girl's right.
Continuity mistake: Bradford's coat collar alternates between turned up and turned down throughout the scene outside the bowling alley. (00:15:00)
Continuity mistake: When Elmer Fudd realises that some of the elves are missing, his elf helper steps forward and you can see behind him are the other elves. When Elmer says "What shoemaker?" we return to the elf and the other elves who were behind him have disappeared.
