First up we'll take a look at what the main cast (and interspecies love triangle) of Edward (Robert Pattinson), Bella (Kristen Stewart) and Jacob (Taylor Lautner) had to say about their second outing in the Twilight Universe. I've remixed Collider's interview with each actor into a semi-coherent shared train of thought. Take a look:
Pattinson: It’s funny about ‘New Moon’. When I read ‘New Moon’ it gave me ideas about how to play the first one [Twilight] and it’s the one that I connected to the most and the one that humanized Edward the most for me as well. In the first one he still does remain from beginning to end an idealistic character but in the second one he makes a mistake that’s acknowledged by everybody including himself. Also he’s totally undermined by more powerful creatures and he’s undermined emotionally by people as well. I think that’s what humanized it. Since I’ve read that book I’ve always kind of liked him as a character. I try to play that same feeling throughout the first one and after the third one, as well, trying to get some kind of element of an all powerful person or almost all powerful person, the kind of hero of a story who just refuses to accept that he’s the hero. I think there’s something admirable there. I don’t know if I really made any sense.
Stewart: I had a really good time on this movie. It was intense. Just because of the nature of the story it goes in a completely different direction. We undermine the first. We establish a very ideological of love and basically tell our main character, our main protagonist that she was wrong and it’s like, ‘Where’s our story?’ You’re going to be left if Edward’s not there. What I really love about ‘New Moon’ is that you see this girl build herself back up and by the time she makes this sort of rash decision to spend eternity with a vampire she’s in a position where you actually believe her. You’re like, ‘Okay, you’re old enough, your mature enough to know. You’ve lived life.’ She grows up. I don’t know what I’m talking about anymore.
Lautner: ...Yeah, Jacob transforms a lot in ‘New Moon.’ Not only physically, but mentally and emotionally as well. So it was a matter of getting to the gym and eating the right foods and a lot of it. But also, reading and studying the book and my character over and over and over again so I could have his character down as well. Because he changes in many many different ways...basically my job was to continue what I started in ‘Twilight,’ which was this extremely happy, friendly, outgoing guy. Best friends with Bella. And I had to continue that for the first half of the film, but as soon as I transform, I snap and I become a completely different person. I’m dealing with my issues and it’s really hard for me.
And of course, regarding the often-debated subject of who would win in a fight between vampire Edward and wolf-boy Jacob:
Pattinson: [laughs] I don’t know. I did hear the other day that Taylor had agreed to an interview where the interviewer was going to fight him. I don’t think that I’d ever agree to that and also looking at Taylor’s martial arts videos from when he was like nine I really wouldn’t want to do anything. Maybe if I had some kind of weapon. Edward and Jacob? I don’t know. I think it’s actually a fact that Edward would win. I think. If I’ve read the books correctly. So I guess I can hold onto that for my ego.
Lautner: Oh man. I don’t know between me and Rob. He actually does a lot of boxing in his time off, so it might be a good match-up. Jacob, we were actually discussing this on set, it’s funny we were like ‘who would win in a fight between Jacob and Edward,’ because there’s a scene outside Bella’s house where Edward grabs my shoulder and he’s mad at me and Jacob doesn’t take that. So he takes his arm and rips it off. And at that moment, Jacob would transform into a wolf and we’re having this discussion that got really deep, we’re like ‘if I were to poof into a wolf right now, what would happen? Who would win?’ I don’t know, our discussion points were like ‘usually, we’re with our pack so if I’m without my pack, am I gonna be weaker?’ So I honestly don’t know. That discussion is still up in the air. We should probably get Stephenie Meyer on the line and ask her.
There is a ridiculous amount of material in these interviews, so if you're really hungry for the full transcripts, I'll point you to where you need to go:
