Clancy has enough money to produce the movies himself; he doesn't need Hollywood's spin. Quit selling the film rights, Tom. You will make more money producing YOUR vision of YOUR novels.
If his movies are distorted to this extent, he has only himself to blame. I don't read his books or watch movies made from them, but do know of problems in dealing with HoWood studios. One client of mine who had absolutely NO clout whatsoever sold her story to a studio and demanded and got a clause inserted stating that the woman who played her in the film would have to be Hispanic, as she was herself. If unknown people can insist on such integrity, a mega-HoWood player like Clancy should insist on quite a lot and expect to get it.
I too have read everyone of his books...and I agree with you and everyone who is saying he needs to become more involved in the "Hollywood" versions. IMHO the only really good one was "Clear & Present Danger" and even that was butchered!
But, while his books are good, filled with interesting (if not just a little too perfect) characters, and intersting story lines; they do stretch the imagination a bit too far regarding the eventual outcomes. His work has gone down hill in his last couple of books (The Bear & the Dragon" and "Rainbow 6").
I think he's getting a bit lazy, or has cut a deal to be paid by the number of words (What was the point of inserting the "sub-story" about the militiamen in "Executive Orders?"). "The Bear & The Dragon" did not have a satisfactory ending...it just ended when Tom appeared to get bored with the writing.
Finally, my last "peeve:" Clancy couldn't write a "love scene" if his life depended on it! For goodness sake he was an Irish Catholic Insurance Agent! His love scenes seem like they were written by a... well, to put it mildly: An Irish Catholic Insurance Agent! (Don't flame...I'm Irish Catholic.)
