Graphic novelist and screenwriter Steve Niles called into Cinematical headquarters this weekend from the Fangoria Weekend of Horrors Convention in New Jersey. We talked all things 30, from the marketing push that will include a series of short films based on the comics, to the ComicCon plans for the film, to the rating -- it's going to be R, for sure -- to the massive sequel potential that exists, considering how much source material there is. (Niles is already thinking about a Dark Days sequel revolving around Melissa George's character, something even she wasn't thinking about when I spoke with her last November) If you're a movie person who isn't familiar with the 30 Days graphic novels or Niles' work in general, he's a major name in comics, having developed many well-known titles and collaborated with scores of other artists.

I was eager to get a sense from him of what kind of vampire effects we're in store for with the film, but he told me Weta is still keeping that information under strict lock and key. Oh well. In addition to 30 Days, he was also ready to talk up Bigfoot, a straight-up horror movie he's jointly developing with Rob Zombie -- a finished script is out to directors. For those who worry about seeing another Bigfoot story that tries to make the beast a sympathetic humanoid, you'll be glad to know that Niles is steering in exactly the opposite direction. Check out the full interview below.

RS: How goes the convention?

SN: So far, so good. It's really funny because I usually do these things on the West Coast, and I walked into this one and it's like, I pretty much ran into the same people, the same vendors, it's very funny. I got here and it was very familiar.

RS: I heard you're taking 30 Days to ComicCon; you're going to be there in person?

SN: Oh yeah, definitely. I'll be there in person, and I'll be doing stuff at IDW, doing some comic stuff, we've got some new 30 Days comics coming out. Sony's got a big thing -- they're going to have a booth there this year. We're gonna be doing a big panel and showing clips, and we might even be unveiling some 30 Days merchandise, some collectible figures or something like that. I'm still waiting to find out, but all day Saturday is going to be '30 Days crazy.'

RS: So have you seen a cut? Is it still in post?

SN: I saw ... I know there's been one test screening since the one I saw. But I hear that they are really close to locking it. Still waiting for word on if we're going to get any re-shoots or anything like that. But for the most part, what I've seen is the finished film.

RS: How much of your draft survived the Stu Beattie draft and the other one? How much of your scripting work is still in there?

SN: An amazing amount of it is. What I used, especially in my version, I used a lot of dialogue from the comic. And all of it's in there. So a lot of my dialogue, a few of my gags, a few things I came up with -- slaughtering the dogs and all of that stuff -- a few things that were just kind of expanding on the idea of the comic -- it all made it. It's really unbelievable. I'm really happy that the three of us are sharing credit because we all became friends and we all worked together, and we all had the same ... we all wanted to make it as close to the comic as possible.
