Mark Gatiss does go on. He’s been on at me about the Ice Warriors since I took over the show. And, frankly, I’ve been disappointing him. I just wasn’t that thrilled about unearthing yet another old monster. I slightly felt we’d done all the good ones. But then, as I was sitting in my garden on the phone to Mark about Sherlock, he started pitching this story. An Ice Warrior! On a nuclear submarine! Under the polar ice cap. That would have been enough for me to say, “yes, please!” but then he had one more idea that made my hair stand on end.
It’s not for me to tell you what your favourite episodes will be, but this is one of mine.
