Harry Potter's finest faces receive their invitations to the reunion special in a brand-new teaser.
Celebrating The Philosopher's Stone turning 20, the HBO Max production flies onto screens this coming New Year's Day, with behind-the-scenes juice and never-before-seen clips poured over by the franchise's ensemble cast.
Alongside the main trio, Daniel Radcliffe (that's Harry Potter himself), Emma Watson (Hermione Granger) and Rupert Grint (Ron Weasley), we also have Helena Bonham Carter (Bellatrix Lestrange), Ralph Fiennes (Lord Voldemort), Gary Oldman (Sirius Black), Imelda Staunton (Dolores Umbridge) and Matthew Lewis (Neville Longbottom) in attendance.
Rubeus Hagrid's Robbie Coltrane, Draco Malfoy's Tom Felton, Luna Lovegood's Evanna Lynch and the Weasley troupe of Mark Williams, James/Oliver Phelps and Bonnie Wright are involved too, whilst Philosopher and Chamber of Secrets director Christopher Columbus also join the impressive line-up.
You can check out the magical first-look trailer for yourself above.
The reunion special was shot somewhere fans of the franchise may already be familiar with, the Warner Bros Studio Tour London – The Making of Harry Potter.
Just last month, Emma Watson paid tribute to the Potter world with a touching social media post.
"Harry Potter was my home, my family, my world and Hermione (still is) my favourite fictional character of all time," she wrote on Instagram. "I think a journalist once said it was irritating how many times during an interview I mentioned how lucky I was and started counting... BUT I DAMN WELL KNEW!!! And still know.
"I am proud not just of what we as a group contributed as actors to the franchise but also as the children that became young adults that walked that path. I look at my fellow cast members now and I am just so proud of who everyone has become as people," she continued.
"I am proud we were kind to each other that we supported one another and that we held up something meaningful."
Harry Potter 20th Anniversary: Return to Hogwarts will premiere on January 1, 2022 on HBO Max. In the UK, it will air on Sky and NOW.
