The Hunger Games: Catching Fire stars Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth and will be in cinemas from November 22.

The Hunger Games: Catching Fire is an upcoming American science-fiction adventure film based on Suzanne Collins' novel, Catching Fire, the second installment in The Hunger Games trilogy. The film is the sequel to The Hunger Games, and the second installment in The Hunger Games film series, produced and distributed by Lionsgate. Francis Lawrence is set to direct a screenplay from Simon Beaufoy and Michael Arndt. Academy Award winner Jennifer Lawrence returns as Katniss Everdeen along with Josh Hutcherson, Liam Hemsworth, Woody Harrelson, Lenny Kravitz, Elizabeth Banks, Stanley Tucci, Donald Sutherland, Toby Jones and Willow Shields also reprising their roles.

Months before the release of The Hunger Games, Lionsgate greenlit the second film and Gary Ross, director of the first film, was expected to return as director. However, on April 10, 2012, he announced his departure from the project due to the tight and fixed production and on May 3, Francis Lawrence was hired as the film's director. Throughout July and September 2012, the film's supporting cast was filled out, with Phillip Seymour Hoffman, Sam Claflin, Jena Malone, Lynn Cohen, Meta Golding, Amanda Plummer and Jeffrey Wright brought in to portray key roles. Filming began September 10, 2012 in and around metropolitan Atlanta, Georgia before moving to Hawaii.
