Lawrence, 25, who stars as Katniss Everdeen, was happy to hang up her bow and arrow after viewing the last film in the four-part series, The Hunger Games: Mockingjay - Part 2.
She said: “I didn’t feel ready when we wrapped. But when I saw the movie and I saw how amazing it was, it was just the perfect way to wrap everything up and I felt a sense of accomplishment.”
The Oscar-winning actress reunited with co-stars Josh Hutcherson and Liam Hemsworth on the red carpet for the UK premiere of the film in London’s Leicester Square.
The final film in the franchise, based on the fantasy novels by Suzanne Collins, follows the story of Katniss and the rebels as they take on the Capitol in a bid to bring down the regime and liberate the citizens of Panem.
Hutcherson, 23, said: “It feels good to finish it, it feels good to go on to the next thing. It’s been almost five years of my life playing the same character in the same kind of world.
“But it’s sad to say goodbye to the film, because we’re an incredible close family.”
On the film’s popularity, he said: “I think it all comes back to Katniss. I think it’s a character that people really connected with for many reasons. She’s inspirational.”
Sam Claflin, who plays Katniss’s fellow rebel Finnick, said Lawrence, Hemsworth and Hutcherson had let him in on their close friendship - to a degree.
He explained: “I got to know Jen and Liam really well during Catching Fire [the second film], I felt like their third wheel.
“But we were just one big happy family. So as much as those three were three little triplets, brothers and sisters, I felt like the family dog.”
Also attending last night’s premiere were stars of the film including Elizabeth Banks, Woody Harrelson, Natalie Dormer, Stanley Tucci, Julianne Moore, Donald Sutherland and Gwendoline Christie, as well as the film’s director, Francis Lawrence.
Many of the film’s stars payed tribute to the late Philip Seymour Hoffman, who played the role of Plutarch in the film. He died in February 2014 at the age of 46, a week before completing filming on the movie.
Harrelson said seeing him on screen for the last time in the movie would be “strange” adding, “I surely miss him. Great guy.”
Banks said: “It’s sad all over again, you know? It’s a reminder of a terrible loss.”
Producer Jon Kilik said two important scenes had to be changed after the death. As the cast gathered on the red carpet, they said goodbye to the fans who lined the barriers as fireworks and flames shot up into the air, before heading in to the screening.
