They will have to make this decision one day, because this franchise has real legs and is very original - synthesizing the superhero movie with the James Bond formula, with a hint of Tom Clancy.
Who's a young up and comer right now, with the same kind of charisma? Hmmm...
You know, when they were casting for the first movie, I really thought they would look at Colin Farrell. He's still only in his mid 30's, and has no franchise of his own...

I think that's true. I don't think they would even be able to go the over the top, witty, mouthy stark route after RDJ because he owns that interpretation hands down. I think they need to go like the charming man of mystery type route if they started a new franchise of movies. Something like the Great Gatsby with armor, something with a little bit more of a serious tone.
Of course; he was even attached to the project around 2000. But he's 50 years old now, it's water under the bridge. Who is the best guy to take over in a few years time, that is the question.

God no! He's just a boring actor and aside from playing characters that are in some way or other inadequate, he doesn't really do anything well. His Justin Hammer was one of the many "bum notes" of IM2.
He MADE Iron Man the huge hit that it was. And I honestly believe The Avengers needs to credit much of it's success to him too.
But then I suppose you could see it as all the success really being down to Marvel studios casting the right guy (I initially thought he was an odd choice). As well as doing a Fab job in picking the right Directors - Joss Whedon.
