THE FIRST MAJOR action-packed movie of the summer, G.I. Joe: Retaliation is the follow-up to 2009's G.I. Joe: The Rise of the Cobra (which made $54M in its opening weekend and shot Channing Tatum into the stratosphere for popularity, but was not a critical success to say the least). However, the new one has differentiated itself from the original movie by adding a slew of new actors to the mix, including Bruce Willis and Dwayne "The Rock" Johnson, both of whom, combined with Tatum, are a force to be reckoned with and a trio of bona-fide blockbuster-making action stars. G.I. Joe: Retaliation, much like another upcoming summer flick, Battleship, takes cues from the Hasbro school of film, i.e. turning childhood toys and games into major motion pictures (Transformers, anyone?). With not much competition on the weekend of June 29th (although Tatum is competing against himself here, with his other flick Magic Mike coming out the same day), we have a pretty good feeling that this one will score big.
