Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth will be reunited on the red carpet for the UK premiere of The Hunger Games: Mockingjay - Part 2.
The trio, who are close friends and often joke around together, are set to attend the premiere in London's Leicester Square tonight as they prepare to say goodbye to the Hunger Games franchise.
Also expected are co-stars Elizabeth Banks, Woody Harrelson, Sam Claflin, Natalie Dormer, Stanley Tucci, Julianne Moore, Donald Sutherland and Gwendoline Christie.
Director Francis Lawrence and producers Nina Jacobson and Jon Kilik are also due to be present.
The final film in the four-part franchise, which is based on the trilogy by American novelist Suzanne Collins, will conclude the story of Katniss Everdeen (Lawrence) and her battle to liberate the citizens of Panem.
As Panem descends into a full-scale war, Katniss confronts President Snow (Donald Sutherland) for a final showdown. Realising she is fighting not just for survival but for the future, she teams up with a group of her closest friends - including Gale (Hemsworth), Finnick (Claflin) and Peeta (Hutcherson) - on a mission to free the districts and end the brutal regime.
They stage an assassination attempt on President Snow, who has become increasingly obsessed with destroying Katniss and everyone who opposes him.
This film marks the last chapter in the franchise, which also includes The Hunger Games (2012), The Hunger Games: Catching Fire (2013) and The Hunger Games: Mockingjay - Part 1 (2014).
Visitors to Leicester Square will be able to download an app from 11am, which will guide fans on a treasure hunt around the square searching for clues to unlock content and win prizes. Once the event begins, a real-time feed will update fans with who is arriving at the premiere.
A livestream of the red carpet will also take place on YouTube.
:: The Hunger Games: Mockingjay - Part 2 is in cinemas on November 19.
