Now Paramount has announced that they are bringing back director Jon M. Chu for the third installment of the franchise. It's not yet clear who from "Retaliation" will be joining him, although Dwayne "The Rock" Johnson is a good bet. He told CNN last March that "Retaliation" was a "massive opportunity." He added, "I enjoy being in franchises because they make a lot of people happy around the world... That's a lot of smiles, and that's a cool thing." (Also, money.)
At the moment, the third "G.I. Joe" movie doesn't have an official title or a writer attached, so there's no telling what direction this actioner will go in. We can expect to hear more very soon, as one could speculate that "Joe" is on the fast track for next summer.
