Continuity mistake: After the talking trees throw their apples at Dorothy she walks up a small hill and finds the Tin Man. If you look behind her there's a house across the Yellow Brick Road.

Continuity mistake: 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. (00:42:45 - 00:47:30)
Continuity mistake: When they first meet the Tin Man, the Scarecrow is holding an apple in each hand. He drops the one in his right hand but the other one disappears when he reaches for the oil can.

Other mistake: In the shot after the Wicked Witch throws fire down at them they all look up at her in the wrong direction. (00:46:25)
Answer: Another fine example of the Mandela Effect. None of the "making of" books reference this alternate ending. The original book ends with Dorothy losing the slippers on her journey back to Kansas.

I also remember this scene; however, I remember it in a television movie, and it was at the beginning, not the end, of an entirely different movie.
