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.
Factual error: The Yonah in the film, portrayed by a 1920's-built replica of an 1830's vintage engine with a 4-2-0 wheel arrangement, is significantly different from the actual engine. The real life Yonah, built in 1849, had a 4-4-0 wheel arrangement just as the General and Texas engines. Also, the Yonah had a cowcatcher, a headlight, and sand box, all of which the engine in the film lacks.
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: Bradford's coat collar alternates between turned up and turned down throughout the scene outside the bowling alley. (00:15:00)
Continuity mistake: When the bulldozer is pushing the boat on the beach, the driver is initially dark skinned with a hat. Then next shot he is fair with no hat. Then back to dark skinned with no hat. (00:24:55)
Continuity mistake: When the Tartar princess Bortai is first shown, and throughout the first part of the scene when John Wayne and Pedro Armendáriz ride to check her out, she lies in a litter shrouded in shadows or perfectly lit, depending on the shot. (00:03:40)
Character mistake: When Henry Fonda is led to his cell, shot in a prison in Queens, a real inmate yells "What'd they get ya for, Henry?"
Continuity mistake: After his meeting with Julia, Winston at home opens the drawer and in a close-up pulls the diary out from under a stack of papers which he lifted with his left hand. The angle changes, and his left hand is on the edge of the drawer, and not supporting the papers any more, nor any paper is visible. There's also a pen on the table that should have been visible before, but wasn't there. (00:36:25)
Continuity mistake: When Napoleon takes some snuff, he puts the box back on the map, but in the next shot the box is now on the table near Bugs.
Continuity mistake: When the Coyote paints the landscape when preparing his "Stop! Bridge Out!" trap, he takes away his three points of paint and hides behind the sign. But when he notices the Road Runner has ran through the landscape, there is no sign of the three pots.
Continuity mistake: During the opening conversation between Butcher and his lawyer, the shadows on Lon Chaney Jr. switch place depending on the angle - in the shots with the camera behind him, the bars cast a shadow on his neck and side of the head that is not there in the frontals. (00:01:30)
Continuity mistake: There is nothing on the far end of the table when Elmer Fudd arrives at the shoemaker's shop, but when Elmer takes out his magic wand, a blue book appears.
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.
Other mistake: When the title card is shown, the copyright year is shown as 'MCMXXXIV' (1934). It was released in 1956 (MCMLVI).
