Avengers: Age of Ultron2015

[After the other Avengers have tried and failed to lift Mjölnir]

Tony:
The handle is imprinted, right? Like a security code. "Whoever is carrying Thor's fingerprints," I think, is the literal translation.

Thor:
Yes, well, that's a very interesting theory. However, I have a simpler one. [Easily lifts the hammer and flips it with one hand] You're all not worthy.

Ultron:
[Slowly] Worthy.

Ultron:
No, how could you be worthy? You're all killers.

Rogers:
Stark…

Tony:
JARVIS…

Ultron:
Sorry, I was asleep… Or… I was a dream.

Tony:
[Tapping his phone] Reboot Legionnaire OS, we got a buggy suit.

Ultron:
There was a terrible noise… And I was tangled in… in… strings… I had to kill the other guy. He was a good guy.

Rogers:
You killed someone?

Ultron:
Wouldn't have been my first call. But, down in the real world we're faced with ugly choices.

Thor:
Who sent you?

Ultron:
[Replaying Tony's voice] "I see a suit of armor around the world."

Banner:
Ultron!

Ultron:
In the flesh. Or, no, not yet. Not this…chrysalis. But I'm ready. I'm on mission.

Natasha:
What mission?

Ultron:
Peace in our time.
