In the film adaptations, Flitwick is portrayed by Warwick Davis. Rowling said: "I must admit, I was taken aback when I saw the film Flitwick, who looks very much like a goblin/elf (I’ve never actually asked the film-makers precisely what he is), because the Flitwick in my imagination simply looks like a very small old man." However, Rowling mentions on her official website that Flitwick is human, with "a dash of goblin ancestry." His on-screen appearance changes noticeably in "Harry Potter and the Prisoner of Azkaban", in which he takes on a more human and less elf-like look, with slicked-down dark hair and moustache. According to Davis, the moustachioed character was originally not supposed to be Flitwick; Flitwick was absent from the script for "Harry Potter and the Prisoner of Azkaban", but "the producer" (presumably David Heyman) added the new character (as the conductor of the school choir and orchestra, credited as "Choir Master") so that Davis could still appear in the film. "Goblet of Fire" director Mike Newell preferred the new look, "and from that moment, the character became known as 'Flitwick'." Flitwick was born on 17 October.
