Subtitled : Inconceivable Tales From the Making of The Princess Bride
Nonfiction by Cary Elwes.
I really enjoyed this book, because I love The Princess Bride. It really went into the minutiae of the movie, so if you aren't a fan of the film, you wouldn't care for it.
But if you've seen The Princess Bride enough times to have it almost memorized (like me) then you'll love it. Inside info! Woo-hoo! For example: Cary Elwes' ponytail and mustache: real or fake? I must know.
And the audiobook makes it even better, because it uses the actual actors' voices.
BTW: the mustache was real; the ponytail was fake. Mystery solved.
