Hi. I saw a movie when I was young. It was probably around the early 70's or so. I thought the title was "Sand Castles", but I cannot find info on line.

All I can remember is that it involved a young couple (young teens) and that the boy died and came back as a ghost. He built sand castles on the beach for his girlfriend. He and the girl always met on the beach in the evening. I'm not sure, but I don't think she knew he was a ghost.

I would like my daughter to watch this movie.

Yeah, I remember it... Jan Michael Vincent was in it. I think that it was a TV movie. Maybe that's why you're having trouble finding it. Sandcastles is one word, maybe try searching that way.
