Robert Downey Jr. is already the epitome of being an Iron Man, the character, the looks and the suit fits him well, especially that this role made him to the major movie stardom. But if there is someone who will make him change his mind about doing the 4th franchise of Iron Man, it would be no other than his best bud, director Mel Gibson. Luckily, the actor-turned-director shows interest in doing "something different" when he was asked about making this project for Marvel Studios.

Robert Downey Jr.'s statement left fans to wonder who will be the next Tony Stark if Mel Gibson declines to direct Iron Man 4. On Christian Today, Downey's saying that he would do Iron Man 4 "if pal Mel Gibson will helm it" has developed a threat of shortage for the Tony Stark role. But since Mel Gibson has given a hint of interest in the Marvel franchise, Robert Downey Jr. may eventually get what he wants for Tony Stark's possible last show.

On the other side of the coin, Mel Gibson can do the lead role, given his award winning acting skills from "Braveheart" and more, but has already declined the superhero role based from reports of GameNGuide. Mel Gibson said on possibly directing Iron Man 4 that "It might be fun" by "figuring out a way to be different with that", thus the "Blood Father" actor/director will do a bit of a twist here and there for the single-themed film. Genre-wise, Gibson is not really boxed in a single theme which would be helpful should he take on the film as the MCU usually likes to feature a variety of genres.

Getting Mel Gibson in Iron Man 4 is not only for money sake or fame, but it is just one of the many samples of Robert Downey Jr.'s friendship with Mel Gibson. It has been known how Gibson has helped Downey Jr. during the latter's moments in drug and alcoholic dependency. Same is true for the Sherlock Holmes actor when he publicly pleaded to forgive Mel Gibson when he was entangled with scandals.
