unfilmable so they did Hunt for Red October instead.
I read the book and was kinda amazed how they made that turd of a book into actually good movie. They had to cut off like 3/4th of anticommunism and russophobia from it lmao. On a side note, if the Annapolis cadets really used that book as a textbook in the 80's, i'm not even surprised how that generation which is now runing US Navy is crashing it to the ground hard.
Also fun GIUK fact: it played certain hilarious role in Cod Wars
