Harry Potter 20th anniversary: How to watch the reunion special and what to expect

Rupert Grint, Emma Watson and Daniel Radcliffe at the world premiere of Harry Potter And The Deathly Hallows: Part 2 in 2011.
Believe it or not, our favourite boy wizard is celebrating 20 years since his big screen debut. Harry Potter and the Philosopher’s Stone premiered in 2001 and its stars are reuniting for an anniversary special.
Airing on New Years Day (Saturday), Harry Potter 20th Anniversary: Return to Hogwarts will see Daniel Radcliffe (Harry Potter), Rupert Grint (Ron Weasley) and Emma Watson (Hermione Granger) reunite with filmmaker Chris Columbus and other cast members from all eight Harry Potter films.
The trio, who are now in their 30s, travel back to Hogwarts for the first time since filming Harry Potter and the Deathly Hallows – Part 2, which was released in 2011, to celebrate the anniversary of the franchise’s first film.
The special will include new in-depth interviews and cast conversations, with stars including Helena Bonham Carter, Robbie Coltrane, Ralph Fiennes, Jason Isaacs, Gary Oldman, Imelda Staunton, Tom Felton, James Phelps, Oliver Phelps, Mark Williams, Bonnie Wright, Alfred Enoch, Matthew Lewis, Evanna Lynch, and Ian Hart.
Yes, but another special will be on our TV screens this week too. Tomorrow, Harry Potter: Hogwarts Tournament of Houses will air. It is a special four-part event hosted by Helen Mirren that will showcase ultimate fan glory.
Featuring hundreds of trivia questions and special guest surprises, Wizarding World fans will put their Harry Potter knowledge to the test and the winner will be named House Cup champion.
