We spotted this promo poster for The Expendables 2 tonight which lists the full cast for the sequel, including Sylvester Stallone, Jason Statham, Jet Li, Dolph Lundgren, Chuck Norris, Randy Couture, Terry Crews, Liam Hemsworth, Jean-Claude Van Damme, Bruce Willis and Arnold Schwarzenegger.
The skull poster design is identical as what was used for the first film, though this is just promo art and most definitely not an official poster for the film. The poster for the first film can be viewed here.
The Simon West-directed follow-up is currently filming for an August 17, 2012 release.
