Marvel Studios and parent company Disney have yet to release The Avengers, but they're already hard at work on "phase two" of the Marvel Cinematic Universe, starting with Iron Man 3. That movie was set to start shooting at the end of May, after The Avengers had opened, but Comicbook.com reports the date's been moved up and filming could start as early as the end of April or the first week of May in Wilmington, North Carolina.
Marvel would not officially confirm the production change. It's likely that the studio will want Robert Downey Jr. to do press for The Avengers through April and, possibly, through The Avengers' opening date of May 4th. However, production could begin without Downey. "It is not April for sure," another Marvel source later told the site. Whether it shoots in early or late May, Iron Man 3 is set for a May 3, 2013 release date. more about Cap 2, S.H.I.E.L.D., and Doctor Strange >>
