I read that the book on which the film is based on is 600 pgs, anyone heard of this book before this film. Just curious to see how closely the film followed the book.

The director has an interesting story, he's 47 years old (who woulda thought this by watching this film) and used to do commercials (thus, he says explains his skill for being straightforward and fast-paced) in Brazil (considered the best in advertising).

And, he turned down serveral Hollywood offers, they offered him huge budgets and all, but he turned em down.
