Part one of the highly anticipated London stage production Harry Potter and the Cursed Child began previews on Tuesday night – and from the sound of it, the show is even more magical than one could have hoped.

A select few fans from around the world gathered at the London Place Theatre to finally learn what is happening in the wizarding world 19 years after the events of Harry Potter and the Deathly Hallows.

Before the show, fans took to social media to share their excitement and anticipation for what was about to come.

It’s here it’s here!!

Reading the cast/character list in the program (unannounced til now) gives you good sense of where the story is gonna go #KeepTheSecrets

Before the show began, Harry Potter author J.K. Rowling appeared in a video asking fans to keep the content of the play a secret. Afterward, she reminded fans to be extra-careful about spoiling the play by using the hashtag #keepthesecrets.

Potter fans have always had each other’s backs. Today I’m asking you to #KeepTheSecrets of #CursedChildhttps://t.co/0Vbl3zwN6b

And fans have been keeping that promise, limiting their social media posts to just their feelings about the play.
