Revealing mistake: As they exit the Tin Man's scene singing, "We're off to see the Wizard", a bird stretching its wings is casting a shadow on the painted sound stage wall slightly to the right of the house, which reveals it to be a fake backdrop instead of an open area. (00:47:45)

????

Revealing mistake: When Dorothy runs to the back of the house during the storm a crewmember is moving the rocking chair in the room on the left. The wind never stops blowing, but the chair stops moving after it's left alone. (00:16:35)

????

Revealing mistake: The candles on the chandelier that fall on the guards are not real. If you look closely at them they're operated with gas. (01:24:50)

????

Revealing mistake: The Scarecrow tells Dorothy to, "just bend the nail down in the back and maybe I'll slip off" but what she actually does is pull a lever. (00:35:40)

????

Revealing mistake: After the Wicked Witch throws fire down at them the Scarecrow kicks the stump next to him and it moves several times. The one behind him also moves. (00:46:25)

????

Revealing mistake: The Wicked Witch throws her hour glass at them and it's guided down to the floor by a wire. If you look closely before it hits the floor sparks start up around it and after it hits it doesn't move or roll, but just sits there. (01:24:45)

????

Revealing mistake: The glass in Dorothy's bedroom windows don't break, they are removed from their frames as the scene progresses, and if you look at the reflections in them the windows are made of plastic. (00:18:45)

????

Revealing mistake: As the Wicked Witch throws the hour glass down at them the stone statue on the left of the monkey is shaking. (01:24:45)

????

Revealing mistake: As the Tin Man holds on to the Lion's tail, the seam in the painted backdrop behind them is very visible going from left to right across the entire sky. (01:20:05)

????

Revealing mistake: The wires can be seen behind the Tin Man as he is lifted up in the Haunted Forest. (01:13:55)

????

Revealing mistake: Dorothy's bedroom window flies open and the wires pulling it can be seen glistening on the middle right of the screen. (00:17:00)

????

Revealing mistake: As the Tin Man busts down the Witch's door with his ax if you look closely you'll see a slight edit in the film right before he takes his last swing. What they did was unlock the door before the last swing so it would open. You can see the dead bolt retracted as the door swings open. (01:23:50)

????

Revealing mistake: After the doorman tells the four they can't go see the wizard he returns back into the palace and you can see his shadow where it shouldn't be against the painted backdrop wall inside the door on the left. (01:07:25)

????

Revealing mistake: As the Wicked Witch chases the four yelling "Seize them," they run around what looks like a concrete pillar. If you look closely it's covered with cloth that moves as they run by. (01:25:00)
