The American-made show, which spanned 144 episodes over seven series, aired on BBC2 between 30th December 1998 and 18th December 2003, starring Sarah Michelle Gellar as the eponymous heroine, with Anthony Head as her Watcher, Rupert Giles, and aided by her "Scooby Gang" of friends. It won three Emmys, spawned the spin-off TV series Angel, and proved to be hugely influential on TV plotting and scripting.
Author and novelist Naomi Alderman has made the radio special to examine its impact and, as she puts it, "why there are so few 'daughters of Buffy': strong and complex fictional creations, who aren't simply the sole female lead in a predominantly male cast."
Interviewed for the half-hour programme, which goes out at 7.15pm, are the show's creator Joss Whedon, along with Anthony Head, writers Neil Gaiman and Rhianna Pratchett, TV executives Jane Root and Susanne Daniels, and fans Blake Harrison and Bim Adewunmi.
The show will be available to listen to live worldwide via the BBC Radio 4 site and afterwards via the specific programme site.
