Corrected entry: When Dorothy is entering her house in Kansas at the peak of the tornado, she opens the screen door and it flies off the hinges and into the air but you can also see a hanging plant right in front of her ever so slightly swinging from side to side. The storm takes a door off its hinges but can't knock a hanging plant off its hook?
Corrected entry: When they are leaving the Haunted Forest, you can see a crew member with a can creating fog.
Corrected entry: When the foursome is about to leave the poppy field, the scarecrow begins to dance before any singing begins, then stops, looks around, and starts dancing again.
Corrected entry: During the march of the witch's guards, the guard playing the cymbals crashes them together at least four times, but there is no corresponding noise. (01:20:40)
Corrected entry: Throughout the first Kansas sequence Aunt Em and Hickory make references to 'that contraption' which is the reason why, "They'll erect a statue to me one day." The explanation from this is from a cut scene where Hickory (Jack Haley) is trying to build a machine that will predict the weather.
Corrected entry: In the scene where Dorothy is at the door to see the Wizard, the doorman's moustache is pointed upwards, but shortly afterwards it is pointing downwards. I believe it was changed to reflect the mood (upwards=smile, downwards=frown/sad). If I remember correctly, when it is downward, he is crying about having an Aunt Em, also. Still a mistake, but there's an explanation.
Corrected entry: When the Lion, Scarecrow, Tin Man, Toto, and Dorothy are coming out of the woods, it appears that there are miles and miles of Yellow Brick Road before they reach the Emerald City. However, when it shows them emerging from the forest and walking through the flowers, it shows that the city's a couple of hundred meters away and there's no Yellow Brick Road.
