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: When Glinda says, "Let the joyous news be spread" the bridge and pond are behind her. In the next shot she's turned around almost facing the pond. (00:23:40)
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: 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.
Continuity mistake: The Tin Man starts chopping the Witch's door and it's not the same one we just saw three shots before. The wood is a different color and the dark metal brace has been polished in the close-up. (01:23:40)
Continuity mistake: The rope around the Scarecrow's neck is tied differently throughout the scene after he meets Dorothy. The rag around his hat is rearranged also. (00:34:50 - 00:36:20)
Continuity mistake: When the Tin Man, Scarecrow, Cowardly Lion and Dorothy are cornered in the witch's castle, the scarecrow grabs the Tin Man's axe and chops a rope, releasing the chandelier, which falls on the guards. In the next shot, however, as the witch is shrieking "seize them", the guards give chase with only 1 or 2 laying on the floor. (01:24:55)
Continuity mistake: After the Witch throws a fireball at the Scarecrow in the woods and disappears, Dorothy is holding Toto. But when it cuts to a closeup of her, it looks like her shoulders are extended. When it cuts back to the wide shot, she indeed has her arms around the Scarecrow and Tin Man, even though she never put Toto down. (00:46:55)
Continuity mistake: As the four go through the green doors to see the Wizard the hallway triples in length between shots. (01:08:40)
Continuity mistake: After Dorothy falls into the pig sty Zeke holds his left hand over the right side of his chest. In the next shot his hand is over the left side of his chest. (00:04:20)
Continuity mistake: When the Wizard says, "Pay no attention to that man behind the curtain" he pulls the curtain closed and Toto's not there. In the next shot Toto's tied to the curtain again. (01:28:35)
Continuity mistake: When Dorothy first meets the scarecrow, there is a patch of grass in front of the field the scarecrow is in. On the grass there's two beds of flowers. The flowers change colors from when Dorothy meets the Scarecrow, to when the Scarecrow starts his "If only I had a Brain" song. (00:33:00 - 00:35:30)
Continuity mistake: During the storm the farm hands let the horses go and Dorothy runs to the back of the house as the wind blows directly in her face. If you look closely a large wood plank is sent sliding on the road, in the wrong direction into the wind. (00:15:50)
Continuity mistake: Glinda says to Dorothy, "I'm afraid you've made a rather a bad enemy of the Wicked Witch of the WestÂ…" and the mayor of the Munchkin city walks up from behind them. In the next shot he re-approaches them from the left. (00:31:00)
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)
Suggested correction: The "several seconds later" between his axe being taken and him having it back is a 25-second scene of the Scarecrow being pulled apart, and Dorothy and Toto being taken away. There was plenty of time for the Tin Man to retrieve his axe. Also, when we see the Tin Man with his axe again, there are still many flying monkeys on the ground, so it's possible that the flying monkey who took his axe didn't just immediately fly away with it.
Continuity mistake: When the Lion is singing about being King of the Forest, the Tin Man breaks a flower pot to "crown" him. Pay close attention, as the break marks on the pot change. In one shot there's a big jagged edge sticking up (obviously longer than the others) and in the next shot most of the edges are even.
Continuity mistake: When Dorothy first meets the Scarecrow there are no pumpkins on the left side of the Yellow Brick Road. Later when he starts to dance pumpkins have been added. (00:33:55 - 00:36:50)
Continuity mistake: Before Dorothy leaves Munchkinland she has a blue flower in her basket. She never touches the basket but as she dances out of town it's not there. (00:32:55)
Continuity mistake: Near the end of the movie, when Dorothy is saying good-bye to the Scarecrow, he is looking at Dorothy and begins to wave good-bye. In the next shot, his head is down and he lifts it slowly and begins to wave. (01:38:30)
Continuity mistake: As the Munchkins send Dorothy off singing "We're off to see the Wizard" the red coated guard is hanging out of his booth as he waves his sword. In the next shot he's inside the booth tapping time with his sword. (00:33:30)
