Warning: This article contains spoilers about Wednesday’s season 1 finale of Marvel’sWhat If…?.

And with that final reveal,What If…?concluded its first wild season.

AC BRADLEY:That was the Captain Carter moment, right Bryan?

WHAT IF…?

Marvel Studios

BRYAN ANDREWS:Yeah.

BRADLEY:[Laughs] When you write the script, you don’t write credits into it.

And we love Captain Carter and we feel like her story, it keeps going.

WHAT IF…?

Marvel Studios

There’s places for her to go, there’s still things for her to do.

As The Watcher says, “The world is not done with you yet.”

Let’s let them just be the episodes."

So it was organic, it just came up naturally.

What does that post-credits scene mean?

ANDREWS:[Laughs] We’ll see?

BRADLEY:The Watcher has his favorites.

I think we’ve seen that in the finale.

And he has a soft spot for Peggy Carter, especially Captain Carter.

So hopefully he’ll be popping into her world in season 2.

ANDREWS:That’s all we’ll say.

BRADLEY:That’s all we can legally say.

Can you tease whether or not that it actually is Skinny Steve in there and not someone else?

ANDREWS:What if?

[Laughs] What if?

We’ll have to see.

That’s a pretty good way to ask.

BRADLEY:[Laughs] Basically we’re asking Twitter to ask for us.

Why did you decide on making Ultron the final big bad of the season?

So we wanted to give him his due and show the actual pure terror of this horrific A.I.

that was created from a place of altruism and arrogance and see what he would actually do if unleashed.

ANDREWS:It was awesome.

I think there’s something really awesome about that, because they could be us.

BRADLEY:First of all, I love Ross Marquand.

He’s the nicest guy.

He is such a sweetheart.

ANDREWS:It just seemed to make sense.

Because inAge of Ultron, they get some version of Jarvis A.I.

into Vision so it makes sense that it’s that A.I.

with that voice that comes out of that body.

But the body can be whatever voice it wants because it’s this amazing thing of tech.

So if a pure Ultron A.I.

gets in there, there’s no reason why it would sound like Jarvis.

It’s Ultron injecting himself into this shell, so it’s his personality.

He could probably choose to sound any way he wants.

It’s an extra layer of unsettledness and tension.

Did you attempt to get James Spader to voice the character?

ANDREWS:I was under the impression that we tried to reach out to everybody.

And just some people maybe could or couldn’t for whatever reason.

BRADLEY:The casting of the Marvel actors really was a pay grade above us.

[Executive producer] Lou [D’Esposito] kind of spearheaded the whole operation.

That episode featured Tony and Gamora.

It was a lighter episode!

We didn’t murder Tony horrifically in this one, I promise!

[Laughs] But I’m getting hate mail.

ANDREWS:It’s a great episode; it’s funny.

But it’s coming I was seeing some shots on it just the other day so it’s coming.

It will be there for our second season.

Will we see him step into stories more in season 2?

Will there be ramifications for that decision?

ANDREWS:We’ll have to wait and see.

BRADLEY:I love The Watcher because he’s always a dramatic b—.

[Laughs] “I will not interfere.

I can’t possibly.

Okay, let me do this.”

You previously said all the season 2 episode scripts are written.

How far into production are you on season 2?

ANDREWS:They’re all in different stages of production.

The run times on all theWhat If…?episodes were significantly shorter than the other Marvel Disney+ shows.

BRADLEY:It was a mixture.

We designed the episodes to be between 25 and 30 minutes.

But I think it actually made the show tighter and swifter.

Special shout out has to go to our amazing editors Joel and Graham Fisher.

So we owe them a thank you.

ANDREWS:They really do great work.

They’re knee-deep in it right now; they’re working on some stuff right now.

I’ve got to meet with those guys later actually.

All ofWhat If…?season 1 is now streaming on Disney+.
