Did you know the Rambo franchise started with a novel about a man bringing the war back home with him? Let’s watch What’s the Difference and Lost in Adaptation.
David Morell’s career was really kicked off with Stallone wanting to make his first book into a movie. It wasn’t just that the franchise allowed him to become a full-time author, it was that he’d been rather savvy in retaining a few of the rights to the character and spinoffs.
Essentially, despite the fact that very little of his character remains in the sequels, Morell wrote the novelisations of the films, keeping his piece of the franchise $$. He has said that those sorts of IP negotiations can make a huge difference to a writer’s career.
Having read several of Morell’s books, I think most thriller fans would enjoy his work. And if you like the entire third act of a film being a buff guy shooting a large calibre machine gun at people, you’ll probably enjoy the Rambo films.
