With director Jon M. Chu‘s G.I. Joe: Retaliation opening June 29, Paramount and Hasbro are starting to amp up the promotion of the movie by releasing a great new trailer and by having some of the cast (Dwayne Johnson, Adrianne Palicki and D.J. Cotrona) talk about the film at CinemaCon in Las Vegas. Prior to doing the interviews, I got to watch an impressive five minute sizzle reel and the new trailer with a group of reporters. If you were disappointed with the first G.I. Joe movie, the sequel looks to be a big improvement, as it’s going for a more real world approach while still trying to be a fun action movie. Also, with the majority of the Joe’s possibly getting killed in the first ten minutes (which is why it’s called Retaliation), the sequel could almost be considered a reboot. The sequel also stars Bruce Willis, Channning Tatum, Byung-hun Lee, Ray Park, RZA, Ray Stevenson, Joseph Mazzello, Elodie Yung, and Walton Goggins. Hit the jump for more.
