Catching Fire, the sequel to The Hunger Games, is set for release in 2013. Because of the first film's great success, it can be assumed that most of the surviving characters will have their cast members return for the sequel; confirmed as of today are Jennifer Lawrence (Katniss), Liam Hemsworth (Gale), and Josh Hutcherson (Peeta). Woody Harrelson (Haymitch), Elizabeth Banks (Effie), Lenny Kravitz (Cinna), Donald Sutherland (President Snow), and Stanley Tucci (Caesar) will likely all reprise their roles from the first film. One casting rumor that has not yet been confirmed is that Robert Pattinson may be cast as former Tribute Finnick; to date, producers have neither confirmed nor denied the rumor. Other casting choices for new characters will be announced by the prodution team as they are confirmed.
Since Catching Fire has not yet begun production, a full cast list is not available. When it is, www.imdb.com is the best place for up-to-date information on movie casting.
