To many, a school reunion is not an ideal prospect. That, of course, excludes a Hogwarts reunion. Celebrating the 20th anniversary of Harry Potter and the Philosopher’s Stone, HBO Max are set to take us back to the iconic school with Daniel Radcliffe, Emma Watson and Rupert Grint. Sitting down with American filmmaker Chris Columbus to discuss the making of the first film, the trio are set to look back on their time in the franchise and how it changed their lives forever.

Joined by the likes of Helena Bonham Carter, Robbie Coltrane, Ralph Fiennes, Jason Isaacs, Gary Oldman, Imelda Staunton and Tom Felton, the special comes 20 years on from the US release of the first film, on 16 November 2001.

In a recent Instagram post, Emma Watson, who plays Hermione Granger, wrote: “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. I am proud we were kind to each other, that we supported one another and that we held up something meaningful.”
