Re: If J.A.R.V.I.S ever took a physical form, what would it look like?
Well the Jarvis idea is largely excusing the use of Bettany since it would look out of place if he shared the same voice, but no other connection. Though if they use Ultron then I'd maybe propose that Ultron should use the Jarvis programme as a basis since they can't use Wonder Man (I don't picture them including Wonder Man before Vision and a lot of other candidates).
Lady Luck is smiling at me. She knows something I don't.
