Audio problem: When Ashley leaves the house to go to the train station after his Christmas furlough, there is a shot of Scarlett at the window, watching him walk down the path. We hear her say, "When the war's over, Ashley. When the war's over", but visually, her mouth movements do not correspond to what she is saying, at all.
Continuity mistake: After Frank Kennedy's death Scarlett is drinking in her bedroom. She takes his picture, which is standing on the dressing table, and turns it on its face. In one close-up shot this picture is placed on a piece of lace, in all others not. When she finally leaves the room the picture is gone completely, and also all other things on the dresswing table are rearranged. (00:55:20)
Continuity mistake: Scarlett, Melanie, and Mrs. Meade leave the hospital when Belle Watling approaches them to donate some money. Throughout the scene the three women are standing close to each other, but when Belle drives off Scarlett is standing by herself even though the camera does a scan around her. (00:59:00)
Continuity mistake: When Aunt Pittipat leaves Atlanta Scarlett and Dr. Meade are standing in the walkway to the house and talking. The moment the aunt drives off Scarlett is standing all by herself (and loudly cursing Melanie and her baby). (01:07:30)
Continuity mistake: In the scene where Bonnie dies, Scarlett is sitting down drinking a cup of tea. She puts the cup on the table and stands up. When we see the next shot from behind, the table is clearly visible and the cup is gone.
Continuity mistake: In the scene where Scarlett shoots the Yankee deserter, look at the large window at the top of the staircase. Not only is the glass strangely opaque, but there is the silouhette of a tree being cast on it from a tree which is obviously directly outside the window. When Melanie opens the window to call out to Suellen and Carreen, the tree is not only about 15 feet from the window, its also significantly shorter than you would expect from its shadow. In fact, it comes nowhere near as far as the window ledge, let alone the window itself.
Revealing mistake: When Rhett picks up newborn Bonnie from her bassinet, you can see that he picks up a doll, not a real baby.
Continuity mistake: Regarding the iconic pull-back shot of the depot, showing hundreds of dead and dying soldiers lying about the train tracks: later that night, everyone escapes by driving through this same area as train cars burn and explosions go off. What happened to all those dead and dying soldiers?
Continuity mistake: The morning that Rhett leaves for London, he tells Scarlett to get Bonnie's things packed right away. Scarlett pushes herself up into a sitting position on the bed with her arms, but in the very next shot, she's laying back against the pillows with her arms crossed. Then she pushes herself up again.
Continuity mistake: When Scarlett is talking to Melanie before she dies, Melanie's "widow's peak" is obviously painted on.
Continuity mistake: In the scene where Gerald gets on his horse to chase after Jonas Wilkerson, Suellen and Carreen run outside to see what is going on. The door is left open when they come out, but in the next shot that shows Scarlett yelling for Gerald to come back, Suellen and Carreen are no longer outside and the door is closed.
