The cast of 'The Hunger Games' keeps growing.

The latest addition is Elizabeth Banks, who is in talks to join Lionsgate's adaptation of Suzanne Collins' popular book series, according to The Hollywood Reporter. Already cast are Jennifer Lawrence in the lead role of Katniss Everdeen. Josh Hutcherson and Liam Hemsworth are cast as love interests, while relative newcomers Amandla Stenberg and Dayo Okeniyi were cast earlier Monday as Rue and Thresh, respectively.

Banks will play Effie Trinket, a pink-haired showbiz type who becomes the handler of Katniss.

The story takes place in the not-too-distant future, when the U.S. has collapsed and has been replaced by Panem, a country divided into the Capitol and 12 districts. To keep the subjugated citizens entertained, each year two young representatives from each district are selected by lottery to participate in the brutal Hunger Games, which are broadcast throughout the country, with all citizens required to watch. The first book follows the adventures of two contestants -- Katniss and Peeta -- as they become gladiators in the futuristic reality show.

Gary Ross is directing the movie, which is scheduled for a March 23, 2012, release.
