With her own company behind the Showtime miniseries ‘George & Tammy’, out now, Chastain was determined to give her “Stand By Your Man’ country singer “main character energy.”

The actor takes issue with the idea that Tammy Wynette was a doormat, reminding us that Wynette was married five times.

The male character of George Jones is played by Michael Shannon, who has an excellent relationship with Chastain.

As scripted, the scene went something like:

DON (picture a pencil neck with an ego): You're going to fuck my wife, aren't you, George?

GEORGE (Michael Shannon): Yes, I'm going to fuck her.

"[Michael] changed the line from, 'Yes, I'm going to fuck her'—excuse the language—to, 'I sure would like to," Chastain remembers. "The second he said, 'I sure would like to,' it was like, 'Oh, yes, this is happening. Because he sees her as someone who gets to make the decision. And that's working with an actor who's very aware he doesn't own me." Another perk of being producer? You get to pick your scenemates. "We were so in tune with one another," says Shannon, who first met Chastain on the set of 2011's Take Shelter. "The notion of sitting in front of another man and looking at a woman and proclaiming that you're going to fuck her, seems a little neanderthal to me. I mean, if I was the woman in question, I wouldn't enjoy that so much."
