This is a very good documentary on the greatest spy of them all, 007, James Bond. I'm not a huge Bond film fan, but this doc is really well done, talking to almost all of the actors who have played the character. There really aren't that many of them.
Of course, it's completely wrong about being the longest running film film franchise in history. Godzilla alone has more movies and started years before Bond graced the screen. Sorry Bond, but you lose this one.
