But it helped when an acting coach told him to try to bring the character of Victor Frankenstein into the role.

How would Victor feel being trapped inside of Josh's small life?

This is exactly what Oscar needed to step into the character.

In this scene from the series, Josh and his wife, Lindsay, played by Carey Mulligan, are home after spending the day at the country club.

They get into an argument, which turns into a full-blown fight, with both of them saying the worst things a married couple could say to each other.

It's intense.

Oscar Isaac is a Golden Globe winner who has moved between indie films and global franchises from Shakespeare to Star Wars.

His films and TV work include Inside Llewyn Davis, Dune, Card Counter, Scenes from a Marriage, and most recently, Frankenstein.

Oscar Isaac, welcome back to Fresh Air.

We're going to get to that intense fight in just a second.

But, you know, first I want to talk to you about this thing this acting coach told you to bring Victor into the room.

Why was that the key to unlock this character, Josh?

You describe Josh as living in a small life, but he manages this world with a lot of old money and privilege.

Can you explain that a bit more?

Yeah.

At the end of the day, he is the help, for lack of a better term.

Thinking about this character, Josh and Beef, he doesn't belong there, really.

But his way of giving back is through service.

And then there is this fight where we just see another side of him.

So he's charming to all of the people who are part of the club.
