Marvel fans can breathe a sigh of relief. Everyone's favorite billionaire superhero -- Iron Man -- will return for "The Avengers 2," and beyond. While the status of a fourth solo "Iron Man" outing is still up in the air, Robert Downey, Jr. has inked a deal for two more installments in the "Avengers" series. Now all Marvel and director Joss Whedon need is for the rest of the super-cast to finish negotiations to return in the Summer 2015 blockbuster.
