We're going back to Hogwarts.

Exciting news for Harry Potter fans this morning, as a reunion marking 20 years since the first film is set to take place on New Year's Day. Daniel Radcliffe, Rupert Grint and Emma Watson - who played Harry Potter, Ron Weasley and Hermione Granger - will come together for Return to Hogwarts, a TV special which will air on HBO Max. The trailer for the reunion dropped yesterday, and it opens with the dulcet tones of Albus Dumbledore (Michael Gambon) telling us that time is a "mysterious thing", and that when we're in doubt, we should "retrace" our steps. https://twitter.com/TomFelton/status/1460693177770426377?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1460693177770426377%7Ctwgr%5E%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fnews.sky.com%2Fstory%2Fharry-potter-reunion-daniel-radcliffe-emma-watson-and-rupert-grint-to-star-in-tv-special-20-years-on-from-first-film-12470488 They will be joined by director Chris Columbus to share insights into the filming of the franchise.

Emma Watson shared her delight at the upcoming reunion with her Instagram followers last night. She posted throwback photos with the cast and 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 the path. https://www.instagram.com/p/CWWGFOXLZYs/ "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." She added: "Thank you to the fans that have continued to show their support well after the last chapter closed. The magic of the world wouldn't exist without you. Thank you for fighting to make it such an inclusive and loving place." Tom Felton, meanwhile, took to Twitter and wrote: "is this what school homecoming is like? mark your calendars for New Years Day #ReturnToHogwarts, streaming on @hbomax x".
