So, as The Vision in the MCU, Paul Bettany has been thoroughly motion captured. Any other issues aside, his likeness could be used indefinitely, in a wide range of capacities. Meanwhile, there’s been talk that Wonder Man, another Marvel superhero, will eventually by introduced as played by Nathan Fillion.
In the comic plots, Vision possessed some portion of Wonder Man’s consciousness.
So, what if we were to eventually get a CGI rendering of Paul Bettany, but motion-controlled based on a performance by Nathan Fillion? Which performer would ‘own’ what part of that performance and how would it potentially impact our own impressions of those two actors and the characters they were portraying as independent/inter-related? How would the performers end up relating to one another? Would Fillion be playing Bettany just by looking like him, even if he were playing as Wonder Man?
