I just don't understand this. Is this their way of having RDJ playing DOOM for 2 movies, and then they get him to come back as IRON MAN?
Because of what happened with Majors they decided to go with Doom as the new villain.
Disney shareholders were worried about The Avenger franchise and wanted RDJ back.
RDJ only wants to come back if he's being given new material and a lotta cash.
Disney need RDJ to at least look familiar to the casual viewer.
Dr Doom and Iron Man already overlap.
So they make him Doom.
