I read the book long before I saw the movie. And it probably says something about the book that what I remember most vividly is the scene where after Brody's wife has had nooner sex and is contemplating, now that she has two examples to generalize from rather than just one, about the differences between the way men and women pee.

To be fair, it wasn't the sex and peeing that interested me; it the the point of view and internal dialogue. Back then, I wasn't an editor, but I guess I was born to be a structure geek.
