Continuity mistake: In the shot from behind them, the three look down at the entrance to the Wicked Witch's castle and the Scarecrow picks Toto up in his arms. In the next shot Toto is on a rock barking. (01:21:40)
Continuity mistake: When Scarecrow, Tin Man, and the Cowardly Lion are marching into the Wicked Witch's castle after taking the guards' uniforms, all three of them are shown holding the same types of spears as the guards, so when they go rescue Dorothy out of the locked room and Tin Man chops through the door with his axe, where did the axe come from? (01:22:50)
Suggested correction: I'm 63 years old and still watch The Wizard of Oz. If I remember correctly, the axe was taken off a nearby wall.
There is no scene of him taking the axe off the wall, nor is there any axe seen on any of the walls. Plus, it's the same axe he had the whole time. But the 3 also take off their coats/disguises while the camera is on Dorothy and it's possible he had the axe tucked away in the coat.
In the books, the Tin Man always has his axe and he uses it often. Perhaps it is the same in the movie.
Continuity mistake: At the Witch's door the Tin Man is not the wearing his metal suit underneath the guards clothing. Look at his waist. (01:23:30)
Continuity mistake: When the Tin Man starts chopping the Witch's door his axe has marks all over it. Several shots later he raises it again to chop down another door and it's as new as the day he bought it. (01:23:35)
Continuity mistake: The Tin Man starts chopping the Witch's door and it's not the same one we just saw three shots before. The wood is a different color and the dark metal brace has been polished in the close-up. (01:23:40)
Continuity mistake: At first the Tin Man starts chopping the top part of the Witch's door with his ax and two shots later he's chopping about two feet lower, near the handle. If you look closely when he eventually gets the door open, the top part has not been touched. (01:23:40)
Continuity mistake: As the Tin Man chops open the Witch's door only one piece of wood has fallen off of it. In the next shot when Dorothy comes through there's much more rubble on the floor (in front of and behind the door) than there should be. (01:24:00)
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: As the Wicked Witch puts her flaming broomstick on the Scarecrow, look closely at the Tin Man. His chest dent that we saw several shots earlier on the left side of his costume, has been dented out. (01:24:20 - 01:26:15)
Continuity mistake: The Tin Man looks at the rope that holds up the chandelier and it's covering the knot. The next time we see it as he takes the axe to it, the rope is on the left of the knot. (01:24:40)
Continuity mistake: When the Wicked Witch throws the hour glass down at them the monkey on her right runs and hides behind the statue. In the next shot he's back sitting right next to her. (01:24:45)
Continuity mistake: As the Wicked Witch throws her hour glass at them we see behind her as she stands on the balcony, and her broomstick is definitely not anywhere near her. As she runs down the stairs, it's in her hand. (01:24:45)
Continuity mistake: As the chandelier falls on the guards at the witch's castle, all the candles are blown out by the time it lands. The next shot shows some of them relit. (01:24:50)
Continuity mistake: When the Tin Man, Scarecrow, Cowardly Lion and Dorothy are cornered in the witch's castle, the scarecrow grabs the Tin Man's axe and chops a rope, releasing the chandelier, which falls on the guards. In the next shot, however, as the witch is shrieking "seize them", the guards give chase with only 1 or 2 laying on the floor. (01:24:55)
Continuity mistake: The Scarecrow is in the lead as the four run away from the guards and enter the tower where the Wicked Witch is eventually melted. In the next shot the Tin Man is in front. (01:25:35)
Continuity mistake: As the four enter the tower where the Wicked Witch is eventually melted, we see guards and steps on the left of the tower. When seen from above the entrance that the guards use is on the right of the tower. (01:25:35)
Continuity mistake: The Wicked Witch enters the tower and says, "Ring around the Rosie" and the broom in her hands changes between shots. The one she sticks in the fire is different. (01:26:00)
Continuity mistake: When the Witch melts, the broom is laying several inches from her dress. In the next shot, the broom is practically touching her dress. (01:26:20)
Continuity mistake: Immediately after Dorothy throws the water onto the witch, there is a long shot of the group as they observe the Wicked Witch beginning to melt. In this shot you can see that the Scarecrow's arm is still on fire, yet nothing is done about it as they all focus on the Witch. In the next full shot of the Scarecrow the fire is completely out. (01:26:20)
Continuity mistake: 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. (01:26:20)
