Liam Hemsworth revealed that he twisted his knee whilst filming The Hunger Games: Catching Fire.
The actor is currently on set in Atlanta reprising the role of Gale in the second Hunger Games movie - which is due to hit the big screen next year.
And while Hemsworth picked up a bit of an injury he toughed his way through the pain to continue.
Speaking to USA Today the actor said: "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."
Jennifer Lawrence and Josh Hutcherson are also reprising their roles of Katniss Everdeen and Peeta Mellark while Francis Lawrence is in the director's chair.
And while not giving anything about the movie away Hemsworth said that there is much more action this time around.
"There's a bunch of action in this one. All of the characters have much more action than they did in the first one."
And Hemsworth has been busy this year as he has already completed work on Empire State and Paranoia.
The Hunger Games: Catching Fire is released 22nd November 2013.
