While it's not uncommon for studios to shuffle opening dates, it is rare for such a big-budget movie to get the bump so close to its release.
Paramount executives told the Reporter the move was made so the studio would have time to convert "G.I. Joe: Retaliation" into a digital 3-D version.
Action films often get most of their revenue from 3-D showings, which cost a few dollars more per ticket and can boost a movie's prospects to make its money back.
Paramount did not immediately return calls from The Associated Press.
