About 35 years a go I watch a movie on TV about a group of familys living in like the Kentucky hills (something like that) and they always shuffled when they walked and never laughed. A school teacher came to teach them and had them draw some pictures about there home before they came there. Through the pictures she found out the were from another planet. They had to shuffle because they would fly if they didn't. Something on that order anyway. Can you help me find out the name?
