Flubs Jokes

I'm amazed more people haven't spotted these film flubs:

* Part of the movie is in black and white, then inadvertently goes to color, and then back to black and white! An obvious continuity gaffe.

* Although the movie purports to be in Kansas, several scenes are obviously filmed on a Hollywood sound stage.

* The scene where the teacher rides past Dorothy's bedroom window in the midst of a tornado is physically impossible.

* When the characters sing you can hear music accompanying them but there are no radios or musicians in the area!

* For a land to exist "over the rainbow" it would have to be lighter than air, and as Dorothy was already shown to be composed of solid matter, how come she didn't fall back down to earth?

* Some of the so-called "munchkins" are obviously children wearing fake facial hair and grown up clothes.

* The "yellow brick road" is not really yellow as much as more...
