Lionsgate has released a new TV spot for their upcoming “mercenaries on a mission” action flick, The Expendables, which was co-written and directed by the film’s star, Sylvester Stallone.

Stallone plays Barney “The Schizo” Ross, the fearless head of an elite group of warriors-for-hire whose ranks include Lee Christmas (Jason Statham), Yin Yang (Jet Li), Hale Caesar (Terry Crews), Toll Road (Randy Couture) and Gunnar Jensen (Dolph Lundgren).  Despite their silly names, these men are the best at what they do – namely, clobbering the bad guys and blowing stuff up.

The crew’s latest mission has them infiltrating a South American country as to overthrow its dictator, the brutal General Gaza (David Zayas).  However, all is not what The Expendables were led to believe and the team of tough guys find themselves doing battle against an evil ex-CIA operative (Eric Roberts) and his loyal muscle, the aptly-named Paine (Steve Austin).

If this plot synopsis and the most recent teaser trailer for The Expendables make the film seem a bit on the heavy side, the latest TV spot strikes more of the fun tone you’d expect from an explosion-filled summer movie.  The mix of Kiss’ “Rock & Roll All Nite” and shots of Hollywood’s bad boys doing what they do best definitely paints a more spirited picture of the movie.

You can check out the new TV spot below:

The Expendables will be the third “team of soldiers on a mission” film to hit theaters this year, after the spring box office dud that was The Losers and this weekend’s The A-Team.  So far the promos for the Stallone-directed feature have been more serious in tone than those other two pics, but not so much that they make The Expendables look like a chore as opposed to the mindless bit of summer fun that everyone expects it to be.

What do you think?  Does The Expendables look like a good time?  Sound off in the comments section below.

The Expendables hits theaters in the U.S. on August 13th, 2010.
