Don't freak out, but something magical has just appeared. A behind-the-scenes featurette for Fantastic Beasts and Where to Find Them has arrived as part of the "Celebration of Harry Potter" event. Even if you already know all there is to know about Fantastic Beasts, this is really exciting. We get to go back to the wizarding world, and there are all-new characters to get to know! It's simply the best.
