Inside The Magic has posted a great video summary released by Universal of the Wizarding World of Harry Potter Grand Opening events that took place on June 16 and 18. The video includes a small clip of an interview with Harry Potter creator and author J.K. Rowling, who was present for both events and seems to be in as much awe of the park as her most loyal fans.
The following video is from the actual Grand Opening event on Friday, June 18; the event was scheduled to stream live, but there were technical difficulties that prevented many online viewers from seeing the event. Dan Radcliffe welcomes the class from Wilderness Oak Elementary School, who won a contest on The TODAY Show to attend the grand opening. They were the first guests allowed into the park, and were ushered in by all of the Potter cast members on hand for the celebration.
More videos from the event can be found on ITM’s YouTube page.
