It is inarguable that Jennifer Lawrence's fame can be credited to her role as Katniss Everdeen on 'Hunger Games.' While she appears courageous in the dystopian movie, filming the scene requires strenuous trainings which sometimes lead to injuries. Here are 5 facts about Jennifer Lawrence while filming 'Hunger Games':

1. She nearly burst her spleen.

On the last training day for 'Hunger Games,' Lawrence had to run full-speed into a wall. However, it did not turn out successful.

"I had to do 10 'wall runs' where you run at the wall as hard as you can to get traction. 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," she told Hollywood Reporter.

Josh Hutcherson likewise had an injury when Jennifer Lawrence told him that she could kick over his head. She tried but her foot accidentally hit Hutcherson's head giving him a concussion.

2. Her favorite costume can be seen in 'Catching Fire.'

Joining the Hunger Games temporarily made Katniss Everdeen a "puppet" of the Capitol. Her glam team needed to dress her up in flamboyant costumes. Nicholas Hoult's girlfriend admits that her favorite costume is the gold dress which she wore during the Tribute Parade.

3. There used to be a "swear jar" on the set.

The filming for 'Hunger Games' lasted for four months in Asheville, North Carolina. This made the cast members grow close to each other. Apart from pranks and hotel sleepovers, they likewise came up with a "swear jar" wherein adults who curse would have to put in money inside it.

Director Gary Ross revealed that half of the jar's money came from Lawrence: "She's fantastic but she swears like a sailor."

4. She went deaf while filming 'Catching Fire.'

There was a scene wherein Lawrence had to dive into stagnant water. The stunt gave her a double infection which left her one ear deaf for a week.

5. Her famous braid only took 20 minutes to do.

Katniss is known for her signature braid and while actresses typically need hours of primping, her hairstyle only took 20 minutes to style. Nonetheless, there were 35 full-time makeup artists hired for the film.
