The first teaser for the TV special ‘Harry Potter 20th Anniversary: Return to Hogwarts’ is out and gives a peek into what fans can expect from it when it releases on January 1 on HBO Max.

One thing’s for sure — all the biggest stars from the iconic movie franchise are making a comeback.

The teaser stars with what seems to be actress Helena Bonham Carter reading a copy of the fictional and magical Daily Prophet newspaper, with a headline that reads “Hogwarts welcomes back alumni”.

Then stars such as Robbie Coltrane (who played Rubeus Hagrid), Matthew Lewis (who played Neville Longbottom) and Mark Williams (who played Arthur Weasley) get their wax-sealed invitations and board the train at Platform 9 3/4.

The TV special will celebrate 20 years since the release of the first movie in the series, ‘Harry Potter and the Sorcerer’s Stone’, based on JK Rowling’s books. According to Deadline, the show will feature interviews and cast conversations.
