A film company called Color Force has acquired film rights to the Hunger Games. According to the International Movie Database, the film is projected to be released in 2011.
Color Force seems to be a relatively new company, and little to no information is available.
It seems that Nina Jacobsen, former president of the Buena Vista Motion Pictures Group, is either working with or owns Color Force. Jacobsen has an extensive history as a film executive, overseeing projects for films such as Pearl harbor, The Chronicles of Narnia, the Pirates of the Caribbean, Signs, and the Princess Diaries, among others.
Update: Lionsgate will be working with Colorforce on this film.
