It’s been only 15 years since Warner Bros. released Harry Potter and the Deathly Hallows, yet a fresh adaptation of J.K. Rowling’s massively popular novels is coming this Christmas.

For HBO’s new TV series version of the Harry Potter saga, each book following the boy wizard’s Hogwarts journey being adapted into a full season. The major roles from Rowling’s first two novels — Harry Potter and the Sorcerer’s Stone and Harry Potter and the Chamber of Secrets — has been recast with different actors than those who played the characters in the Warner Bros. films. The adult actors are often much younger than their film counterparts, as the show is sticking closer to the characters’ ages in the books.

Below are all the actors who have been announced, with photos showing them side by side with their film version counterparts.

  • Lord Voldemort

    Movies: Ralph Fiennes / Show …

    Nobody has yet been announced for the franchise’s biggest villain, but an interesting question is: When will the main actor for the role first show up? In the films, Fiennes didn’t appear until the forth movie, Goblet of Fire, as that’s when Voldemort first takes human form. But his face appears at the end of the first film (played by Richard Bremmer), and in the second film, he appears as his younger self, Tom Riddle (played by Christian Peter Coulson). Given the production has cast several roles that didn’t appear until the latter films, it wouldn’t be at all surprising if the production has quietly already cast an actor to play Voldemort throughout the entire series.
