Teen: How would you describe your character, Renesmee?
Mackenzie: She’s very kind. She also is shy. And she is half of a vampire, [so] she grows really fast. One hour she’ll be a baby, and the next hour she’ll be a toddler. It’s weird. And she’s really, really smart.
Teen: You weren’t allowed to read the Twilight books, but you were allowed to watch the movies. Why is that?
Mackenzie: I’m just not old enough.
Teen: But you were old enough to see the movies. What’d you think of them?
Mackenzie: Yes. I thought they were really cool. I liked them.
Teen: What was it like the first time you met Rob, Kristen and Taylor?
Mackenzie: The first time I met Rob and Kristen, I was in the hair and makeup trailer for my wig fitting and I don’t remember what they were doing — I think they were getting their hair done or something — and I just said, “Hi, my name’s Mackenzie.” I met Taylor on the first day I got to be on camera, and we were doing some scene together. He said “Hi.”
Teen: What was your favorite scene to film with Taylor?
Mackenzie: I had a lot of fun filming all the scenes, so it’s hard to pick one. Riding Jacob wolf; that’s actually my favorite scene. I really liked that one. It was like a mechanical bull kind of without the head. It was all furry… But Taylor wasn’t there.
Teen: You’ve done some Tae Kwon Doe and Taylor also does martial arts. Did you ever talk about that?
Mackenzie: We did talk about it. The first time I told him I think I was a blue belt, and now I’m a junior black belt. We did push-ups.
Teen: Was it a contest?
Mackenzie: Yeah, it was really fun. I don’t remember who won, but I remember doing a lot.
Teen: You guys played football, too?
Mackenzie: Well, we tried. He threw it really really high and far, and I would go catch it, then I would throw it, like, 4 inches.
Teen: Off-camera, what were some of your favorite moments with the cast?
Mackenzie: I went hiking with Kristen and that was really fun. And me and Taylor we were all playing games and my mom showed ['em] something on her iPhone and they were playing that forever. It was really funny.
Teen: Robert said you got a lot of money from the cast for swearing around you…
Mackenzie: Well, I started hearing some oopsies around set and I decided that I should start a swear jar. It’s just like a little container with stickers on it.
Teen: And you just told them this is something they had to do or…?
Mackenzie: Actually, they all wanted to do it because they have a problem. They need some help.
Teen: Who was the biggest culprit?
Mackenzie: I’m not gonna say!
Teen: There was an interview where you said you wanted to be a movie director. Is that still something you want to do?
Mackenzie: Oh yeah.
Teen: What types of movies?
Mackenzie: I haven’t really thought about that. I guess I’ll say all movies.
Teen: You said you like action movies, so maybe that?
Mackenzie: Yeah! I’ll be doing a lot of action movies.
Teen: Do you have any embarrassing set moments?
Mackenzie: I fell a lot. I remember tripping and falling, but I do that all the time… Sometimes I would be doing a scene and I would stumble and I’d have to start over.
Teen: What music are you into?
Mackenzie: Right now, I’m into One Direction. They’re fun.
Teen: Who’s your favorite?
Mackenzie: All of them!
