The new teaser opens with a quick shot of the Hogwarts clock tower and the Daily Prophet that reads “Hogwarts welcomes back alumni.”

Then, we get glimpses of the cast opening invitations for the big reunion. Robbie Coltrane, who portrays Hagrid, is sitting in a coffee shop when he receives his letter. Matthew Lewis, known for his role as Neville Longbottom, is next to acquire his invitation. Then, Mark Williams, who plays Mr. Weasley, is standing aboard the Hogwarts Express.

Going in for extra nostalgia, we see Platform 9 ¾ briefly shown. In what appears to be Emma Watson, a female sporting a hat is seen walking familiarly among the bustling scene. The trailer closes with a shot of the Hogwarts Express pulling into the platform.

Harry Potter 20th Anniversary: Return To Hogwarts is set to air on HBO Max New Year’s Day.
