Brian Reitzell knew I am a huge Siouxsie Sioux fan and have seen her in concert more times than any other artist in my life. We knew that she was a fan of the show, and we reached out to see if she'd be interested in writing a song. Essentially, she hasn't had a single in eight years, and she said she hadn't been inspired to write in a long time, but that Hannibal had inspired her and she would write a new song. It was an incredible honor. I told her it should be a love song between Will and Hannibal. She came back with this wonderful Bond theme of a ditty, and I just said that has to go over the finale. It was pitch-perfect.

Then it became the battle over... how do we pay for it? We didn't have any money left in the budget, and the studio wasn't going to put any more money into the show than they already had. I went to NBC and Sky, who are our American and UK broadcasters and said, "I know the show is canceled... and it's absolutely unheard of for a showrunner to come back to you and ask for more money for a show that has no further revenue potential for you. But it's Siouxsie Sioux and it's an honor and it's her first single in eight years." They both said, "Yes, absolutely, we'll split it right down the middle, and we're doing this because we love you, we love the show, and we love Siouxsie."
