'G.I. Joe: Retaliation' Trailer: The World Ain't Gonna Save Itself

The other day, the world got a first glimpse at the upcoming “G.I. Joe” sequel, “Retaliation.” With the official trailer now out, we can now see why it's called that – and just how action-packed it will be.

Starring Dwayne “The Rock” Johnson, Channing Tatum, Adrianne Palicki, Ray Park, RZA, Joseph Mazzello and Elodie Yung, the film also gets a spectacular cameo from none other than Bruce Willis.

As we also noted the other day, only The Rock and Bruce could get away with such cheesy lines like “The world ain't gonna save itself” and “My cholesterol is a little high” when asked if he's OK after a direct confrontation.

And yes, ninjas can do the most amazing things. 

“Retaliation” tells the story of the elite G.I Joe group, set up in a political game played on an international scale. A few survive a planned attack – and set out to clear their name.

Directed by Jon M. Chu, the film will be out in theaters on June 29, 2012. Check out the trailer above.
