No. More likely is it was just an artistic choice. The story is about us getting Hulked out, and our journey more than his.Anyways, I really miss "I think this time it's going to work!" I've heard rumors that the reason they gave it a new story was to reduce mentions of the character Bruce Banner to cut down on how much they had to pay Disney? Any truth to this (do they even have to pay Disney)?
And it's easier/cheaper to not hire an actor at all. Plus, now there's no disconnect between Ruffalo, or whoever plays him in the future, and the character in your mind.
But there's no way they pay Disney any less due to any changes. And if anything, this new update sees more Marvel characters added that weren't really mentioned in the original iteration, with General Ross and other various characters' names posted around the lab/government testing site.
