You'll be whistling the "Colonel Bogey March" after watching this amazing teaser trailer, which highlights the massive cast of The Expendables 3.

Lionsgate has unveiled a new clip for Sylvester Stallone's wildly popular action-adventure franchise, which has eight months to go before its August 14, 2014 release date.

After finishing shooting this past summer, the third installment finds Barney (Sylvester Stallone), Christmas (Jason Statham) and the rest of the team coming face-to-face with Conrad Stonebanks. Played Mel Gibson, Stonebanks co-founded The Expendables with Barney.

He became a ruthless arms trader and Barney was forced to kill... or so he thought. Now, after eluding the clutches of death, Conrad Stonebanks has made it his mission to end The Expendables.

Watch the teaser trailer below:

Yes, you saw that correctly... this installment finds Harrison Ford, Wesley Snipes, Antonio Banderas, Ronda Rousey, Victor Ortiz, Glen Powell and Kelsey Grammar enlisting their talents. Returning to the project are Randy Couture, Dolph Lundgren, Jet Li, Kellan Lutz, Terry Crews, and Arnold Schwarzenegger.
