it's not coming out until MARCH 2013 so the studio can do a CONSCIENTIOUS JOB with the 3D....

either this is shrewd marketing or the film is a hot mess because the 3D should have already been done for this...sounds suspect. But, if you're still going to see it..get those tickets MARCH 2013.

EXCLUSIVE: The sequel G.I. Joe: Retaliation was supposed to come out this summer on June 29th. But I’ve learned that Paramount is moving the movie nine months to March 29, 2013, to add 3D. “We’re going to do a conscientious 3D job because we’ve seen how it can better box office internationally,” one of the studio execs just told me. “Jim Cameron did all of Titanic‘s 3D in post – and look how well that movie turned out.” Paramount has had luck delaying films before: its decision to move Martin Scorsese’s Shutter Island gave the director his biggest box office hit ever. Also the execs say that the blockbuster performance of The Hunger Games shows that March can be a prime time of the year to release movies. Of course, Paramount had to talk its partners on GI Joe 2 into the extra nine months of carrying costs – MGM/Spyglass which has 25%, and David Ellison’s Skydance which has another 25%. The $125M-budgeted actioner stars Channing Tatum, Dwayne ‘The Rock’ Johnson, and Bruce Willis and is directed by John Chu.
