Iron Man is by far the most notable and most successful superheroes of Marvel Studios' Avengers ensemble. What's best is that his box office success shows it, as [Iron Man 3](movie:24391) is the sixth biggest box office film in history. Yet still, ten years ago, nobody knew who Iron Man was, or what kind of film they were in for.
Fans have spoken up about their love for the casting of Robert Downey Jr., whose fame since the first film has inspired people to be able to recognize him by his initials RDJ, and clearly stated that Iron Man wouldn't be Iron Man without Robert.
Recently, while talking to radio station 100.3 Jack FM, director Jon Favreau revealed he had to fight to get RDJ cast. Marvel Studios never originally wanted to cast Robert Downey Jr. as the part due to his boozing, drugged-out past. He was seen as far too big a risk to hang a franchise on. But Favreau suggested that his past would make him more valuable to the part, since the comic book Tony actually was a recovering alcoholic himself.
Everybody knew he was talented… Certainly by studying the Iron Man role and developing that script I realized that the character seemed to line-up with Robert in all the good and bad ways. And the story of Iron Man was really the story of Robert’s career.
Obviously, they made the right decision. Could you imagine if they had cast anyone else?
