Lionsgate has released a roll call/teaser trailer for The Expendables 3.  While this footage bills this outing as the "last" time, I have trouble believing that.  But that's a concern for the future.  Right now, this teaser provides the first footage from the movie (explosions!), and mostly provides a roll call of the many, many tough guys (and gal) populating the movie.  But that's fine since The Expendables movies are more about a stacked cast than anything else.

Hit the jump to check out the The Expendables 3 teaser trailer, and click here to see some of the character posters/glamour shots.  The film stars (deep breath) Sylvester Stallone, Mel Gibson, Harrison Ford, Wesley Snipes, Arnold Schwarzenegger, Kelsey Grammer, Antonio Banderas, Jason Statham, Jet Li, Dolph Lundgren, Randy Couture, Terry Crews, Kellan Lutz, Ronda Rousey, Victor Ortiz, and Glen Powell.  The Expendables 3 opens August 15th.
