Liam Hemsworth is the latest name to join the cast of The Expendables 2, Variety reports. There's no word on his role quite yet, but he marks a surprisingly youthful addition to the cast of seasoned action stars, already slated to include Sylvester Stallone, Bruce Willis, Arnold Schwarzenegger, Chuck Norris and Jean-Claude Van Damme.

Co-written and directed by Stallone, the original Expendables also starred Jason Statham, Jet Li, Dolph Lundgren, Eric Roberts, Randy Couture, Steve Austin, David Zayas, Giselle Itie, Charisma Carpenter, Gary Daniels, Terry Crews and Mickey Rourke. Who among those that may be returning for the second film (this time directed by Simon West) has yet to be confirmed, though newcomers Nicolas Cage and John Travolta are also said to be in talks.

Hemsworth is set to appear early next year in The Hunger Games and will play a leading role in the upcoming AWOL as well.

The Expendables 2 will begin filming next month in Bulgaria and is planning an August 17, 2012 release.
