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)
Continuity mistake: When they emerge from the woods before looking at the Emerald City, Toto runs up and stands on a rock with no tree anywhere near it. In the next shot from behind, a tree appears next to the rock. (00:54:35)
Continuity mistake: When the group emerges from the woods and is looking at the Emerald City, from the front Toto is about ten or fifteen feet to the left, standing on a rock. It then cuts to Dorothy for just a second, and then to a shot of the group from the back, and Toto is suddenly right behind them. (00:54:35)
Continuity mistake: When they first see the Emerald City Dorothy is holding the basket on her left arm. In the next shot it's in front of her in both hands. (00:54:40)
Continuity mistake: Dorothy raises her right arm and points at the horizon and cries, "There's Emerald City!", then lowers her arm. A shot later from the angle shot from behind, it's raised again and she's repeating all previous movements. (00:54:41)
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: In the poppy field when he starts to cry the tin man has a dark oily tear coming down his left eye that disappears in the next shot. (00:55:45)
Continuity mistake: As the Scarecrow yells for "help" in the poppy field, the Tin Man goes from holding the head of his axe to holding his head between shots. (00:56:15)
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)
Other mistake: In the poppy field the tin man has hardly any of that artificial snow on him because the asbestos used didn't stick to the metal like real snow. (00:56:55)
Continuity mistake: After she wakes up in the poppy field, Dorothy oils Tin Man's left arm which is stuck to his head. In the next shot his arm is lowered. (00:57:00)
Continuity mistake: As the Wicked Witch watches them in her crystal ball Dorothy is holding a hanky in her hand and the oil can is held by the Scarecrow. In the previous shot the oil can is in her hand. (00:57:00)
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)
Continuity mistake: As they all leave the poppy field the artificial snow has been neatly swept off the Yellow Brick road, and all traces of the snow on the ground are gone in the next shot. (00:57:30)
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)
Continuity mistake: As they dance out of the poppy field, the snow that is on them disappears between shots. (00:57:35)
Continuity mistake: As they all leave the poppy field the bricks on the Yellow Brick road run left to right. In the next shot the bricks are at a 90-degree angle, now running lengthwise. (00:57:35)
Visible crew/equipment: A large equipment shadow can be seen moving onto the Yellow Brick Road in the long shot as they dance off to Oz after leaving the poppy field. (00:57:40)
Visible crew/equipment: As the Wicked Witch prepares to leave for the Emerald City on her broomstick shadows appear on the painted wall depicting the sky behind her. (00:57:50)
Audio problem: As they all stand at the door to Oz, Dorothy reaches for the knocker and we hear the overdubbed knocking sound before she touches it. (00:58:45)
Suggested correction: The sound we hear before she starts knocking is of her grabbing the knocker, and it is right on time with when she grabs it. There is no audio mistake.
