20 Things You Didn't Know About Gone Girl
7. The Blu-Ray Comes With An Actual Amazing Amy Book
A crucial plot point in the movie is the fact that Amy is a beloved public figure due to being the inspiration for her parents' popular children's book series Amazing Amy.
Brilliantly, Gone Girl's Blu-ray release takes this one step further by including some physical supplementary material - a 36-page Amazing Amy book called "Tattletale."
The book is written in the cheery style of a kids' book as you'd expect, without getting especially self-aware or winking at fans of the movie. According to audience reviews, it's actually pretty good. Not bad for a freebie, then.
