Draco Malfoy (Tom Felton), Luna Lovegood (aka total babe Evanna Lynch), the Weasley twins (James and Oliver Phelps) and Professor Filius Flitwick (Warwick Davis) all walked the red carpet.
Other major celebrities, like Vanessa Hudgens, Billy Bob Thornton, Steven Spielberg, Ed O'Neill, Thandie Newton and Mindy Kaling, also turned out for the event and each earned 10 cool points for Gryffindor. Anyone that supports "Harry Potter" is a friend of ours, indeed.
Kaling Instagrammed a photo of herself walking the red carpet, calling her jewelry and Helmut Lang threads her "Muggle best."
The new "Harry Potter" park has all of the trappings fans will look forward to -- you can buy a wand at Ollivanders, hang out at Hogwarts, drink Butterbeer and chew on some Chocolate Frogs while you wander around.
As model Lydia Hearst put it, this places looks "magical beyond belief."
