TV starlet Leven Rambin (“Grey’s Anatomy”) and Jack Quaid are the latest to sign up for Lionsgate’s big screen adaptation of author Suzanne Collins’ young-adult series “Hunger Games.” They join a cast that includes Jennifer Lawrence (X-Men: First Class), Josh Hutcherson (Journey 2: The Mysterious Island), Liam Hemsworth (Knowing), and Elizabeth Banks (The Uninvited).

Hunger Games finds child survivors of an economically and socially collapsed America competing in televised death games in a new country named Panem. Two kids from each of Panem’s 12 districts are chosen by lottery each year to participate. Rambin and Quaid will portray District One players Glimmer and Marvel, respectively.

Rambin, a 20-year-old Texas native, is best known to genre fans as Riley Dawson on the short-lived Fox series “Terminator: The Sarah Conner Chronicles.” Quaid’s claim-to-fame is that he fell out of Meg Ryan’s vagina around the time she was hitched to Dennis Quaid.
