"One of the challenges of the show has always been trying to be surprising, and that was easy to do when nobody was watching it. Now that people have started watching it, they get ahead of us. We've all started really guarding the material, just to make it fun for the audience."

To be honest, I would have to say that there was a certain burden in working with Arnold, a big action star. I am aware that Arnold is loved by the American audience, but rather than focusing on working with Arnold, what I focused on was expressing the character, Sheriff Owens, through Arnold the actor and knowing that Arnold and my idea about Sheriff Owens coincided and that it was about Owens protecting a certain value and justice, I focused more on that aspect that helped me to be more comfortable in working with Arnold.
