Continuity mistake: In the scene when Rhett is saying goodbye to Scarlett before he leaves her on the road to Tara alone, he throws his hat behind him onto the road and takes Scarlett into his arms. However, a few moments later, he picks the hat up from the fence at his side along with his coat.
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 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.
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: 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.
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.
