Revealing mistake: 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.

Visible crew/equipment: When Dorothy walks out of her house in Munchkinland, shadows cast by the trees can be seen on the painted hills right behind them. (00:20:20)

Revealing mistake: 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.

Revealing mistake: When Toto reveals the Wizard by pulling the curtain aside, he doesn't use his mouth; the curtain is tied to the dog. Dorothy can even be seen later removing the rope.

Revealing mistake: 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. (00:33:40)

Character mistake: When Dorothy and the others enter the Haunted forest, the sign reads "Witches Castle One Mile." "Witches" is plural. To be grammatically correct, it should have said "Witch's Castle," if one witch, or "Witches' Castle" if more than one.
