Christopher Lee became a fan of metal in the early Seventies when he first heard Black Sabbath, whose guitarist Tony Iommi reciprocated the respect the actor had for his band and the genre it spawned.
In a 2013 promotional video for one of Lee's own albums, he told Iommi, "You are the father of metal", to which the guitarist replied, "But you're the one that started it, really, because we used to go watch Dracula and the horror films you did and that's what influenced us."
