'Iron Man 3' to be sequel to four other movies

Director Jon Favreau has revealed that Iron Man 3 will also be a sequel to four different movies - Thor, Hulk, Captain America and The Avengers.

Favreau, who directed Iron Man and Iron Man 2, spoke to MTV News about the future of the superhero franchise.

"In theory, Iron Man 3 is going to be a sequel or continuation of Thor, Hulk, Captain America and Avengers," Favreau said. "This whole world... I have no idea what it is. I don't think they do either, from conversations I've had with those guys."

Favreau also stated that he has no way of knowing what Iron Man 3 will be about, given that its plot will depend on the final versions of the four other films.

"Honestly, right now Captain America and Thor are their big priorities, and you learn things by shooting and making movies," Favreau declared. "The script is one thing, but when you actually see what you land on at the editing room - especially with Marvel where they film, cut, film some more and shape the film - you really learn as you go."

Iron Man 3 is scheduled to open on May 13, 2013.
