What is the name of this 80's or 90's kid movie with a boy and a spaceship?
This movie has a little boy that finds a spaceship that becomes his friend. The boy goes for a ride and when he comes home he has been gone for a really long time and his little brother is older than him. He gets locked up and looked at by scientists. Finally him and the space ship brake out and go back to the past and he takes some little alien animal home with him. My sister and I can't remember the name or who played the boy. Help me.
