yep, he "could have" lifted it in Ultron.. just didn't do it to disgrace and belittle Thor... because he was kind at heart, and knew it would not be right.
Vision could lift it, only because he was pure of heart, and not a "living thing", he was an android...
no spoilers... dammit...
when Daddy Oden banished him to earth, Thor couldn't lift the hammer even.. going back thru time...
comic geek I am...
oh, by the way... in the actual comics, Cap, first lifted the hammer back 31 years ago.... just saying... and a few times since that point.
I'm still getting my mind around how the hammer "comes back" after it was destroyed by his sister originally, then replaced with another one, and that one got destroyed also... prior to the "finger snap"...
tooooooo muchhhhh brain overload....
saying I have not seen the film yet, I'm curious of what cameo appearance Stan Lee had in this last film, I see he did complete his footage before he died last fall... R.I.P. Stan... you will be missed... Nuff Said...
