Marvel made the announcement on their website Thursday.
While Downey Jr. has agreed to more “Avengers” action, the new deal does not mention a fourth “Iron Man” film.

Joss Whedon, director of “The Avengers,” recently said in an interview that he had no intention of making a sequel to the without the Oscar-nominated actor.
“He is Iron Man,” Whedon said. “He is Iron Man in the way that Sean Connery was James Bond.”
