Jessica Chastain details ‘gross’ experience during ‘A Doll’s House’

Jessica Chastain may have needed a breath mint before kissing her co-star in the Broadway play, “A Doll’s House.”

The Oscar winner, 46, got candid on a recent episode of the SmartLess podcast, recalling the worst thing that happened to her while doing the show.

She dished to hosts Will Arnett and Sean Hayes that she vomited moments before she had to smooch her castmate.

“I can say it now, ’cause we’re closed. This is really gross, what I’m gonna tell you guys,” the “Eyes of Tammy Faye” actress began. “I threw up. I threw up and I swallowed it. And no one knew!”

She went on: “I was kinda, like, sobbing and I leaned over and it happened.”

Chastain continued: “I had to kiss someone! Yes! It was a nightmare and I couldn’t explain.”

She noted that the lip lock was “sensual” and a “closed mouth kiss.”

It was when the production finally wrapped that evening that she was able to tell others what ordeal she had gone through.

“The second we had the curtain call and the curtain came down, I said, ‘You guys, I’m so sorry, I vomited,’” she added.

“A Doll’s House” premiered at the Big Apple’s Hudson Theatre on March 9 and ran until June 10. Arian Moayed, Michael Patrick Thornton and Okieriete Onaodowan also starred in the drama.

Chastain has had an impressive few years, with a medley of successful projects, an Academy Award and a Tony nomination for her recent stage production.

She reflected on her career in a new interview with Vanity Fair published earlier this month.

“To have the most incredible past couple of years … It’s also been more of me producing the projects,” the “Zero Dark Thirty” alum explained.

She pointed out: “As women get older in the industry, we need to become more active in producing projects in order for us to have a place here — because no one else will do it for us.”

“I watched the industry for a long time before I had the opportunity of working in it, and I gathered a lot of information. It has changed quite a bit,” Chastain said of how Hollywood has evolved in recent years. “The whole #MeToo culture, which I am appreciative of, the idea that there’s now more resources for people who feel like they’re in an unhealthy, abusive situation. “

She added: “I guess the most that I’ve learned, really, has been the producing side and the development side, and we’ve done a lot at my [production] company [Freckle Films]. We started working in my living room, and we just recently got an office. It’s been a very steep learning curve.”
