If you could turn one unfilmed novel into a movie which would it be?(r/AskReddit)
Old Man’s War. It’s about an old man who joins the armed wing of Earth’s colonizing force, which only recruits from the oldest portions of society. It’s the first book in a series of books that deal with mankind’s expansion into space, and the possible problems.
If you like science fiction, go buy it right now. Don’t look at any plot descriptions, because most of them spoil the questions surrounding why only the old are recruited, which doesn’t get answered until a third of the way into the book.
