America Ferrera: It was fun and really a nice project that I did over three years. I just sort of stopped in and read some lines in a phone booth—well not a phone booth, a sound booth, but it felt like a phone booth. It was a really good time, and it was unlike anything else you do as an actor in front of a camera. And it was really cool to be a small part in a really big thing. The movie is so beautiful, and I'm so proud to be a part of it. I could never have imagined that the small little sessions I was doing here and there for three years was contributing to this really big, beautiful movie.
RB: Why does it take so long?
AF: Well, I don't really know the details, but when I came in there was a script and we put down lines. And then the animators animate for months and months and months, and then you come in and you have to redo lines to things that they animated, and then they take inspiration from what you did and they animate to your voice, and then you come in and do voice to their animation. It just sort of goes back and forth that way. I think there's a lot of complexities to doing these big beautiful visuals, especially since the film is 3D.
