The Hunger Games: Catching Fire actor Liam Hemsworth, who plays Gale, reveals in a new interview with USA Today that he was injured while filming last week.

“I twisted my knee,” Hemsworth revealed. “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.”

The injury may’ve been due to an action sequence, which Hemsworth says there are more of in this sequel. “There’s a bunch of action in this one. All of the characters have much more action than they did in the first one.”

Elsewhere in the interview, the actor says he lost a little bit of weight to get in shape for the character who didn’t enjoy watching Katniss and Peeta get close in the first Games.

We hope Hemsworth made a speedy recovery and stays safe for the duration of the shoot! The cast and crew are currently in Atlanta for the next couple months, then will wrap filming in December in Hawaii.

The Hunger Games: Catching Fire hits theaters November 22, 2013. See on-set photos of the District 6 cast filming in Atlanta last week which Hypable brought to you exclusively.
