Do you have a link to that? I can't find anything that ties Smith to this story.
It’s based on one of his books. I can’t remember which one, but I saw the movie when it came out. I was disappointed in the movie because I didn’t think it did the book justice.
I have often wondered why more of his books haven’t been made into movies. G & D is the only one, as far as I know, and it was not acclaimed.
