Julianne Moore on 'Mockingjay' - "We have a Huge Responsibility"

Julianne Moore has admitted that her role as President Alma Coin in the upcoming The Hunger Games: Mockingjay comes with a "huge responsibility to the book".

"There are some things that have been written that the fans are adamant be there," Moore told Digital Spy exclusively. "We're taking that responsibility very seriously."

Moore also said playing US politician Sarah Palin in Game Change didn't influence her portrayal of Mockingjay's ruthless President.

"They don't have a whole lot to do with one another. When you're playing a real person, all your research is really about how that person speaks and moves and is physically."
