Live and Let Die was an AWESOME book. Unquestionably my least favorite movie, but perhaps my favorite book. So much of the cool stuff that was in Licence to Kill was actually taken from that book, including what happened to Felix Leiter. Plus the bad guys had some one-liners about him that usually we only hear from Bond in the films.
And I already gushed about Moonraker. If they'd only adapt THAT plot into film ...
