Liam Hemsworth has suffered an injury on the set of The Hunger Games: Catching Fire.

The actor has revealed he was injured during a dramatic stunt on the set of the second big screen adaptation of the popular trilogy in Atlanta, Georgia last week. "I twisted my knee. I try to just fight through it. There's so many people standing around waiting for you to do your thing. You feel sort of obligated not to let everyone down. There's a bunch of action in this one. All of the characters have much more action than they did in the first one," he told USA Today.

The 22-year-old Australian actor also revealed he adopted a healthier diet to slim down for the new movie, which began filming last month: "It's The Hunger Games. My character needs to look hungry. A little bit."

Liam, who is also filming the thriller Paranoia, said he is looking forward to taking a break as he has spent much of the last year working. "I haven't had a break in about a year. I've kind of shot one film to the other. And have had to prepare for each while shooting another. It's been a tremendous workload. But I feel so lucky to be where I am. I'm so thankful," he said.
