But Whedon, again, played against the obvious: “I was like, ‘With my dying breath…’ I don’t have to say that a lot, but sometimes I’ll turn to [Marvel head honcho] Kevin [Feige] and say, ‘With my dying breath…’”.

And he made it: “[…] it was in the script exactly as you see it. ‘He draws breath to say the next word. Blackout.’ So to know that we landed exactly where I wanted to go, however many stumbles along the way, was extremely gratifying”.

However, a bit of frustration always makes its way through. ‘Cause after locking the film, Whedon was offered the possibility to slot Captain Marvel and Spider-Man in.

“I said, ‘It would be great if we could add a few more. If we could have a Captain Marvel there…’ And they talked about it. And Spider-Man, because Sony had approached us during the first movie about integration”.

And he adds: “so I would have put both of them in, but neither of the deals were made, and then it’s, ‘We’re making a Captain Marvel movie, and we’ve got Spider-Man as a property!’ I was like, ‘I’ve already locked my film, you fucks. Thanks for nothing!’”.

That’s, at least in part, why Spider-Man and Captain Marvel didn’t make it to Age of Ultron!

5. On The Vision wielding Mjolnir

The moment when The Vision lifts Thor’s hammer was listed by me as one of the most shocking moments in Age of Ultron. How did Whedon come up with that?

This notion was not included in the original script. In fact, it “came from a ‘Do you know what would be cool?’ moment. It’s the cheer moment of the film”.

And there were plenty of previous sequences to encourage a moment like that. In Whedon’s words:

“And what’s great is that […] we’d unknowingly set it up, just by having that [‘Who is worthy enough to Mjolnir?’] sequence, then with Quicksilver as well, trying to grab it and it throws him off. Both of those things were in the script before I came up with the idea of [the Vision lifting Mjolnir]”.
