I watched this movie years ago, so it had to have been made before the 1990s. It's about a girl searching for her kidnapped baby brother. In one scene she is running along a ravine that never ends, and a colorful worm tells her how to walk through the wall. There's also a part where she falls down a hole and blue, talking hands catch her. The bad guy is a white man with white crazy hair.

That's all I remember of the movie. If you have any knowledge of this movie please help me! It's driving me crazy!

Sounds like,.

Labyrinth

A teenage girl has to baby-sit her cranky baby brother for an evening. He's crying and she's at her wits end. She started to tell a story about a little boy taken away by goblins. She wishes that the goblin king would take her brother away. A moment later,the lights went out, and when she looked in the crib her baby brother was gone.
The goblin king appears in the nursery and tells the young woman that if she wants her brother back she'll have to go to his goblin kingdom and make it through the dangerous maze surrounding his castle. If she fails to do it in time her baby brother will become a goblin.
