Marvel films are notorious for their cameos. They were a major part of plotting their biggest film to date—The Avengers. Speaking of the superhero team, don't expect them to come to Tony Stark's rescue. In Iron Man 3 (aside from War Machine), he won't have any extra support.
The Avengers experience had a major effect on Stark. According to Marvel chief Kevin Feige, the hero's world has been rocked. He tells Empire Magazine that he's a changed man.
"By the end of Avengers, when a portal is opened up in Manhattan and he's met Thor and The Hulk and the Chitauri are coming down on him, he realises that he doesn't know everything; we think that has had an effect on his psyche, and then his world is blown out from underneath him."
Don't count on Stark's superhero peers to bail him out. They've got their own problems to deal with. Iron Man 3 will be light on surprise appearances.
"Iron Man 3 doesn't feature any of the other Avengers, or Nick Fury showing up, or any of those world-blending conceits that the Phase One films had," Feige reveals. "You have to keep in mind that Iron Man 3 had been in the works for almost a year, year and a half before The Avengers was released. We're sticking to the vision for these films, and showing once again that these characters are just as interesting alone as they are together."
Since this is the "final" installment of the Iron Man series, perhaps it doesn't need all the bells and whistles? At this point, Robert Downey Jr. and his supporting cast are more than capable of carrying the film.
Iron Man 3 opens in theaters May 3.
