The Wizard of Oz (1939)

Revealing mistake: When the group is waiting to see the Wizard, the Lion sings the "If I Were King" song. The Tin Man grabs a flower pot and breaks it to make a crown. When the crown falls off the Lion's head later, it bounces around like plastic. (01:07:20)

Revealing mistake: When everyone is still in the poppy field, after the snowstorm, Dorothy says "Look. Emerald City is closer and prettier than ever." Look behind the Lion just as Dorothy says the word "City" and you'll see that the wire attached to his tail brushes over the top of some of the poppies, knocking the snow off. (00:57:15)

Audio problem: When Dorothy, Scarecrow, and Tinman are in the forest where they find Lion, the first time Dorothy says "Lions and tigers and bears, oh my" her mouth doesn't move at first but when the camera cuts to the next shot her mouth finishes the phrase. (00:48:45)

Continuity mistake: The Wicked Witch leaves Dorothy and runs to grab the hourglass. The mortar and pestle on the left of the hourglass disappear between shots. (01:17:50)

Revealing mistake: If you listen closely, during the singing of "We're Off To See The Wizard" by Dorothy, the Scarecrow and the Tin Man, you can recognise Buddy Ebsen's gravelly voice. He was the original Tin Man, but had a reaction to the makeup. They had already recorded the songs and it was too expensive to re-do it. (This film was WAY over budget and they couldn't waste time and money re-recording songs) (00:47:30)

Revealing mistake: When the foursome are granted permission to see the Wizard, they get up, link arms and proceed up the steps. You can see the wire that holds up the Lion's tail get caught in front of the Scarecrow's arm. He then lets it loose very carefully by unlinking his arm. (01:08:30)

Other mistake: When entering the Haunted Forest, the Scarecrow is carrying a pistol and a stick, the Lion has a bug sprayer and net, the Tin Man has a monkey wrench and his axe. But different scenes after that shows some items missing and then returning. I guess in the "Jitterbug" scene that was cut, they lost all those things but the axe. (01:13:15 - 01:16:00)

Continuity mistake: In the scene where Dorothy and the Lion are asleep in the poppy field as the snow is falling, there is at least one if not two close-up shots of Dorothy's face showing no snow falling around her at all. (00:56:35)

Continuity mistake: Dorothy's hair is long and almost straight in some shots and short and curly when the camera pans back to her. This happens throughout the movie.

Other mistake: When the Wicked Witch is giving the orders to the Nikko, the Head Winged Monkey, it shows his troops flying away before he's even finished receiving his orders. (01:14:40)

Continuity mistake: The blue shirted Lollipop Guilder comes from around the fallen house at the beginning of "Come Out Come Out," but he immediately appears emerging from a jet black manhole (with a black lip where the cover goes) in middle of the yellow brick in front of the house. (00:23:15)

Continuity mistake: At the end when the Wizard and Dorothy are in the balloon basket, the tie down ropes on the right side keep going from tied to untied and back to tied again through different shots. (01:34:55)

Revealing mistake: When the Tin Man breaks the flower pot for the Lion in the palace you can see the lines that it is supposed to break on. (01:00:55)

Continuity mistake: The pole that the Scarecrow was on moves out in front of the corn at the end of the scene as Dorothy and the Scarecrow run off and sing, "We're off to see the Wizard". (00:38:50)

Continuity mistake: When the Tin Man is attacked by six flying monkeys they take away his axe. Several seconds later he has it again. (01:15:20)

Continuity mistake: Dorothy throws water at the Wicked Witch not knowing it will melt her. If you look closely the witch is drenched when it hits her but in the next close up shot she doesn't have a drop of water on her. (01:26:20)

Continuity mistake: After both Dorothy and Scarecrow have oiled Tin Man's elbows, Dorothy pulls the Tin Man's arm down and we see her throw the apple that she's holding down behind him. In the next shot it reappears in her left hand. (00:41:55)

Continuity mistake: In the poppy field Dorothy falls down with the basket at her side. No one touches it but in the close-up it's by her head. (00:55:45)

Continuity mistake: When Dorothy is at the end of the movie confronting the Wizard about going home, since she killed the Witch, Toto goes over to the curtain and you can see him tied up to it as he opens it. Dorothy then goes over there and automatically has him in her arms - she didn't even need to bend down and pick Toto up. (01:28:55)

Continuity mistake: While with Professor Marvel, when Toto eats the sausage and Dorothy scolds him, she places her left arm on the basket. A frame later her arm is resting by her lap.
