Well, in this case, they’re recasting because the actor died. So I can see wanting to stick to an actor close in age. Since they aren’t rebooting the MCU yet, it wouldn’t make sense for General Ross to go from William Hurt to Brad Pitt (although I think Pitt would make a great General Ross).
Well…that would certainly be the most high profile duplicate acting in the MCU, but not unprecedented. (honestly, I forgot he played Stane)
