EW just posted an exclusive behind the scenes clip from the Hunger Games dvd that just premiered at comic con called Katniss on Fire!  The video is not embeddable so click HERE or the image below to watch :

According to EW :

The video is a closer look at the scene where Katniss (Jennifer Lawrence) is tied in a tree, and the fire starts to surround her. Watch director Gary Ross and stunt coordinator Chad Stahelski block out and show Lawrence the path she has to run, and watch how close Lawrence actually gets to the fire. Katniss would be proud.
