But there is one thing that many people wonder why Tony Stark was not allowed to say any lines before he died? With my big role, I should have had many stories as well as the last words. And the answer here is that it seems, actor Robert Downey Jr. himself. who made this decision. Once transformed into these roles for more than a century, certainly Robert Downey Jr. knew too well what he wanted to do when he cut a lot of Iron-Man’s lines in his character’s dying moments. And he did it for his own reason.
