This movie starts with a girl riding in the back on a car, the car crashes and she flies out and hits her head. Then the movie turns into a fantasy where there is a girl being forced to marry a guy she doesn't want to marry. There are some funny character guys that are trying to help her escape. At one point they're running through what I think was a factory or bakery. Then they fall through a trap door and down a tunel that ends up in a dungeon like place where a witch lives. I think the witch lives in a bowling ball like structure up on a hill and watches people in the town. At the end of the movie the ball rolls down the hill and into the town... Anyone know what it's called? It's really bothering me I can't think of the title.

It doesn't sound exactly like it, but could it be Labrynth

I was looking for the same movie, and found it! It's called Babes in Toyland with Keanu Reeves and Drew Barrymore.
