Continuity mistake: At the witch's castle, the witch throws a sand timer to the floor from a banister, and it smashes in front of a large group of her guards. But in the next shot, when the candle chandelier lands on all the guards, you can see that the smashed timer has disappeared. (01:21:20)
Continuity mistake: When singing 'Ding Dong the Witch is Dead', in a wide shot, many Munchkins run up to Dorothy, in a big crowd right beside her. But in the next wide shot when the mayor is saying 'From now on you'll be history' the crowd has gone. (00:27:20)
Continuity mistake: After they put the green robe on the Cowardly Lion, the flowers in the three pots on the right are different that what we saw at the beginning of the scene. (01:05:50)
Continuity mistake: When Dorothy is talking to the Scarecrow for the first time, the Scarecrow moves further down his pole between close up shots. (00:34:35)
Revealing mistake: When Dorothy runs to the back of the house during the storm a crewmember is moving the rocking chair in the room on the left. The wind never stops blowing, but the chair stops moving after it's left alone. (00:16:35)
Visible crew/equipment: Dorothy walks around Munchkinland and when we first see the Munchkin's heads popping up the crew's shadow can be seen on the flowers to the right of the screen. (00:20:55)
Continuity mistake: The yellow brick road is made out of painted bricks. As they enter Oz it changes into shiny linoleum with grey grout marks painted on it. (00:59:25)
Revealing mistake: Soon after Dorothy, the Tin Man and the Scarecrow meet the Lion for the first time, they dance along the Yellow Brick Road, singing. As they disappear at the back of the set, their shadows can be seen on the backdrop, equally covering the trees and everything in between. DVD showing. (00:53:10)
Continuity mistake: In the section just after the Tin Man has been oiled, he drops his axe and starts dancing on the road. After the Witch throws the fire at the Scarecrow, the three of them start down the road to Oz, he has mysteriously picked up his axe. (00:42:45 - 00:47:30)
Revealing mistake: In the scene where Dorothy, Tin man, Lion and Scarecrow are in the haunted forest and are discussing whether or not to believe in spooks, Tin Man is lifted up into the air and then comes crashing to the ground. You can see his pants wrinkle up as he's trying to get up. Since when does tin wrinkle like that? (01:14:00)
Audio problem: After the Wicked Witch of the West is liquidated, the soldiers hail Dorothy. After Dorothy asks for the broom, they are heard hailing her again, but none of their mouths move. As the scene fades into the next one, the soldiers' mouths can be seen beginning to move to say the line. (01:27:20)
Continuity mistake: The characters change places from one shot to another as the Wizard gives the Tin Man his heart, etc.
Continuity mistake: The flower pot crown that falls from the Cowardly Lion's head goes from being behind the gang to by the right of them, with no-one touching it. (01:04:38 - 01:05:50)
Continuity mistake: In one of the most endearing scenes from one of the greatest movies of all times, nobody noticed that as Dorothy sings "Over the Rainbow" the haystack she's standing next to just materializes between shots. Later it disappears long before the twister reaches the house. If you watch the movie you'll see the exact spot where the haystack should be seen as Aunt Em gives Dorothy a cruller and says to her, "and find yourself a place where you won't get into any trouble". (00:07:25)
Continuity mistake: As the Tin Man chops open the Witch's door only one piece of wood has fallen off of it. In the next shot when Dorothy comes through there's much more rubble on the floor (in front of and behind the door) than there should be. (01:24:00)
Audio problem: The very last line of the scarecrows song "Life would be a ding-a-derry if I only had a brain" does not match with the scarecrow's mouth movements, probably because he's too busy concentrating on his dancing. (00:35:55)
Continuity mistake: As the Cowardly Lion chases him, Toto runs off the Yellow Brick road into the bushes twice. (00:50:15)
Suggested correction: He only runs into the bushes one time.
Visible crew/equipment: There are multiple fragmented reflections of studio lights on Dorothy's bedroom window, as it rips off due to the twister. (00:16:20)
Visible crew/equipment: As they enter the poppy field their shadows can be seen against the painted wall as they walk in front of a stage light just before and after they come into view. (00:54:20)
Visible crew/equipment: In the close-up when Dorothy sings, "With the thoughts you'd been thinking you could be another Lincoln, if you only had a brain" look closely and you can see the shadow of the camera man on the Scarecrow's arm. (00:36:55)
