Liam Hemsworth 'Hunger Games' Premiere

When asked what he expects fans to take away from the action thriller, Liam Hemsworth brought up his favorite charity. "I am an ambassador for the Australian childhood foundation which is all about protecting children from getting abused," he said. "A big part of this is kids that are going through horrific things, so I hope people can take something away from that."

The actor also tells THR what weapon he would want with him if he was forced to participate in a real Hunger Games.
