Watch: HBO Max Celebrates Harry Potter 20th Anniversary ‘Return to Hogwarts’

Warner Bros and HBO Max are planning to ring in the New Year with a return to the Wizarding World. Harry Potter 20th Anniversary: Return to Hogwarts is a retrospective special marking the 20th anniversary of Harry Potter and the Sorceror’s Stone‘s release and will feature many familiar faces.

Now we have our first look at the retrospective courtesy of a new trailer, which gives us some peeks at the franchise stars as they receive a letter inviting them to remember their time working in Harry Potter.

Daniel Radcliffe, Emma Watson, and Rupert Grint will all be making an appearance, but the new trailer also confirms that we’ll see Helena Bonham Carter, Robbie Coltrane, Ralph Fiennes, Jason Isaacs, Gary Oldman, Tom Felton, James Phelps, Oliver Phelps, Mark Williams, Bonnie Wright, Alfred Enoch, Matthew Lewis, and Evanna Lynch contributing to the nostalgia. You may notice that the series’ creator, J.K. Rowling, is conspicuously absent from the event.
