The ironic part of Moonraker, the hard copy from Jonathan Cape of the novalization of the 1979 movie goes for about $2,000.

When a book is sold to the movie makers they call in pro script writers to work it over, often leaving nothing from the book but the title and main character.

Years ago I read a book THE GUN by C S Forester. It was later made into a movie THE PRIDE AND THE PASSION and was greatly changed form the book, almost like a completely different story, but still worth watching.
