Calling all muggles! HBO Max has revealed a new official trailer for its highly anticipated, magic-filled New Year's special, “Harry Potter: 20th Anniversary Return to Hogwarts.”

The reunion, which was filmed in London, will include Daniel Radcliffe (Harry Potter), Rupert Grint (Ronald Weasley) and Emma Watson (Hermione Granger) and more stars from the film as they commemorate the two-decade anniversary of the Harry Potter franchise and its beloved Wizarding World, revisiting places like Diagon Alley, the Hogwarts Express station and the Great Hall at Hogwarts.

The trailer features the main trio in the Gryffindor common room, reminiscing on the decade they spent together as they produced the collection of films.

“It feels like no time has passed — and loads of time has passed," Watson, 31, remarked.

“I think this is the perfect time to sit down with everyone and reminisce,” Grint, 33, added.

Radcliffe, 32, also joined in, “The thing that scared me the most was the implication that the most meaningful thing in our life was done. And there is something so joyous about seeing everyone and (to) be, like, it wasn't though.”

The actors are also joined by fellow cast members Helena Bonham Carter, Ralph Fiennes, Jason Isaacs, Gary Oldman and more as well as filmmakers Chris Columbus, Alfonso Cuarón, Mike Newell and David Yates.

Bonham Carter, who played the malicious Bellatrix Lestrange, shared some of her favorite moments from filming the franchise.

“One of the highlights of my part was when I had to pretend to be Hermione pretending to be Bellatrix,” Bonham Carter shared, referencing a scene from the last film in the franchise, “Harry Potter and the Deathly Hallows: Part 2.” She then laughed as she shared the memento she took with her from the set. “I’ve still got the teeth, actually, I’ll put them in if you want."

Fiennes, who played the role of Voldemort, the dark lord who infamously "shall not be named," chimed in, sharing how he once questioned taking the villainous part.

“My sister has children, who at the time were around 10, 11, 12, and I said, ‘Martha, I don’t know about this Voldemort,’” to which his sister responded, “'What! You have been asked to play Voldemort? You’ve got to do it!'”

The trailer ends as Radcliffe, Grint and Watson laugh and lock hands, sharing a sentimental moment.

“I wouldn’t be the person I am without so many people here,” Radcliffe said.

Watson added, “There is something about 'Harry Potter' that makes life richer.”

“We’re family and we’ll always be part of each others’ lives," Grint concluded.

The streaming service also revealed official art for the special, which reads, “Welcome back to where the magic began.”

"Harry Potter: 20th Anniversary Return to Hogwarts" will be available to stream on HBO Max starting Jan. 1, 2022, and will stream on TBS and Cartoon Network in spring of 2022.
