Continuity: In the beginning while Dorothy is still on the farm, she walks along the pig pen fence and then falls in. When Bert Lahr picks her up out of there her dress is perfectly clean. (Time)

Visible crew/equipment: When the Wicked Witch scares the Munchkins in Munchkinland, where Dorothy lands, she disappears into a cloud of smoke she creates. But you can clearly see her sneak down into a trap door below. [As an aside to this entry, Margaret Hamilton was hospitalized for severe burns after a take of this shot (not the final one used) when there was a glitch in the timing of the explosion.] (Time)

Revealing: During the scene when Dorothy and Scarecrow are fighting with the trees, Scarecrow says "I'll show you how to get apples" and he gets hit by the apples. The very next scene if you quickly look at Dorothy's shoes, you can see that she is wearing black shoes, not her ruby slippers. (Time)

Continuity: During the sequence where Dorothy meets the Scarecrow, Dorothy's pigtails are first short (above her shoulders) and as the song progresses her hair gets longer (below her shoulders), then short, and then long again. (Time)

Revealing: 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. (Time)

Audio problem: At the very end of, "We Welcome You to Munchkin Land," at the very last 'fa la la la la laaaaaa' right before the Wicked Witch interrupts the song with her explosive arrival, you can hear someone scream before the explosion even occurs. (Time)

Visible crew/equipment: During the Lion's song of, "If I only had the nerve." You can see the cameraman's shadow pass over Dorothy, the Lion, and then the log on the side of the road. Watch carefully, it comes back. (Time)

Continuity: When the Witch melts, the broom is laying several inches from her dress. In the next shot, the broom is practically touching her dress. (Time)

Continuity: When the Wicked Witch scares the Scarecrow, Dorothy, and the Tin Man with fire, after the fire is thrown, not only is the Tin Man's funnel cap on backwards, everything is reversed. In order to keep the characters oriented from left to right correctly, they had to show the film from the wrong side, thus the buttons of the Scarecrow's jacket and everything else are on the wrong side. (Time)

Continuity: Immediately following the Tin Man's dance, Dorothy and the Scarecrow try to keep the Tin Man standing on his feet and clumsily shuffle over to a tree trunk where the Tin Man then sits. During this, the oil can in Dorothy's basket clearly falls out and on to the Yellow Brick Road. Dorothy doesn't pick it up but, in the very next shot, the oil can is back in the basket. (Time)

Continuity: In the scene at the Witch's castle, when the Scarecrow looks up at the candles hanging from the ceiling, the candles are lit, but when he chops the rope with the Tin Man's axe, and the shot is from above, showing the candles fall onto the men, they are not lit, but the next shot shows the candles on top of them and they are lit. (Time)

Continuity: Immediately after Dorothy throws the water onto the witch, there is a long shot of the group as they observe the Wicked Witch beginning to melt. In this shot you can see that the Scarecrow's arm is still on fire, yet nothing is done about it as they all focus on the Witch. In the next full shot of the Scarecrow the fire is completely out. (Time)

Continuity: When Scarecrow, Tin Man, and the Cowardly Lion are marching into the Wicked Witch's castle after taking the guards' uniforms, all three of them are shown holding the same types of spears as the guards, so when they go rescue Dorothy out of the locked room and Tin Man chops through the door with his axe, where did the axe come from? (Time)

Revealing: 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) (Time)

Continuity: In the scene where Dorothy meets the Scarecrow, there are no pumpkins on the ground while the Scarecrow is tied to the pole. After Dorothy gets him down, pumpkins are then everywhere behind the place that he fell. (Time)

Other: 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 insect scene that was cut, they lost all those things but the axe. (Time)

Visible crew/equipment: 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. (Time)

Continuity: 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. (Time)

Continuity: 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. (Time)

Continuity: 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. (Time)
