Fans of the book fear the film version of Suzanne Collins' hard-hitting trilogy will be tamer than the novels to gain a mainstream appeal.
Despite the eagerly-awaited movie receiving a PG-13 rating in the U.S., the Oscar-nominated actress insists it still contains plenty of visceral moments on screen.
She tells BBC Breakfast, "We had to have a PG-13 rating but violence is at the heart of the movie, because it has to make people angry enough to start an uprising. We couldn't water down the movie. The PG-13 rating helped us, because it made the violence really quick (on screen)."
It was announced on Tuesday (13Mar12) that movie bosses were forced to re-cut the film to land a 12A rating in the U.K.
