Jada Pinkett Smith is loving the “sister solidarity” between Jessica Chastain and Octavia Spencer.

In an upcoming untitled movie, second-time co-stars, Chastain and Spencer, fought for a favoured nations clause together.

A favoured nations clause “describes the treatment given to a particular individual – it is a form of protection accorded to a single counterparty, to assure them that no similarly-situated counterparty is getting a better deal than they are,” reads the Entertainment and Media Law Signal’s website.

But Pinkett-Smith made sure to give a public “props” to “sister” Chastain, “Jessica said to Octavia, ‘I got you.’”

“‘I’m going to Universal and we’re going to make a favoured nations deal.’ Jessica stood up for Octavia,” Pinkett-Smith said during a panel at Sundance Film Festival. “I want you to know that they stood together, they got three times what they were asking for as a unit.”

“It’s nice to go out and march, we can do that. It’s nice to wear black to the Golden Globes,” Pinkett-Smith added. “It’s nice to do that, but what are we doing behind closed doors?”

She continued, “I gotta’ give our sister Jessica Chastain her props because she stood up for Octavia and put it down.”

Spencer says she’s grateful for Chastain’s support, and in an interview with The Hollywood Reporter, Spencer shared their story.

“I said, ‘But here’s the thing, women of colour on that spectrum, we make far less than white women. So, if we’re gonna have that conversation about pay equity, we gotta bring the women of colour to the table. And I told her my story, and we talked numbers, and she was quiet, and she said she had no idea that that’s what it was like for women of colour,” Spencer said.

“I love that woman because she’s walking the walk and she’s actually talking the talk,” she continued. “[Jessica] said, ‘Octavia, we’re gonna get you paid on this film.”

And the pair negotiated together.

“She said, ‘You and I are gonna be tied together,” Spencer added. “We’re gonna be favoured nations, and we’re gonna make the same thing, you are going to make that amount.’ Fast-forward to last week, we’re making five times what we asked for,”

Chastain has also explained why she felt this was an important conversation, “She had been underpaid for so long,” she wrote to Twitter.

“When I discovered that, I realized that I could tie her deal to mine to bring up her quote. Men should start doing this with their female co-stars.”

And Twitter agrees, many are loving Chastain’s unconditional support for her co-star.
