Lost childhood movie 70's maybe 80's
I'm trying to find the title of a movie I distinctly remember watching as a kid. The plot goes somewhat like this:
A boy travels back in time to ancient Egypt where he meets an Egyptian family with a little girl his age. She turns out to be some sort of important character, future queen or something. He then find out that the family is arranging a future marriage or something like that to the girl and tries to get back home. When he arrives home, a new family is moving into his block, and his new neighbor looks exactly like the girl he met in ancient Egypt.
Any ideas as to what this movie or TV special was?
