Warwick Davis is the only actor from the films who returns in the same part: he played Professor Flitwick in all eight films, as well as the goblin Griphook. In the series he plays only Flitwick; Griphook is played by Leigh Gill. HBO announced his return on 1 September 2025, the day the Hogwarts Express leaves in the book.

How the books describe Filius Flitwick, and every difference so far, is on the character page.
