The Oscar-winning actress, who has spent the last five years playing Katniss Everdeen in the hit fantasy movies, admits she couldn't control her emotions when the final film , 'The Hunger Games: Mockingjay Part 2', completed shooting in East Berlin, Germany.
She told Entertainment Weekly magazine: "It was so emotional that I was completely numb and dead inside."
As for Jennifer's co-star Liam Hemsworth, the Australian hunk has revealed he was drunk on the final day of filming.
Liam, 25, and co-star Josh Hutcherson, 22, had already finished shooting their last scenes the day before and indulged in a bottle of scotch before returning to set the next day.
Josh said: "Then [the next day] we came to the set because Jen and Woody [Harrelson] had a last scene together and we wanted to watch the last couple takes.
"Then they called wrap and we kind of sat there on the steps in this room and we just held each other."
While the trio said a tearful goodbye, good-humoured Jennifer, 25, admits they were reunited just a week later.
She quipped: "And then a week later we were all together and we thought, 'Was it weird that we got so dramatic?' "
