Earlier this morning we were at a press conference for the Diagon Alley Media Preview and during the event Matthew Lewis along with James Phelps, Oliver Phelps, Evanna Lynch and Thierry Coup (Senior Vice President, Universal Creative) announced that Diagon Alley will be open on July 8th.
We will have a full video of the announcement later tonight or tomorrow!
Universal also released a new commercial which can be seen here.
