Last Saturday, Eddie Redmayne and the cast of Fantastic Beasts and Where to Find Them bewitched the fans of Comic-Con. Not only did they bring an all-new trailer that set the internet abuzz, but they made sure Hall H stood for "Hogwarts" with a giveaway of 6,500 magic wands before signing autographs for thousands of fans. 

Turns out, that was just the beginning of a week's worth of Pottermania, as Harry Potter and the Cursed Child -- the all-new play with a sold-out West End run and earning rave reviews here at home -- will be released as a book this Saturday, July 30 at midnight. 

Given the buzz, it's fair to wonder how exactly the play (written by Jack Thorne and based on an original story by J.K. Rowling, Jack Thorne and John Tiffany) has managed to keep its surprises and twists hidden to date. Turns out, Rowling herself managed the feat with a little magic herself: Through an old-fashioned request of Muggles the world over. 

Check out the video below, and pick up a copy of Harry Potter and the Cursed Child when it's released this weekend. Just remember to #KeeptheSecrets.
