Liam Hemsworth has been cast in The Expendables 2, the sequel to the action-hero-rich actioner that Simon West is directing for Millennium Films. The movie already stars Sylvester Stallone, Jason Statham, Dolph Lundgren, Mickey Rourke, Terry Crews and Jet Li, as well as Chuck Norris and Jean-Claude Van Damme — with expanded roles for Arnold Schwarzenegger and Bruce Willis thrown in — and filming is set to begin in October. The original movie made $274 million worldwide. Hemsworth recently wrapped shooting on Lionsgate’s The Hunger Games.
