Twenty years after the release of Harry Potter and the Sorcerer’s Stone there is going to be a magical anniversary.

Cast members from all eight Harry Potter films will appear and recount the making of Harry Potter and the Sorcerer’s Stone, 20 years after its theatrical release.

Harry Potter 20th Anniversary: Return to Hogwarts will premiere Jan. 1 on HBO Max, right as the clock strikes midnight and the new year begins.

It’ll also also air on TBS and Cartoon Network in spring 2022, just before the theatrical release of Fantastic Beasts: The Secrets of Dumbledore.

In addition to interviews and cast conversations, the 20th anniversary special will give an in-depth look into how the first Harry Potter movie was made.
