IronE: (what is most demanding about The Walking Dead) The show is so physically demanding. I would have to say the scene we did with the well walker. We had to catch the water pump from falling in the well -- we had to do that so many times. And I was on my backside and I had to kick and claw. The water pump was fake -- but it was quite demanding and really tough because we did it over and over again. By the end of the day, I was exhausted...it was scorching hot too.
