There’s a relatively recent interview with Garret at CraveOnline.com. Some quotes below.

About the big death of season 2.0 on Terminator:

First question is how did you feel when it turned out to be you?

Garret Dillahunt: I was nervous at first. None of us knew at Comic Con. We were all being really cool about our new show and then they were like, “One of these people will die.” And you were like, “What?” It was like the last supper all of a sudden. Is it I? Is it I, lord? Then it was me but then they told me also right away that I’d be this different thing which hadn’t completely evolved yet. I was kind of sad because I liked Cromartie. I liked playing Cromartie. I liked the simplicity and the directness of him and getting to do all those cool things, but John Henry’s going to be pretty cool.

So did it occur to you, as it did me, that you were the one character who could still be alive via his exterior?

Garret Dillahunt: Exactly, really could it be killed? Was he ever alive? But I’m happy about it. Now I get to be this sort of super powered baby turned loose in the world.

How is this totally new character for you?

Garret Dillahunt: Well, I’m getting anxious to get out of that computer room. They clip this thing into my head, this chord and you feel very limited but I understand the necessity for it. He’s got to learn so much he’s sucking all this information out of the internet and the world and television, just cramming his head full of this stuff and trying to understand what it is to be human. So I think the opportunity is kind of limitless. It’s an interesting way for the writers to explore what it is to be a human almost.

Do you know what kind of big finale we can expect this season?

Garret Dillahunt: I don’t. I wish they’d tell me. They just handed me some talking points. I think it changes too. I think they have an idea of what they wanna do and then it’ll evolve into something slightly different by the time we get there. It’s kind of like how Deadwood was because I remember David would come up to me like, “Yeah, then your character and the Doc are going to have this whole relationship and you’re going to talk about Catullus.” I’m like, “What happened to that? I never saw that.” Oh, well, it didn’t work out. It’s a little bit like that. They have so many things they’re trying to tie up that some things fall by the wayside.

About The Road:

What do you play in The Road?

Garret Dillahunt: Well, no one has names. I don’t know if you read the book. I loved it. Some of the scenes are harrowing but it was so beautiful too. In a way, the world has been so pared down, it’s a very simple story and it raises a lot of questions about what you would do in that situation. It’s kind of like Terminator in a way. But no one has names. Viggo Mortensen plays The Man. Cody Smit-McPhee plays The Boy. So it’s The Man and The Boy moving through the world and they meet The Old Man, The Thief, The Woman. No one has names, no one uses them. I played The Gang Member. We meet up sort of in the first quarter of the novel. I make some decisions about Viggo and I decide that he’s weak and I can take from him what I want and we have a fight about that.

So we’ll see you and Viggo with supplies?

Garret Dillahunt: Oh yeah, that’s what the whole story’s about. You’ll see. It’s just like an endless search. It’s like we’re animals who are pawing through the snow for some grass. The search for food never stops. The search for food motivates all actions in the movie from the bad guys and the good guys.

And about The Last House on the Left:

That’s the question. Is it as hardcore as the original?

Garret Dillahunt: I don’t know if it’ll be seen as being as hardcore because that was something new at the time. There’s something about that story that’s also very primal. I think people f*cking with your family is a real primal thing that happens to all of us. The most mild mannered of us can vision real violence if someone threatens our families or people we love. It’s like what am I capable of? Maybe I’ve never been in a fight in my life but I’m not going to rest until I’m dead to try to stop you from doing something to my family. It thrusts this normal group of people into that very situation. I think there’s a lot of sympathy for Krug in a way. You can see how life has frustrated him but he’s taken it out the wrong way. But the end result, which I think is rare in a horror movie, I really cared about the victims, but you really care about this family which is odd. I didn’t know that it was odd until it happened when I saw it. It left me feeling mugged and beat up. I felt tired after I’d seen it. It’s just relentless cruelty and tension, just relentless tension. It went by really fast and it’s tested really well. The audience has been skeptical too because there’s been a lot of people who are fans of the original that thought this was a horrible idea. I don’t think they’ll be disappointed.

Sounds like they went for it.

Garret Dillahunt: Yeah, boy, ugh. There are some scenes you’re just like why? What’s the purpose of that?

You weren’t sure how it would go over now, since we’ve seen so much. Did they have to up it, because that rape scene is still so awful you feel bad for watching it.

Garret Dillahunt: Well, I think that’s the most important thing. You’ll see a lot more blood in Saw movies or something like that than you will in either of the Last House movies. I kind of think it owes more to The Virgin Spring which is the original source material, the Bergman movie. There’s a scene in there where these shepherds have raped this girl and then they’re sort of horrified by what they’ve done. One of them kicks some dirt, like he can’t take the face. He sort of shovels some dirt and there’s just this dirt on her face. She’s in this awkward position and it’s just so pale, and half under a bush. There’s an emptiness about the movie that’s different. I don’t even know if it’s a horror movie is what you should call it. I don’t know what it is.
