Jennifer Lawrence has a blast answering questions from avid fans of "Hunger Games" at Comic-Con 2015. They were eager to know the details of the final chapter of the franchise, "Mockingjay Part 2."

Conan O'Brien hosted the event and it was the first and the biggest movie panel for the franchise. It was held at Hall H of the San Diego Convention Center with a seating capacity of 6,500, The Wall Street Journal has learned.

The event gave fans, many of whom came dressed up as their favorite heroine of the film, excitement when director Francis Lawrence introduced the latest trailer for the film. Lawrence begged fans not to record the trailer and he even promised that Katniss Everdeen is going to be "more active." In "Mockingjay Part 1," many opined that Jennifer Lawrence' character lacked action and enthusiasm.

Director Lawrence assured fans that for "Mockingjay Part 2," Katniss is going to "get into action." He added, "She was a bit sidelined in the last movie and going through her issues. The director informed fans that Katniss is really coming after President Snow and that the film has "some real battle footage"

Variety reported that Jennifer Lawrence was quite emotional to see it all coming to an end. The actress revealed that she "broke down and cried" when she began shooting "Mockingjay Part 2." The actress said, "These movies changed my life. I feel like it will always be a part of me."

It was a fun-filled day for both the fans and the stars of the film. The fans even asked the cast to do the "iconic whistle" from the film.  Liam Hemsworth and Josh Hutcherson revealed that they've tried doing it several time, but they always ended up sounding like the theme from "The X-Files."

"Mockingjay Part 2" hits theater on November 20.
