I can't imagine Hunger Games, even with its very popular books, being nearly a success that it's been without Jen Lawrence being the perfect person to play that role - a very modern celebrity, a very down-to-earth, accessible, celebrity.

In the evolution of the [The Hunger Games] movie, Gary [Ross] and I talked a lot about tonal bandwidth and making sure that the look and feel and style and choices of the movie stayed within a certain consistent bandwidth.

The hiring of Phil Messina, the production designer, was a big decision. He's so gifted, and his ideas were always so smart and rooted in American history and architecture. Nothing feels like it's not us, or couldn't be us, and I think that's very important.

Little decisions were made, every day. In this movie [The Hunger Games], we really focused on Cinna and we didn't get time to focus on the other stylist.

We both [with Suzanne Collins ] felt strongly that you wouldn't want to age up the characters, no matter the age of the actors playing the roles. They should be playing the age that they are in the [Hunger Games] books. It would let people off the hook, if you said, "Well, instead of 12 to 18, why don't you make them 18 to 25 or 16 to 21?" If you don't stay true to the horror of the fact that they are 12 to 18, you're not doing justice to the book.

It can really vary from movie to movie what the producer's role is and there are all kinds of producers. There are line producers who do a lot of the nuts and bolts work on the set.

If the movie [The Hunger Games] were stylized violence that was pretty and fun and cool, which is great when you go see 300 or The Matrix, it would just be out of sync with the fact that they're kids.
