Audio problem: When Dorothy and the Scarecrow find the apple trees she says, "Oh, look, oh". The overdub is wrong, if you look closely at her mouth when she turns around toward the camera she's actually not saying anything.

Continuity: As Dorothy throws the water on the Wicked Witch the Tin Man goes from holding his ax in front of him to holding it close to his chest with the ax head sideways between shots.

Continuity: As the Wicked Witch walks over to her sister a rocking chair is protruding through the broken window. In the next shot the window frame disappears and it's not a rocking chair anymore that's protruding from the window.

Visible crew/equipment: When the Wizard says, "Do you presume to criticize the great Oz?" look closely at the curtain as a crew member behind the curtain attaches it onto Toto so he can pull it open.

Visible crew/equipment: As the talking trees throw their apple's at Dorothy and the Scarecrow, look closely at the upper right hand side of the screen. An off camera crew member is shaking one of the trees back and forth as all of the others stand motionless.

Continuity: 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 than picks up the bucket behind it on the bench and proceeds to feed the pigs. He empties the first bucket than picks up the second empty bucket, which is now three quarters full.

Continuity: Just before the Wicked Witch leaves Munchkinland she says to Dorothy, "just try to stay out of my way" and her broomstick is facing upwards. In the next shot it's facing downwards.

Visible crew/equipment: When Dorothy lands in Oz and exits the house to Munchkinland, the camera pans around the land. When it slowly pans over a large bed of tall flowers, you can clearly see a very large shadow passing over them. Obviously the shadow of camera equipment or a camera crane.
