Visible crew/equipment: At the climax, when the creature escapes and begins throwing furniture around, you can clearly see the wires attached to the pieces of furniture.

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.

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.

Visible crew/equipment: When the monster supposedly falls into a pit behind the altar at the end of the film, look at the left side. The mat the actor lands on visibly bounces into view.

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.

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: The opening scene states the date as April 10th 1865, the day of the train station robbery. Siringo tells Vance at the school money-raising event that the robbery took place 8 weeks ago, but when Clint is buried at the end, his death is April 25th 1865, only 2 weeks after the robbery.

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).

Continuity mistake: When Cluck Trent is using his typewriter at the beginning of the short, you can see there is nothing by the machine, but when the camera closes in on Trent, a sign saying "Cluck Trent Reporter" appears.

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: Milly is on the balcony with Mr. Hanson. The sliding glass doors behind them are not fully open and the drapes are drawn well past the door opening. When Mr. Hanson stands up, the camera cuts for a closer shot and the sliding glass door is now fully open and the drape is drawn to the door opening. (00:56:00)

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: 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: Bradford's coat collar alternates between turned up and turned down throughout the scene outside the bowling alley. (00:15:00)

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 Yosemite Sam shoots Daffy in the face with his guns, Daffy drops his carrot on the floor. In the next shot, the carrot has gone.
