I think Verhoeven had already another script ready and he mixed it with some stuff from the books. He also produced a 3d cartoon named Roughnecks Starship Troopers Chronicles which adds more stuff from the books.
Pretty sure I watched most of that cartoon series, if Verhoeven added more stuff from the books, it wasn't obvious... unless we're talking about aesthetics and not ideas.
