Visible crew/equipment: Studio lights are seen reflected in Dorothy's bedroom window as it rips off due to the twister.

Revealing: In the scene where Dorothy, Tin man, Lion and Scarecrow are in the haunted forest and are discussing whether or not to believe in spooks, Tin Man is lifted up into the air and then comes crashing to the ground. You can see his pants wrinkle up as he's trying to get up. Since when does tin wrinkle like that?

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.

Continuity: When the scarecrow is singing, "If I Only had a Brain", as he dances around the flowers on the fence seem to disappear and then appear again.

Continuity: When the Lion is singing about being King of the Forest, the TinMan 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 scene most of the edges are even.

Continuity: 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.

Visible crew/equipment: As the door keeper tells them he will get them into the Wizard the camera shadow can be seen moving across the green door.

Continuity: The pole that the Scarecrow was on moves out in front of the corn at the end of the scene as Dorothy and the Scarecrow run off and sing, "We're off to see the Wizard".

Audio problem: In the poppy field the tin man says "this is terrible" but his lips don't match up with what he's saying.

Continuity: Before Dorothy walks on the pig sty, Uncle Henry can be seen on the far right side of the screen. He stops, stands there for about 10 seconds and then walks to the right. In the next shot he's gone.

Continuity: In the section just after the Tin Man has been oiled, he drops his axe and starts dancing on the road. After the Witch throws the fire at the Scarecrow, the three of them start down the road to Oz, he has mysteriously picked up his axe.

Continuity: 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.

Continuity: Throughout the film, if you look at the Wicked Witch's nose, you can see that in some scenes the prosthetic nose is barely longer than Margaret Hamilton's real nose. In other scenes, the tip of her fake nose hooks almost all the way down to her mouth.

Continuity: The characters change places from one shot to another as the Wizard gives the Tin Man his heart, etc.

Other: The shadow of a bird stretching its wings can be seen on the painted sound stage wall slightly to the right of the house as they exit the Tin man's scene singing, "Were off to see the Wizard".

Continuity: 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.

Continuity: Dorothy says, "Oh, now I'll never get home" and her dress is clean. Several shots later the Tin Man asks, "What have you learned, Dorothy?" and there are now spots all over the front of it that last for the rest of the scene.

Audio problem: Just before Dorothy lets the scarecrow down, his lips don't match what he is saying.

Continuity: 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.

Revealing: When everyone is still in the poppy field, after the snowstorm, Dorothy says "Look. Emerald City is closer and prettier than ever." Look behind the Lion just as Dorothy says the word "City" and you'll see that the wire attached to his tail brushes over the top of some of the poppies, knocking the snow off.
