Who is returning for the HBO Harry Potter series?
According to reports citing the Press Association, Davis — who also portrayed goblin Griphook in the film franchise — is coming back as Hogwarts charms professor Filius Flitwick. Collider notes he is the notable piece of continuity amid an otherwise largely new ensemble for the reboot.
The Islington Gazette reports Davis, 56, is so far the only original-film cast member to reprise a role for the “top secret” TV series. He played Flitwick across a decade of blockbusters, including memorable charms lessons in Harry Potter and the Philosopher’s Stone.
What did Warwick Davis say about reprising Flitwick?
Speaking to the Press Association, Davis said Flitwick “has been one of my favourite characters to play in my career,” describing him as warm and likeable. He explained that he based the professor on some of his own teachers — the kind who would forgive forgotten homework with a gentle warning.
“To be asked to come back and play him again for the series was a huge honour, and I’m excited to retell these stories because they’re fantastic stories,” he said, while adding he cannot share production details because the project is “all very top secret.”
Davis also called Harry Potter a “constant” in his professional life after more than 11 years on the films and ongoing work with the studio tour in Watford. Linking that run to his long involvement with Star Wars, he called both franchises a “terrific honour” and described the Potter connection as “fabulous.”
