It was always unclear why Captain America couldn't lift Mjolnir in Age of Ultron.
Was he not worthy at all? Unlikely; it's Captain America after all, worthiness goes with the character, his MCU version at least. Plus, Mjolnir did move. (Note that in the comics, Cap has wielded Mjolnir)
Was he not completely worthy yet? Possibly. After all, there is still ...
Out-of-universe - it's a name, rather than an acronym.
A mix of 'Ultroids' and 'tron'
In an interview with The Hollywood Reporter, Roy Thomas, who co-created Ultron, answered:
Where did the idea for Ultron come from?
I never considered myself very good at making up names. Some of the first creatures I made up fighting The Avengers were part of a ...
Because he was willing to sacrifice himself to protect others.
The reason why Cap managed to do so is already explained in Thor Trilogy. Thor was unproved of worthy in Thor when he committed a war which could lead to deaths of many. However, when he was willing to sacrifice himself for those who he loved by the end of the film, he proved himself worthy. ...
It's not an acronym.
Name "Ultron" actually came from the ancient times:
The inspiration behind the name "Ultron" actually came from the Roman
god of war Mars whose full name (in terms of the version chosen for
Ultron's inspiration, at least) is "Mars Ultor". The literal
translation of Mars Ultor is actually "Mars the Avenger", which
as TheLethalCarrot suggested, it was a tactical retreat keep Ultron alive. After he was born and the Avengers questions his allegiance, Vision explained how even Ultron's forms had to be destroyed
Vision: What will you do? [he looks at them all realizing they will destroy him] I don't want to kill Ultron. He's unique, and he's in pain. But that pain will ...
From my own previous answer:
Thanos decides to do it himself after (it is assumed) the events of Age of Ulton although it's not clear when this event actually takes place in the MCU timeline
We do know that Thanos had the Infinity Gauntlet constructed by Eitri at Nedavellir but it's possible that this actually took ...
Because Bruce Banner being Hulk is not a secret identity and nobody have to do any maths to prove it. He doesn't dress up as Spider-Man in hiding but he just transforms in front of everyone.
So Wanda knowing it doesn't look like a big thing and remember they have been trained by Hydra to be used against Avengers so they must have done basic homework.
Is Cap's last line, reference to the events of Civil War that will follow?
There's no reason to think so.
Cap doesn't turn dark during the events of Civil War, in fact he sticks to his exacting principles of honor and justice rather than submit to an authority in which he does not believe.
If anything, it's Tony who does the turning but that's a matter of ...
“How is Steve Rogers not worthy?” a fan asked. “Is he not? Are we sure?” Whedon responded, a hint of teasing in his voice. “Did he fail? Or did he stop?”
For those who don't know: Joss Whedon is the director for Age of Ultron. He stated that in 2015.
Like others have already said, Cap has been worthy. Also, I've seen people ask how he was able to use ...
This has been asked with screenwriter and director too and their answer from businessinsider
How does "Avengers: Infinity War" fit with "Age of Ultron"?
Asked about this at a press junket, screenwriters Stephen McFeely and Christopher Markus seemed unconcerned about this. "Not our movie," McFeely joked. "We've all sat there and went, 'What the hell is ...
He is worthy enough to do so, but decided not to out of humility.
Here's the official answer, from Joe and Anthony Russo:
Anthony replied: “In our heads, he was able to wield it. He didn’t know that until that moment in Ultron when he tried to pick it up. But Cap’s sense of character and humility and, out of deference to Thor’s ego, Cap, in that moment ...
Other than "Jarvis" and "Friday", there are at least THREE other named AIs and possibly several other unnamed ones.
Two of which are seen in Age of Ultron
These are JOCASTA & TADASHI as detailed in this earlier M&TV Q&A: What were the other A.I. chips and whom are they referring to?.
Note that there are at least TWO other chips seen but the ...
From the movie script:
Vision: What will you do? [he looks at them all realizing they will destroy him] I don't want to kill Ultron. He's unique, and he's in pain. But that pain will roll over the earth, so he must be destroyed. Every form he's built, every trace of his presence on the net, we have to act now. And not one of us can do it without the ...
As we know that being born rightaway, Vision was suffering through an identity/existential crisis, figuring out what he is, his purpose, reason for existence etc.
The conversation between him and the Avengers showed that he is on the good side, and the conclusion of the meeting was that 'Ultron must be destroyed'.
Destroying Ultron through the internet was ...
In the comics Thor said the enchantment that Odin put on Mjölnir allows "very few worthies" to lift it in "desperate hours". Given that Thanos was about to kill Thor and would have killed everyone and everything, I'm guessing that qualifies.
If you watch the scene, Captain America doesn't appear to be holding back and as Vision put it, it's very well ...
While he needed help to do it, he of course also created Vision and Ultron.
Veronica does not seem to be classed as a full AI by the MCU's Wiki, which describes it as a 'mobile service module deployed from a space satellite... stocked with automatic assembled parts of the Iron Man Armor: Mark XLIV for real time customization of the Hulkbuster armor and ...
