Continuity mistake: During the tornado scene while she's in her bedroom, there is a small oval picture (which looks like Elvira Gulch) over the bed which ends up sideways. As she gets up to leave after the house lands, it's straight up. (00:19:15)
Continuity mistake: When the Scarecrow says, "Won't you take me with you?" the straw from his right hand touches Dorothy's hair, but in the next shot his hand isn't even close to her. (00:38:30)
Continuity mistake: Dorothy's house just went threw a cyclone with chairs turned over, windows blown out and pictures knocked off the walls. Yet her comforter stays neatly folded and doesn't move from the bed. It's also changed and now has a plaid design on it. (00:19:05)
Character mistake: When the munchkin soldiers first arrive, you can see that some of the munchkins in the front are not beating their chest at the same time. This also happens when the munchkins sing the "fa la la la la" song before the witch arrives. (00:24:25)
Suggested correction: That happens in real life too with real soldiers and live performing actors as much as they try to perfect it because they're human, not machines. Unless there's a rule in the film that a munchkin has to be perfect and can't make mistakes like that, not seeing why this is a movie mistake when this is something that happens in real life.
Continuity mistake: When Glinda walks up the steps to greet Dorothy and the rest the floor can be seen and it's quite dirty. Later when Dorothy taps her heels together the same floor has been cleaned and shined. (01:36:15 - 01:38:40)
Continuity mistake: Just before Aunt Em and the others go into the storm cellar there are two glass jugs on top of the shelf on the right of their back door. When we see the spot again a few seconds later as Dorothy stands there the jugs are gone. They're not on the floor either. (00:16:40)
Visible crew/equipment: The four run away from the guards and leave the tower where the Wicked Witch is eventually melted. If you look closely in the two long shots from above them, the Tin Man reflects the bright stage light that is placed below them at the first bend of the walkway, on top of the Witch's castle. (01:25:25)
Continuity mistake: The Lion holds the bug sprayer in the crook of his arm as they walk up to the sign in the Haunted Forest. In the next shot he's holding it in his hand. (01:13:10)
Continuity mistake: In the Haunted Forest, Toto comes to the Tin-man, Lion and Scarecrow, barking. In a wide shot he is standing on loads of leaves, then in a closeup, he's standing on hardly any leaves, but in the next wide shot, he's standing on lots of leaves again. (01:16:20)
Visible crew/equipment: After we first meet the three farmhands, Dorothy asks Zeke what to do about Miss Gulch. As he walks off to feed the pigs he steps into the camera's shadow. (00:03:20)
Continuity mistake: During the tornado scene at the farm Dorothy runs to the back of the house and the bench is turned over - when she returns the bench is upright .
Continuity mistake: As Glinda's bubble appears Dorothy walks off camera but we still see her standing there as her shadow is on the yellow brick road. When we first see Glinda Dorothy's shadow just disappears. (00:21:30)
Continuity mistake: As she talks to the Scarecrow, Dorothy says to Toto, "Wasn't he pointing the other way?". In several of the close up shots wind is blowing her hair around and in others it isn't. (00:34:30)
Continuity mistake: As the Wicked Witch walks over to her sister a rocking chair is protruding through the broken window. In the next shot the window frame disappears and it's not a rocking chair anymore that's protruding from the window. (00:29:45)
Continuity mistake: As the Wicked Witch says, "It's so kind of you to visit me in my loneliness" a red penknife is on the ledge to their left. In the next shot it disappears. (01:16:10)
Continuity mistake: Dorothy's basket has been moved without anyone going near it after the Wicked Witch leaves the roof top. (00:46:20 - 00:47:30)
Continuity mistake: As they dance out of the poppy field, the snow that is on them disappears between shots. (00:57:35)
Continuity mistake: In the scene where the Scarecrow comes down off the pole and onto the yellow brick road, some of his stuffing falls out. You can then see Dorothy pick it up and put it back in. After Dorothy agrees to take the Scarecrow with her and they begin to skip away, you can see the straw that Dorothy supposedly picked up and put back inside the Scarecrow on the road again. (00:37:45)
Continuity mistake: When the Scarecrow sings, " In trouble or in pain" Dorothy grabs him and is holding her basket with her left hand. In the next shot the basket is on her forearm. (00:36:55)
Continuity mistake: After the Wicked Witch leaves Munchkinland Dorothy is standing in front of Glinda one step below the top. In the next shot from behind she's two steps below Glinda. (00:30:55)
