Continuity mistake: When Dorothy walks on the pig sty Zeke walks to his right, looks into, than passes the bucket on the right because it's empty. He then picks up the bucket behind it on the bench and proceeds to feed the pigs. He empties the first bucket then picks up the second empty bucket, which is now three quarters full. (00:03:55)????
Continuity mistake: When the Lion, the Scarecrow, and the Tin Man are chopping down the witch's door to free Dorothy before the hourglass runs out, they are dressed in the guards' uniforms. We see the axe hit the door, and in the next wide shot they are not in the uniforms. There is a slight view of the uniforms in a pile on the floor, as if the trio had changed out of them between axe blows. (01:24:00)
Continuity mistake: In the beginning of the movie Miss Gulch parks her bike on the fence in front of the Gale's house and it's obvious that the fence continues in the same direction past the gate. When Dorothy comes back during the storm the fence now curves around right after the gate. (00:08:15 - 00:15:25)????
Continuity mistake: As they enter the scene with the Cowardly Lion, the Scarecrow falls and then jumps over a patch of weeds growing in the middle of the Yellow Brick Road. In the next shot he does the exact same thing only about three feet behind the patch of weeds that he jumped over before. (00:48:00)????
