Sam Ly, Leigha Hancock reaped by District 7 for 'The Hunger Games'

Only four districts' tributes remain to be cast for 'The Hunger Games."

District 7 has joined its neighbors who have already reaped their tributes for "The Hunger Games," with  newcomers Sam Ly and Leigha Hancock joining the film's growing cast.

"The Hunger Games," based on Suzanne Collin's best-selling novel trilogy, follows the title event, an annual battle to the death involving two children from each of the 12 districts of Panem.

While Hancock does not have any previous credits, Ly had roles in the direct-to-video films "Tremors 4: The Legend Begins" and "Timecop: The Berlin Decision." Like most of the other tributes, neither of their characters are given names and the roles are small ones.

This leaves District 2, 8, 9 and 10 as the only ones remaining to be cast. District 2's tributes Cato and Clove are the only named ones left.

Ly and Hancock join Jennifer Lawrence ("Winter's Bone"), Josh Hutcherson ("Bridge to Terabithia"), Liam Hemsworth ("The Last Song"), Elizabeth Banks ("The Next Three Days"), Paula Malcomson ("Sons of Anarchy"), Leven Rambin ("All My Children") and fellow newcomers Willow Shields, Jack Quaid, Amandla Stenberg, Dayo Okeniyi, Ian Nelson,  Kalia Prescott, Jacqueline Emerson, Chris Mark, Ethan Jamieson and Tara Macken.

The film will be directed by Gary Ross ("Seabiscuit," "Pleasantville") based on a screenplay from Bill Ray ("State of Play"). It is set for a March 23, 2012, release and is expected to be rated PG-13.
