The first time I called the CDC, I said that I wanted to talk to someone about possibly designing a zombie virus. …So every time I came up with a new iteration of Kellis-Amberlee, I would call back and say, “If I did this, this, this, this, this and this, could I raise the dead?” And every single time they would say, “No.” And I’d say, “OK,” hang up, and go back to working. After about the 17th time, I called and said, “If I did this, this, this, this, this, this and this, could I raise the dead?” And got, “Don’t … don’t do that.” At that point, I knew I had a viable virus.
