I saw it when I was little, so it was late 70's or early 80's.
All I remember was a little girl ( like 5 or 6 years old )
standing on the beach, it was the end of the movie, the "leave
you hanging--wonder if there's going to be a sequal" part.... the little girl was just standing there,
and she had a mark on her belly. It was in the shape of a bowtie and
it was red.I'm pretty sure the movie had something to do with spiders. black widows, maybe?
