"I had to do 10 'wall runs,' where you run at the wall as hard as you can to get traction," Lawrence -- who plays Katniss Everdeen, teen huntress and Hunger Games upstart in "Games" -- told The Hollywood Reporter. "I ran at it and my foot didn't go up, so I caught the wall with my stomach. My trainer thought I had burst my spleen. I had to get a CAT scan and go into a tube where they put this fiery liquid in your body."
Thankfully for "Hunger Games" fans, Lawrence was just bruised and production was able to go off without a hitch. Not that filming "Games" didn't offer other complications. The cast and crew had to compete with 100-degree weather, drenching rainstorms and even bears. 300 of them, reportedly, that lived in the woods where "Games" was shot.
Based on the mega-popular book series by Suzanne Collins, "The Hunger Games" -- the first of four planned films -- arrives on March 23.
