Wondering why Ant Man isn’t the Creator of Ultron? After all we all know that Hank Pym created Ultron in the comics, yet in the Marvelverse chain of movies it seems that Ultron will be created by Tony Stark.
Well it appears that Joss Whedon has some pretty good reasons and part of it is simply common courtesy. In April 2014, Empire Magazine interviewed Joss Whedon and at that point he explained his reasoning. It’s only recently that portion of the interview has come to light.
“Of all the heat I’ve ever taken, not having Hank Pym was one of the bigger things,” says Whedon. “But the fact of the matter was, Edgar [Wright] had him first and by virtue of what Edgar was doing, there was no way for me to use him in this. I also thought it was a bridge too far. Ultron needs to be the brainchild of the Avengers, and in the world of the Avengers and the MCU, Tony Stark is that guy. Banner has elements of that guy – we don’t really think of him as being as irresponsible as Tony Stark, but the motherf**ker tested gamma radiation on himself, with really terrible, way-worse-than-Tony-Stark results.”
“It didn’t make sense to introduce a third scientist, a third sciencetician, to do that,” Whedon continues. “It was hard for me, because I grew up on the comics, to dump that, but at the end of the day, it’s a more interesting relationship between Tony and Ultron if Tony was once like, ‘You know what would be a really great idea?’ They’re doing what they always do – which is jump in headfirst, and then go, ‘Sorry, world!’ But you have to make it their responsibility without just making it their fault.”
In the interview with Empire, Whedon told the world how he made Ultron a little less uber-powerful and give him more of a personality, “With Ultron, we have to make him slightly less omnipotent because he’d win. Bottom line. Also, having weaknesses and needs and foibles and alliances and actually caring what people think of him, all these things, are what make him a character and not just a tidal wave. A movie about a tidal wave can be great, but it’s different than a conflict between one side and the other.
In this case, I think taking Ultron away from his roots and creating new ones makes sense. We’ve already seen that Tony’s creations seem to have a mind of their own: just look at the robotic arm “Dum-E” and his personal assistant Jarvis. He programs stuff with personality in it. We don’t yet know what the cinematic version of Hank Pym will be like.
