Revealing: Throughout the movie, you can tell that if the main characters walking into the distance, the "faraway" landscape is a giant matte painting.

Continuity: You see a bird-monkey flying with Toto before he gets picked up.

Continuity: The Lollipop Guild teleports all over the scene. As Glinda departs, they are behind Dorothy. As Glinda's bubble rises, several Munchkins run to where she was and wave goodbye, yellow shirted Lollipop Guilder (Jerry Maren) among them. Cut to Dorothy and Jerry's still behind her.

Continuity: As the Wicked Witch is melting the peak of her hat stays intact. In the very next shot it has been flattened.

Plot hole: The Tin Man says he was frozen when "...I was chopping that tree... and right in the middle of a chop I rusted solid. I've been that way ever since." But when Dorothy and the Scarecrow find him, he's standing straight up with his legs together, looking straight ahead, with his axe held up with one hand. What kind of chopping position is that?

Continuity: At the start of the film when Dorothy comes running into the farm calling Aunt Em, Uncle Henry has just taken a chick out of a hat, and is placing it into an open coop. Yet when the shot changes his hand is instantly back in the hat taking out another chick.

Continuity: 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.

Other: As the Wizard is pulling his curtain closed, he says the famous, "Pay no attention to that man behind the curtain," in a loud, booming voice. But he's turned 180 degrees away from his microphone, which we see a second later needs to be right in front of his mouth to make the booming voice effect.

Continuity: In the scene where Dorothy and the Scarecrow first meet and oil the Tin Man, the leaves on the Tin Man's shoulders appear and disappear several times.

Continuity: When the Wicked Witch tells Nikko "throw that basket in the river and drown him" The basket with Toto in it moves from one shot to the other in its position to the hourglass.

Continuity: The Wicked Witch of the West's bilious green face colouring changes shades during the film. DVD showing.

Continuity: The strand of straw that the crow pecks from the Scarecrow's lapel was not there before, as shown by previous close-ups.

Continuity: The blue Lollipop Guilder scoots up to Dorothy with his hands in his pockets. In the next shot his thumbs are sticking out.

Continuity: The broom that Dorothy gives to the Wizard has never been on fire and the end has been trimmed neatly.

Continuity: The length of the bristles in the Witch's broom changes throughout the movie.

Revealing: As Dorothy is about to walk into the cyclarama (backdrop) as she leaves MunchkinLand, a Munchkin Soldier on the very far right is too far and becomes transparent with the matted-in flowers.

Continuity: When Dorothy and the Scarecrow find the Tin man and oil his mouth, between shots the leaves on the Tinman's shoulders change.

Revealing: When the doorman initially refuses to let Dorothy and friends into the Emerald City, they protest, saying the Good Witch of the North sent her; they show him the ruby slippers as proof. As the camera pans down to the slippers, look at the yellow brick road Dorothy is standing on - it is flat and looks as though it was simply painted.

Revealing: In the forest scene when they walk up to the warning sign, watch and you'll see the Scarecrow's stick bend like rubber.

Revealing: When the Wicked Witch throws the ball of fire at the Scarecrow, you see the Tin Man get down on his knees and take off his hat to put out the fire. If you look really closely, you can see several hairs on the Tin Man's head.
