True to the book?
I just read this book a while back, and I've always wondered whether the movie was faithful to it. I've seen the Matt Damon Bourne films which are nothing like the books, but thats because of the length of the books and the different time-frame (which made elements like Carlos, Bournes Vietnam War background etc) impossible to adapt.
But considering that The Ostermand Weekend is a pretty small book and easily adaptable as such and as the time frame of the movie was more or less the same as the book (Cold War era), was it faithful?
