I wasnt really interested in doing anything that was campy.

I was interested in something a little deeper and a little bit more emotional and painful.

Part of that idea is born out of a conversation Murphy had with Davis before she died in 1989.

I think ultimately what happened to both women is very painful, Murphy said.

I got to know Bette Davis.

When I [spent four hours with her], she was not that person at all.

And nothing has really changed.

We really wanted to lean into that aspect of the show.

Aging actresses still have the same problem, I can guarantee that, Sarandon added.

Theres agreat Amy Schumer thing, your last fable day in Hollywood, Lange continued with a laugh.

Added executive producer Dede Gardner: I think the show is deeply modern, actually.

I think it calls it out for its truisms and it was brutal.

These women were treated brutally and made to treat one another brutally.

And I dont think much has changed in that regard.

And he said, Well, Im scared too.

And that really helped me a lot.
