Revealing mistake: After Frank Kennedy's death Scarlett is sitting in her room, "mourning" and drinking. When she hears Rhett's carriage she goes to the window. In this moment you see shadows, either from crew members or equipment, cast through the room, especially visible on the bottle on the table. There is also some funny shift of the backdrop outside the window. (00:55:35)
Continuity mistake: When Gerald O'Hara comes back from his afternoon ride he meets Scarlett in the fields. In the middle of the conversation, while they are walking along, the formerly bright sky all of a sudden turns to a dusky red, and Scarlett has a new hairdo that covers her ears. (00:11:20)
Factual error: When Atlanta is in chaos, there is a shot of a fire engine rushing down the street. Two shots later is a wide shot of the street with a giant red and white radio tower visible in the distance.
Continuity mistake: In the scene where Bonnie and Rhett have just arrived back from London, Bonnie runs up the stairs to greet her Mom, arms flying all over the place. In the next shot, Bonnie is holding the kitten that Rhett bought her.
Continuity mistake: When Scarlett is attacked in the woods, Big Sam drives her carriage out of danger. When the scene cuts to a far shot of the carriage driving through the woods, Big Sam is no longer with her. She is driving it by herself.
Suggested correction: Big Sam quickly dispatches Scarlett's attacker (potential rapist in the book) and Scarlett grabs the reins to just get out of there as fast as she can. Big Sam continues to handle the attacker. Then, Big Sam runs after the carriage, calling out to Scarlett.
Continuity mistake: When Scarlett shoots the Yankee intruder her bun is tied into a hairnet. When she searches his body and drags him away the net covers most of her head. (00:06:40)
Continuity mistake: When Scarlett talks to Ashley about eloping to Mexico at some point she turns away from him. This move is seen from two angles, where in one her scarf covers one shoulder, in the other both. (00:18:15)
Continuity mistake: When Rhett visits Scarlett after Frank Kennedy's death she keeps weeping into her handkerchief. But all of a sudden there is no handkerchief and she is wiping her nose with her hands. (00:57:55)
Suggested correction: Scarlett puts her handkerchief down to gargle with cologne. Then she goes downstairs with the hanky near her mouth to hide her boozy smell. She has opportunity to put it down again when she is seated telling Rhett she is afraid she'll go to hell. She is so upset she wipes her nose with her wrist as she does several times in the film, as Rhett observes at the end when she has no "handkerchief."
Continuity mistake: When Scarlett is being attacked on the bridge by the two thugs Big Sam comes and saves her. He throws one of the guys into the water, which all of a sudden has developed from a mere trickle to a remarkable river. (00:41:40)
Continuity mistake: When Rhett picks up Melanie from her bed to take her out of Atlanta he is not wearing a hat, but in the next shot it is on his head. (01:19:35)
Continuity mistake: When Scarlett's father comes home to announce that the war is over Melanie is standing on the stairs with empty hands. When we see her next a moment later she is carrying her baby. (00:09:15)
Continuity mistake: When Scarlett sees Frank Kennedy while she's working in the hospital, there is something on the left side of Frank's face in the close up shot of him. In the next shot that shows Scarlett and Frank, it is no longer there. (01:03:55)
Continuity mistake: When Rhett pours Mammy a drink on the day of Bonnie's birth he has a cigar in his mouth. When the camera angle changes he is holding the cigar in the hand that holds the glass. (01:06:35)
Factual error: Almost every crock in the background in this movie was made after 1920. I also saw clear, machine made jars. The automatic bottle machine was invented in 1901. Canning jars were crudely made and rarely ever clear in the 1860's.
Revealing mistake: When Scarlett runs out of the Wilkes's house calling for Rhett after Melanie dies, she bumps into a pillar that supposedly helps support the house/porch. The pillar wriggles quite violently at her touch, revealing it as a simple stage prop and not part of the house.
Continuity mistake: When Scarlett is flirting with the Tarleton twins dogs and horses in the background appear and disappear in a very discontinuous way. (00:07:35)
Suggested correction: Animals are not stationary, so they are bound to move. Also, if you watch it again, you will see some of the dogs running across the yard in front of Scarlett and the twins.
Continuity mistake: At the beginning of part 2 Scarlett walks by her sisters who are working in the field, carrying two water buckets. They start arguing, and Scarlett slaps Suellen, without any indication that she had put the buckets down. In the next shot we see her bending forward to pick up the buckets again. (00:03:10)
Continuity mistake: When Uncle Peter is chasing Aunt Pittipat's last rooster the poor creature passes by the same stack of wood twice in successive shots. (00:51:25)
Revealing mistake: There is a very short scene in the second half of the film where Mrs Meade and Dolly Merriweather are sitting at a tea table gossiping about Scarlett's behaviour. There is a teapot in the middle of the table, and Dolly Merriweather is sitting behind it. Yet the teapot is casting a shadow on the wall and Mrs. Merriweather isn't.
Continuity mistake: When the protagonists drive through the burning, abandoned Atlanta, a few looters are after the horse. Rhett knocks down one of them while the buggy is still moving, and in the next shot they are back at the spot where they were before being attacked. (01:20:00)
