Ask an Authority: Interview with British Horror Historian John Hamilton

He's interviewed everyone from Anna Massey to Gordon Hessler and has written more about British Horror cinema than most people will ever learn. The author of (among many others) "Beasts in the Cellar: The Exploitation Film Career of Tony Tenser" joins us for a chat about the best decade of British horror, the films we form attachments to, the most underrated country for horror, and his latest book: "Witches, Bitches and Banshees".
