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)
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)
Revealing mistake: Whenever Dorothy, the Scarecrow, the Tin Man, and the Lion go off into the horizon you can see the line on the floor of the sound stage where the fake horizon is and the scene cuts off right as the four get to that point. (00:57:35)
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)
Revealing mistake: In the scene where the Lion sings his "If I Were King" song just before visiting the Wizard, if you watch closely above his moving tail, there is a string holding up and moving around the Lion's tail. (01:04:15)
Revealing mistake: During some scenes, straw-stuffed Scarecrow's pant legs and his boots would sometimes have a gap that reveals the skin of Ray Bolger's leg. Two examples are, at Emerald City when Scarecrow places Lion's "cape" on him, and also when Dorothy and her friends are told the Wizard says to go away. (01:05:50 - 01:07:25)
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: After the doorman tells the four they can't go see the wizard he returns back into the palace and you can see his shadow where it shouldn't be against the painted backdrop wall inside the door on the left. (01:07:25)
Revealing mistake: When the guard tells Dorothy that she may not see the Wizard, Dorothy starts crying and tells a sob story about Auntie Em. Then, it shows the guard crying, but the tears aren't coming from his eyes. They're coming from above his eyebrows. (01:08:00)
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)
Revealing mistake: When they meet the Wizard for the first time, his big projected head doesn't reflect off the shiny floor, like everything else. (01:09:54)
Revealing mistake: You can see strings attached to the witches monkeys as they fly, and also strings from their bodies to their wings, to give the wings that flapping effect. (01:11:20)
Revealing mistake: The wires can be seen behind the Tin Man as he is lifted up in the Haunted Forest. (01:13:55)
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)
Revealing mistake: In the Haunted Forest, when the Tin Man is lifted up then lands back on the ground, at Tin Man's lower back you can see his white T-shirt tucked into his pants. (01:14:10)
Revealing mistake: In the scene of the Haunted Forest, when Dorothy is taken away by two of the flying monkeys, you can see that as she's kicking her legs in the air that they are mechanical. The kicking is very stiff and inhuman. (01:15:30)
Revealing mistake: When the Lion is pulling up the Tin Man with his tail on the way to the castle, you can see a square block inside the Lion's costume to hold the tail on. (01:20:00)
Revealing mistake: As the Tin Man holds on to the Lion's tail, the seam in the painted backdrop behind them is very visible going from left to right across the entire sky. (01:20:05)
Revealing mistake: As the Tin Man busts down the Witch's door with his ax if you look closely you'll see a slight edit in the film right before he takes his last swing. What they did was unlock the door before the last swing so it would open. You can see the dead bolt retracted as the door swings open. (01:23:50)
Revealing mistake: As the Wicked Witch throws the hour glass down at them the stone statue on the left of the monkey is shaking. (01:24:45)
Suggested correction: It's the monkey that is shaking, not the statue.
