Watch the sentimental first trailer for Harry Potter 20th Anniversary: Return To Hogwarts

The brand-new trailer for the Harry Potter 20th anniversary special has hit the internet – and it is emotional.

Daniel Radcliffe, Rupert Grint, Emma Watson and more reunite on-screen to mark the the 20th anniversary of the first film, The Philosopher’s Stone (also known as Harry Potter And The Sorcerer's Stone), sharing their memories and feelings towards a franchise that changed their lives.

As well as our beloved core trio of Harry, Ron and Hermione, other cast and crew alike are brought together to celebrate all things Harry Potter, including *deep breath* Helena Bonham Carter, Robbie Coltrane, Ralph Fiennes, Jason Isaacs, Gary Oldman, Tom Felton, James Phelps, Oliver Phelps, Mark Williams, Bonnie Wright, Alfred Enoch, Ian Hart, Toby Jones, Matthew Lewis, Evanna Lynch, producer David Heyman and filmmakers Chris Columbus, Alfonso Cuarón, Mike Newell and David Yates.

And the sentimental trailer for Harry Potter 20th Anniversary: Return To Hogwarts already has plenty of memorable moments, from Helena Bonham Carter casually bringing out the fake teeth she wore in the movies as Bellatrix Lestrange, to Ralph Fiennes remembering his family's reaction when he first told them he was going to play He-Who-Must-Not-Be-Named…

Watch the trailer below:

Harry Potter 20th Anniversary: Return To Hogwarts will air on January 1, 2022. It'll hit Sky and streaming service NOW.
