The Walking Dead - Q&A with Andrew Lincoln

Q: What was the bar scene like in Episode 8?
A: That was an incredible scene! We were so lucky to get such cracking actors. And we didn't play the problem, we just played the fact that this is a reunion of human beings. The tension is inherent in the fact that they encounter this other group.

Q: Rick's presence at the farm has been described as antagonistic this season. Do you ever feel like you're a bad guy on your own show?
A: Yeah, I think I do a bit. I don't normally see it like that though, because you never look at your own character as the problem. I'm appealing to this man's spirit.

Q: Was the scene when Rick had to kill Sophia a difficult one to shoot?
A: I was talking about this the other day thinking, my goodness who'd have thought I'd build a career as a child killer in a huge internationally acclaimed show? What does that say about the state of things! Look, as an actor I was even going, "Please let her be alive." It's a gut-wrenching moment. Conversely, it's a brilliant beginning to the second half of the season, which is a much darker and more dangerous exploration of these characters.
