True, but Iron Man is a guy in a suit of armour that does everything for him - which he doesn't even have to wear in the movies now. Tony Stark is not supposed to be honed to physical perfection and a king of all forms of combat, ala Batman. He can just fire missiles at people. In addition, Downey doesn't even really wear the suit in the movies unless his face needs to be shown.
I was actually talking about RDJ being credible at his age. RDJ being in a young stark movie isn't credible for example. But the character is infused by the age, same as this new batman angle.
As for if the actor can pull of the physically grueling work. This isn't some live action florida boat show. Ignoring that the actor in question is physically fit(and avid sport player) and not in his 70's. Ignoring that much of this masked work can be handled by a stuntman(ala TDKT and hopkins in the zorro outfit), and ignoring snyders all out love for cgi replacement. Ignoring all that, filming a action scenes on a movie set isn't as demanding as one might think. It's not like trying out for an nfl draft.
Just for reference. Daniel Craig was in Casino Royale(playing a young bond mind you) at the age of 38. He recently did skyfall at the age of 45 I believe. Safe to say his work in those and the physique requirements are as demanding as any of these comic books. Then we have jason statham who I believe is about 46 right now...Dwayne Johnson 42..etc Affleck is 41 and filming now, with the follow up about a year after that.
These are what needs to be in the conversation, not the fact that rdj is in a digital suit and a green room.
Starting to forget why we are talking about this particular thing here though.
But it's easier with the X-Men films, as all audiences have to do is watch three films in the order they came out, with years inbetween each one. To follow it, all you need to do is watch the movies as they are released.
With a TV show,a prequel and an older Batman in the JLA movies all running consecutively...you're just asking for viewers to get confused.
I didn't cite xmen as an example of them doing what I'm talking about. Clearly xmen doesn't run all continuities at the same time, the films are spread out. I referenced xmen in an attempt to highlight an example of 3 different points in the same continuity.
Could they run them all at the same time? Maybe, but it's alot easier to do that than to do ASM and Spderman at the same time. That's my point.
Running future bats in the films and prequel to gotham on tv makes alot of sense imo.
