Lionsgate has released a new The Expendables 3 trailer and banner.  The follow-up finds Sylvester Stallone’s Barney Ross and his Expendables crew squaring off against Ross’ old partner Conrad Stonebanks, played by Mel Gibson.  This trailer is exactly what we've come to expect from an Expendables movie at this point.  You're either in or you're out, and there's no changing the formula, only the cast members.  This new trailer gives more attention to new additions such as Wesley Snipes, Antonio Banderas, Kelsey Grammer, and Gibson, but not too much since we also have to see lots of explosions and shooting lest we fear those elements may not be part of the film.  At this point, "Explosions" and "Shooting" should get their own character posters, top billing, and a chance to walk the red carpet.

Hit the jump to check out the new The Expendables 3 trailer.  The film opens August 15th, and also stars Harrison Ford,  Arnold Schwarzenegger, Jason Statham, Jet Li, Dolph Lundgren, Randy Couture, Terry Crews, Kellan Lutz, Ronda Rousey, Victor Ortiz, and Glen Powell.

Here's the official synopsis for The Expendables 3:

In THE EXPENDABLES 3, Barney (Stallone), Christmas (Statham) and the rest of the team come face-to-face with Conrad Stonebanks (Gibson), who years ago co-founded The Expendables with Barney. Stonebanks subsequently became a ruthless arms trader and someone who Barney was forced to kill… or so he thought. Stonebanks, who eluded death once before, now is making it his mission to end The Expendables — but Barney has other plans. Barney decides that he has to fight old blood with new blood, and brings in a new era of Expendables team members, recruiting individuals who are younger, faster and more tech-savvy. The latest mission becomes a clash of classic old-school style versus high-tech expertise in the Expendables’ most personal battle yet.
