Lionsgate has released a new behind-the-scenes featurette for The Expendables 2.  The new film has Barney Ross (Sylvester Stallone) and his gang of mercenaries out for revenge, and also having to deal with a baddie (Jean-Claude Van Damme) who wants some weapons-grade plutonium.  This featurette isn't going to change anyone's anticipation for the flick one way or the other, but I do like the emphasis on practical effects and trying to offer a break from CGI-heavy action (although you will also notice green screens in this featurette).

Hit the jump to check out the featurette.  The film also stars Jason Statham, Yu Nan, Jet Li, Dolph Lundgren, Chuck Norris, Terry Crews, Randy Couture, Liam Hemsworth, Bruce Willis, and Arnold SchwarzeneggerThe Expendables 2 opens on August 17th.

Here's the official synopsis for The Expendables 2:

The Expendables are back and this time it's personal... Barney Ross (Sylvester Stallone), Lee Christmas (Jason Statham), Yin Yang (Jet Li), Gunnar Jensen (Dolph Lundgren),Toll Road (Randy Couture) and Hale Caesar (Terry Crews) -- with newest members Billy the Kid (Liam Hemsworth) and Maggie (Yu Nan) aboard -- are reunited when Mr. Church (Bruce Willis) enlists the Expendables to take on a seemingly simple job. The task looks like an easy paycheck for Barney and his band of old-school mercenaries. But when things go wrong and one of their own is viciously killed, the Expendables are compelled to seek revenge in hostile territory where the odds are stacked against them. Hell-bent on payback, the crew cuts a swath of destruction through opposing forces, wreaking havoc and shutting down an unexpected threat in the nick of time - six pounds of weapons-grade plutonium; enough to change the balance of power in the world. But that's nothing compared to the justice they serve against the villainous adversary who savagely murdered their brother. That is done the Expendables way....
