With the release this week of Chris McKay's new film Renfield, Matthew Sweet looks back at the many appearances of Dracula on our screens and at the music the count has inspired. The programme looks back to some of the earliest cinematic manifestations of Dracula, from the 1920s, including the silent classic 'Nosferatu' and brings things right up to date with scores from Wojciech Kilar, Popol Vuh, Dan Jones, Philip Glass, James Bernard, Mark Isham, John Williams and Marco Beltrami.
