I like stuff. Stuff like books…
Lexicon of the Planet of the Apes: The Comprehensive Unauthorized Encyclopedia by Rich Handley is a… well if you can’t get it from the title: just give up now.
Obviously you’ve got to like Planet of the Apes – all of it – the from the original Pierre Boulle, the movie, TV series (live action and animated), comics, novels, promotional material and including the Tim Burton film (The book was released before Rise of the Planet of the Apes).
If you’re a trivia geek like me or a science fiction geek like me or a trivia geek and a science fiction geek like me you’ll love it. It’s one of those books that you can just pick up and open a pages at random and get lost down a rabbit hole of cross-references for hours at the time.
Full Disclosure: I got to know the author Rich Handley pretty well on rec.arts.sf.starwars.misc in the 1990s.
