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.

Harry Potter

Movies: Daniel Radcliffe / Show: Dominic McLaughlin

Hermione Granger

Movies: Emma Watson / Show: Arabella Stanton

Ron Weasley

Movies: Rubert Grint / Show: Alastair Stout

Headmaster Albus Dumbledore

(Or, if we’re being formal about things: Albus Percival Wulfric Brian Dumbledore).

The movies: Richard Harris and Michael-Gambon / Show: John Lithgow

Professor Minerva McGonagall

Movies: Maggie Smith / Show: Janet McTeer

Professor Severus Snape

Movies: Alan Rickman / Show: Paapa Essiedu

Gamekeeper Rubeus Hagrid

Movies: Robbie Coltrane / Show: Nick Frost

Molly Weasley

Movies: Julie Walters / Show: Katherine Parkinson

Draco Malfoy

Movies: Tom Felton / Show: Lox Pratt

Lucius Malfoy

Movies: Jason Isaacs / Show: Johnny Flynn

Lucius doesn’t appear in the first Harry Potter film (or book), but he’s one of a few characters that are among the first season’s cast that don’t show up until later in the film series (others include Parvati Patil and Cornelius Fudge).

Neville Longbottom

Movies: Matthew Lewis / Show: Rory Wilmot

Dudley Dursley

Movies: Harry Melling / Show: Amos Kitson

Fred and George Weasley

Movies: James and Oliver Phelps / Show: Tristan and Gabriel Harland

Ginny Weasley

Movies: Bonnie Wright / Show: Gracie Cochrane for season one and Bonnie Hill for season two — the first recasting of the series.

Percy Weasley

Movies: Chris Rankin / Show: Ruari Spooner

Madam Rolanda Hooch

Movies: Zoe Wanamaker / Show: Louise Brealey

Garrick Ollivander

Movies: John Hurt / Show: Anton Lesser

Seamus Finnigan

Movies: Devon Murray / Show: Leo Earley

Parvati Patil

Movies: Shefali Chowdhury and Alessia Leoni

Vernon and Petunia Dursley

Movies: Richard Griffiths, Fiona Shaw / Show: Daniel Rigby, Bel Powley

Minister Cornelius Fudge

Movies: Robert Hardy / Show: Bertie Carvel

Arthur Weasley

Movies: Mark Williams / Show: Rafe Spall

Professor Quirinus Quirrell

Movies: Ian Hart / Show: Luke Thallon

Caretaker Argus Filch

Movies: David Bradley / Show: Paul Whitehouse

Lily Potter

Movies: Geraldine Somerville / Show: Hannah Chinn

James Potter

Movies: Adrian Rawlins / Show: Jasper Talbot (both Lily and James are closer to the ages in the books — 21 — than the actors in the films)

Professor Filius Flitwick

Movie: Warwick Davis / Show: Also Warwick Davis! The only original cast member to return and reprise their movie role.

Tom Riddle

Movies: Christian Coulson, Show: Billy Barratt (for season two of the Harry Potter series based on Harry Potter and the Chamber of Secrets)

Moaning Myrtle

Movies: Shirley Henderson / Show: Molly Hewitt (for season two)

Colin Creevey

Movies: Hugh Mitchell / Show: Jasper Ambrose

Professor Gilderoy Lockhart

Movies: Kenneth Branagh / Show: Kit Harington (season two)

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.
