The cross promotion will only grow as time goes on and the latest instance of it comes from the upcoming release of Iron Man 3, which hits on September 24th in advance of the November 8th release of Thor: The Dark World. The release will have a special featurette on that movie, which a clip of which has been released that you can see below, that has the cast and creative team talking about the direction of the film and the characters that more firmly cements it off Earth, which is definitely a needed element for this particular character after two Earth-centric films.
Plot concept: Thor: The Dark World continues the big-screen adventures of Thor, the Mighty Avenger, as he battles to save Earth and all the Nine Realms from a shadowy enemy that predates the universe itself. In the aftermath of Marvel’s “Thor” and “Marvel’s The Avengers,” Thor fights to restore order across the cosmos…but an ancient race led by the vengeful Malekith returns to plunge the universe back into darkness. Faced with an enemy that even Odin and Asgard cannot withstand, Thor must embark on his most perilous and personal journey yet, one that will reunite him with Jane Foster and force him to sacrifice everything to save us all.
