Visible crew/equipment: When Mammy catches Scarlett trying on a pretty bonnet when she is supposed to be in mourning, when the camera pans wide to show the room, in the mirror on wall behind Scarlett you can see the shadow of the grip holding the mic above Scarlett.
Revealing mistake: After Frank Kennedy's death, Scarlett is drinking in her bedroom, when she spies Rhett arriving outside her window. She then races to the mirror to brush her hair. She does not actually touch her hair with the brush strokes, probably so as not to disturb her hair, which had been specially styled by hair and makeup staff.
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.
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.
Character mistake: Prior to the Scarlett's Pledge scenes, Mammy Informs Scarlett (while they're standing out side of Scarlett's father study door) "We ain't got nothing but radishes in the garden." The next scenes show Scarlett walking through the fence that surrounds the garden. walks up to where the radishes are growing, digs one up, wipes it off and starts to eat it. This actually is a carrot, not a radish.
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.
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.
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.
