Supervising producer Megan Parlen agrees.

"The topic initially seemed outwardly ridiculous and even scifi, but there is so much fascinating science behind it, like the epidemiology, how certain viruses are spread, and the nature of consciousness," she says. "So it turned out to be a science-heavy but really fun episode. We were all very surprised."


She added: "The zombie episode presents some troubling issues, like how vulnerable we are to being controlled, and how we're becoming increasingly susceptible to technology."

In addition to zombie plagues, Freeman believes technology could turn us into mind-controlled zombies, like the Borg. I asked him why this scenario concerns him so much.


"Let me ask you a question, George," Freeman said. "Do you use a cell phone? How do you feel when you can't find it."

"Like I've lost a part of my body," I replied.

"Exactly — a development that's happened within the last 10 to 15 years," said Freeman. "Sometime before that, life was going along pretty good. The thing that our technology does, is that it allows us to rely on machinery to do the thinking, the physical labor. The technology will eventually — and Stephen Hawking agrees with me on this — become the governing force."
