The Walking Dead - Season 2 - Interview with Reedus, Holden & Hurd @ Comic-Con

Tell us something about the new season that’s been really fun to shoot
HOLDEN: Oh everything’s been fun to shoot
HURD: Oh well I think that the highway, I mean that was really big. We actually closed down a Georgia highway for a number of days. We were on the local news because we caused traffic jams.

Your own Carmageddon.
HURD: Except it was a real Caramgeddon (laughs).
HOLDEN: It was a real Carmageddon and a helicopter kept coming above the freeway and circling.
HURD: And we were like “Wait wait wait, there were no helicopters in the zombie apocaplypse!”
HOLDEN: And we though “Hm maybe we should point the gun at them but then figured they’d probably really shoot us.”

How has it been having the new cast members? Have they had any questions for you coming on the show?
REEDUS: They all came on going “Oh. My. God I love this show.” They all knew the characters really well—all of our characters. They came in with hugs. They fit right in and they bring their own unique flavor to the soup.

Can you talk about filming that highway scene, being underneath all those cars?
HOLDEN: I’m trying to figure out what I can say to that I’m allowed to say to you!
HURD: Well there were lots of zombies
HOLDEN: I wasn’t under a car. There were some terrifying sequences with some zombies.
REEDUS: It got sloppy.
HOLDEN: It got sloppy in a really fantastic way. You’re going to love it when you see it. But I gotta stop there.

Anything you can add to that, Norman? Something fun about that scene?
HURD: You got to ride a really cool motorcycle.
REEDUS: I ride a dope motorcycle. It’s a Triumph. It’s sort of the scout-mobile for the rest of the caravan.
HURD: It’s interesting you see the RV break down. It actually did break down, remember? It wouldn’t actually move for a week—it had to have its engine completely rebuilt. So, sometimes art imitates life and sometimes life imitates art. That happens a lot on our show because the zombie apocalypse hasn’t happened yet.
