Grab your broom, get some Floo Powder or create a portkey! You’re going to want to go to London for “Harry Potter and the Cursed Child.”

“Harry Potter” author J.K. Rowling was on hand at the Palace Theatre in London’s West End for the official premiere of her new play, the eighth installment in the franchise. The 50 year old had a smile on her face at the opening gala event as she greeted fans and thanked them for keeping spoilers under tight lock and key.

“Harry Potter and the Cursed Child” has been in previews for the past few weeks with reviews being released earlier this week. The play, which is actually presented in two parts, officially opened Saturday. Rowling walked the red carpet with her co-writer, Jack Thorne, as well as producers Sonia Friedman and Colin Callender.

As mentioned above, “Harry Potter and the Cursed Child” has been in preview, which means that some lucky muggles have already had the opportunity to watch the play. Rowling previously urged viewers not to share spoilers, and thanked her devoted fan base at the event for keeping their word.

“They’ve been amazing, they’ve been incredible, and you know what it is? It is the most extraordinary fandom so I’m kind of not surprised they didn’t want to spoil it for each other,” she said, according to the Daily Mail. “But I’m so happy we got here without ruining it.”

Currently, the play is only on London’s West End. However, there is hope for those outside of London to get to witness the magic in person. Rowling revealed to reporters that she would “love it to go wider” than just Broadway.

“I’d like as many Potter fans to see it as possible,” she explained.

Although it may take a little while to hit the Great White Way, fans around the world will at least be able to read the play. The “Harry Potter and the Cursed Child” script is being released at midnight on July 31.
