Marvel has shifted around the third phase of their cinematic universe by moving Edgar Wright's "Ant-Man" by a few months.
Originally slated for November 6th 2015, the superhero film is now locked into a late summer bow on July 31st 2015. That's two weeks after the "Man of Steel" sequel.
That said, the film has little to no competition in that release slot - one of the only quiet weeks in what's being called "The Biggest Summer Ever" for filmgoing.
The date change also gets it away from the obvious box office behemoth in November - the next James Bond film.
