There is a childhood movie I used to love! It was a woman who would change heads! She would just pick one for the day like they were shoes. But this was not a scary movie! It's a kids movie! I believe it was made in the 70;s or 80's! Can anyone help!

There was a oz sort of sequel with a bad guy/lady who would change heads. And she wanted dorathy's. Called return to oz

Iuno if it's the one your talking about, cause it scared me, lol but it has a lad who changes heads.

"Storybook" had a witch who changed wigs. Maybe you're thinking of that. If not I'd agree with Avemtilla.
