I’m listening to the audiobook of “As You Wish: Inconceivable Tales From the Making of the Princess Bride” by Cary Elwes and it is INCREDIBLE. Highly recommend reading (& in particular listening) for any fans of the movie.
It’s got a ton of fantastic behind-the-scenes stories like how Mandy Patinkin bruised a rib from laughing at Billy Crystal’s ad-libbing, & many of the actors themselves narrate their own memories - it’s fun to hear their voices.
