Julia Roberts has recently shared her experience of filming “Gaslit” with Sean Penn, which is set to release in 2022.

The political thriller features a physical fight scene between their characters Martha and John Mitchell, which left Roberts stunned.

During an interview on SiriusXM’s “The Jess Cagle Show,” she revealed that they had a lot of physical scenes in the movie that required a high level of commitment.

Roberts confessed that she had never done many fight scenes in movies before, so she had to put a lot of confidence in Penn.

She said, “Sean and I have known each other since I was a teenager.

And so, I knew that I could trust whatever he was gonna do.

I was gonna survive… he has my husband and children to account for, you know, but I’ll tell you, he wasn’t, it wasn’t a little kiddie soft paws slap.”

She further disclosed that the first fight scene they did was when they slapped each other, and Penn slapped her first.

She admitted being stunned by the force of his slap, saying, “It was quite surprising.” However, she managed to continue performing without showing any discomfort.

Roberts also joked during the interview about the effect of the hard slap, “He told me it seemed to come from the shoulder, so I guess I really had a strong response.”

In addition to discussing the fight scene, Roberts also talked about celebrating her 20th wedding anniversary with her husband, Daniel Moder.

She said that they would celebrate by “more kissing” and joked that they would need “two bathroom sinks and lots of kissing.”

“Gaslit” is based on the true story of Martha Mitchell, the wife of former US Attorney General John Mitchell.

The story revolves around how Martha discovered that her husband was involved in the Watergate scandal and how she tried to expose it.

The movie also stars Sean Penn, Armie Hammer, and Joel Edgerton.

The film’s director, Matt Ross, said in an earlier interview that Roberts was perfect for the role of Martha because of her “incredible intelligence, warmth, and wit.” He also praised Penn’s performance, saying, “Sean is a spectacular actor… He’s incredibly smart and intuitive.”

The upcoming political thriller has already generated much anticipation among the audience due to the impressive cast and intriguing storyline.

The movie will be released on Starz in 2022.

Roberts has been known for her exceptional performances in movies such as “Pretty Woman,” “Erin Brockovich,” and “Wonder.” She has won several awards, including an Academy Award, a Golden Globe Award, and three Screen Actors Guild Awards.

Penn, on the other hand, has also received critical acclaim for his acting in movies like “Mystic River,” “Milk,” and “Dead Man Walking.” He has won two Academy Awards for Best Actor and Best Supporting Actor.
