"And I'm Joe Russo."

"And we are the directors of 'Avengers: Endgame.'

This is a scene that happens relatively early in the film

where we are catching back up with our characters after

a five-year time elapse once they have definitively lost

to Thanos--

after he's eradicated half of all life.

Everyone's taking that occurrence badly, of course,

but some are taking it worse than others.

Thor blames himself for the loss in many ways.

And he's basically masking it.

He's hiding in things like alcohol, and food,

and video games, and TV.

And he's cloistered himself in this cabin here,

and he's very much hiding from the pain that he can't face."

"Boys!

Oh, my God!

Oh, my God, so good to see you!

Come here, cuddly little rascal.

[GRUNTS]

"Yeah, no, I'm good.

I'm good."

"I think why this is one of our favorite scenes

in the movie is this is an exceptional performance

from Hemsworth.

One of the hardest tones to play

as an actor is to play both pathos and humor,

and he does it with such a delicate touch in this scene.

You really have to commit to stakes,

you have to commit to emotional truth

in order for the performance not to get ridiculous.

That's why it's so difficult, because it can go

absurd on you very quickly.

And he does it.

He grounds it.

And this is right around the section

where he starts to ground the performance."

"And he's grounding it, of course, surrounded

by a bunch of CG actors, which is doubly hard to pull off."

"And while wearing a 30-pound body suit."

"Yeah.

And Joe and I, as filmmakers, we love to play with tone.

We like very complicated tones.

And this scene, I think, is really juicy for us

because it starts from such a silly, absurd, frivolous

place in terms of how Thor is hiding, what kind of behavior

he's adopted to get away from the pain."

"So what's up?

You're just here for a hang or what?"

"We need your help.

There might be a chance we could fix everything."

"Well, like the cable?

Because that's been driving me bananas for weeks."

"Like Thanos."

"And this is a moment right here where,

in a single moment, when Hulk says 'Thanos,' you see Chris

Hemsworth reveals to us the pain that he's been masking."

"He's a tragically haunted man.

And the tone shifts there very, very delicately."

[SOMBER MUSIC]

"Don't say that name."

"Even Korg shifts tone and becomes

part of the conversation in this moment."

"The scene has a wonderful shape to it in the sense

that we start from a place of lightness.

It moves to a place of real darkness.

And then at the end, there's some kind

of bizarre reconciliation of the two."

"Why would I be?

Why would I be scared of that guy?

I'm the one who killed that guy, remember?

Anyone else here killed that guy?"

"To get a peek into the window of how we would shoot a scene

like this.

So we didn't have Taika on set that day,

so there's a motion capture actor playing Korg.

We voiced Taika later.

Ruffalo's on set wearing, basically,

the equivalent of pajamas which are a motion

capture suit.

And we have him on a platform so he can move around

at the height he needs to move around at so he can have

eye contact with Hemsworth.

And when Hulk touches Hemsworth,

we just replaced that with a Hulk hand

instead of Ruffalo's hand.

And then we have--

James Gunn's brother plays Rocket on set.

He's crawling around on the ground on his knees

so that he can also be at the same height as Rocket.

So it's very complicated to pull off a scene like this,

and then to add in these difficulty-in-tone complexity

of performance for Hemsworth, and this

is about as a high degree of difficulty

as it gets for an actor."

"You also notice the room--

for as funny as this scene is, the room

is very moody and dark.

I think that really speaks to the fact

that there's a duality going on in this scene,

and that ultimately, the story lies in Thor's pain.

And that that's really what we're

moving here through on a story level here,

and what this character is trying to push through.

You'll notice that the screen is blurred,

and that's because of some obscure rights issue.

'Fortnite' is actually playing on that screen,

but for some reason in this clip, we can't play it."
