Anthony Head is a British actor best known as his role as Giles in Buffy the Vampire Slayer when he went by his full name, Anthony Stewart Head, and more recently as King Uther in Merlin. He also had a short role as Will's terrible dad in The Inbetweeners Movie.
He also has an album, played Nathan in the Rock Opera Repo! The Genetic Opera and served up glorious sides of ham as the evil guardian Mr Gently Benevolent in Radio 4's Bleak Expectations. He also played Michael the Prime Minister in sketch show Little Britain, and appeared in the Doctor Who episode "School Reunion" as that episode's villain, Mr. Lucas Finch.
Long before he was Giles, he was most recognisable for being half of an insufferably smug Will They or Won't They? couple flirting over instant coffee in commercials for Nescafé.
Oh, and he played Dr. Frank N. Furter in at least four different productions of The Rocky Horror Show (the original theatrical musical that became The Rocky Horror Picture Show): in the 1990–91 West End revival, again in the summer of 1995 at London's Duke of York's Theatre, a 3 May 2006 tribute show at London's Royal Court Theatre, and a 14 October 2000 production at the Hard Rock Hotel and Casino in Las Vegas. His rendition of "Sweet Transvestite" from the West End production was released as a single in 1991.
In 2007, Joss Whedon announced that Head was poised to resume his role as Giles in a BBC TV Buffy Spin-Off entitled Ripper, but the final negotiations apparently fell through and the show was never made. Characters and plotlines developed for Ripper were later adapted for Dark Horse's Angel & Faith comic book.
He is the brother of actor/singer Murray Head.
