Of the top of my head, I can think of 8 major stories (the life stories of each of the six men in the statue [counting pre- and post- Iwo Jima as one story in each case], the top-level view of the battle, and the authors experiences while finding this information and coming to terms with his father's life), plus a number of major side-stories, such as the War Bonds tour, the creation of the statue, and the story of the photograph on which the statue was based. As a book it worked well, but I just can't see it working as a movie.
