Harry Potter film stars, including Helena Bonham Carter (Bellatrix Lestrange), Tom Felton (Draco Malfoy), Matthew Lewis (Neville Longbottom) and others attended an exclusive preview of The Wizarding World of Harry Potter – Diagon Alley at Universal Orlando Resort on Wednesday.  Arriving on a red carpet that stretched from King’s Cross Station to the picturesque “London,” the cast celebrated the announcement of The Wizarding World of Harry Potter’s grand opening date – recently revealed to be July 8. Robbie Coltrane led event attendees inside the land by ceremoniously tapping the bricks of Diagon Alley – just like Rubeus Hagrid did in the Harry Potter books and films.
