Of course he's a great actor who can play other characters, and I'm sure his he'll give a great performance playing a very different character from Tony Stark, but I find it very hard to believe that they won't leave him recognizable as Tony Stark.
And you're not unreasonable to think that. I just think it's worth considering all possibilities instead of just one, since you never know for certain until it happens. I also don't
want him to play a Stark variant, so I'm hoping they go a different route, and I'm suggesting reasons they conceivably might.
Yes, but if they just wanted a character actor with a recognize name and voice, there are plenty of other very popular choices they could have made.
But as I suggested already, the reasons why directors and producers cast actors are often about things the audience doesn't see but the filmmakers do -- not what an actor looks like or how they perform, but what they're like behind the scenes as coworkers and colleagues. Whether they're professional and reliable vs. flighty and inconsistent, whether they're good partners and team players vs. prima donnas or jerks to their co-stars and crew, etc. Those sorts of things are, if anything, even more important to filmmakers' hiring choices than the onscreen performance that the audience sees.
What I said before about Marvel's reason for bringing the Russo Brothers back may apply here too. If they're trying to regroup after some failed gambles, and if they're under a time crunch and can't afford delays, it's logical that they'd turn to collaborators they know and trust, people they have a long relationship with and can count on to do the work reliably without creating problems.
Yes, it could be that they want him back because he was Tony Stark. But what I'm trying to get across, what is sadly overlooked by a vast number of MCU fans, is that there is much, much more to Robert Downey Jr. than just Tony Stark. He is a brilliant, chameleonic, recently Oscar-winning character actor, and it's not out of the question that they simply want him because the role of Victor Von Doom demands a brilliant character actor.
I mean, for most of film history it's been normal for filmmakers to keep bringing back actors they knew and trusted to play different characters. Look how many different roles Bela Lugosi, Boris Karloff, Lon Chaney, Evelyn Ankers, Lionel Atwill, etc. played in the Universal Monsters films. Look how Joe Dante had a regular repertory company including the likes of Robert Picardo, Dick Miller, and William Schallert, or how Tim Burton cast Johnny Depp and Helena Bonham Carter in nearly everything. It's not about any one role, it's about the working relationship with the actor, the director's knowledge that a given actor is someone they can rely on to do a good job and to understand the director's goals and wishes. After all, playing different roles is an actor's job. So an actor's skill and professionalism matter more than who the character is.
I'm sure they're going to more with Doom than just make him a "subset" of Tony.
Which is exactly why making him a Stark variant seems like a terrible idea that would just get in the way of doing Doom justice as a character. I can't see the value of that. I
can see the value of letting a gifted character actor bury himself in a new role without reference to a previous one.
I'm thinking the opposite, that they're possibly shifting at least some of their variant ideas for Kang over to Doom. They've done a lot of work to develop the whole variant concept with Kang, I could see them salvage at least some of the those concepts to use for Doom too. Like I said before, the idea of variants has been a huge part of the Multiverse Saga so far, so it makes perfect sense that they'd make the big bad a variant of one of the 616 universe's biggest heroes.
Again, I concede that's possible. But I find it undesirable, because it doesn't do Doom justice to make him a pinch-hitter for another character's storyline. So I'm
hoping they plan to do something different. I'm not assuming they will, just looking for reasons to hope.
