Films from Novels

I once met a novelist named Frederick E. West. Not well known now though at one time he was a bit famous for writing the novel "633 Squadron". It was made into a film which he thought rather good - buit he never got a cent for it. I can't recall how that was - maybe it had to do with his selling it outright for ready cash or to do with American royalties not covered in an agreement.... Doesn't matter why: he was still bitter about it years later.
So was Jack Trevor Story, novelist, who often wrote in a column in a newspaper about how he had never made a penny from the film version of his most well-known novel "The Trouble with Harry".
Today there's an obituary in The Times of John Michael Hayes, a script writer for films in the 50's and 60's then later a writer for TV series. Two of his most famous film scripts were for "The Trouble with Harry" and "Rear Window". Both were directed by Alfred Hitchcock. In the obit. there was no mention of the novel from which the script was taken; you get the idea that Hitchcock had proposed the idea and Hayes had gone about writing the script. Jack Trevor Story never forgave Hitchcock.
Strangely enough no mention was made either of the original novel from which the film "Rear Window" had been taken. It was a novel in fact written by an American writer of rather horrific fiction named Cornell Woolrich.
I have a copy of "633 Squadron" signed by the author. Worth anything I wonder?
