2027 will mark the 30th anniversary Harry Potter and the Sorcerer’s Stone’s release, the book that launched what we now know as the Wizarding World franchise. That makes it all the more appropriate that in the same year, J.K. Rowling’s fantasy saga will also be adapted for the small screen. HBO’s Harry Potter TV show is still filming its first season, and 2025 was peppered with announcements about actors joining the series. Now there’s a new casting rumor for this upcoming book-to-screen adaptation making that rounds that really has my attention.
As we continue to linger in the early days of 2026, Deadline is hearing rumblings about Tilda Swinton being eyed to play Voldemort in the Harry Potter TV show. Voldemort, a.k.a. Tom Riddle, is, of course, the main antagonist of the original Harry Potter books and movies. Following Ian Hart voicing Voldemort in The Sorcerer’s Stone movie and Christian Coulson playing a teenaged Tom Riddle in The Chamber of Secrets, Ralph Fiennes portrayed The Dark Lord in The Goblet of Fire, The Order of the Phoenix and both parts of The Deathly Hallows. Hero Fiennes Tiffin and Frank Dillane also played younger versions of Tom in The Half-Blood Prince.
