Starring Julia Roberts and Sean Penn, Gaslit is an eight-episode dramatic series that debuted just before the 50th anniversary of then-President Richard Nixon’s politically fatal Watergate Scandal. This modern take on the series of events leading to Nixon’s 1974 resignation focuses on the lesser-known figures involved in uncovering the scandal.

How does the cast of Gaslit compare to their real-life counterparts? See for yourself.

The outspoken socialite Martha Mitchell was married to Nixon’s campaign chair and onetime US Attorney General John Mitchell. Martha was one of the first people to uncover the scandal after she overheard her husband’s conversations. Her claims were first attributed to mental illness, but she was vindicated as facts about the case emerged. In 2022, Netflix released a documentary titled The Martha Mitchell Effect, which chronicles her experiences as a whistle-blower during the Watergate Scandal.

As Martha, Julia Roberts wears lavish clothing and dramatic accessories, similar to styles that she favored. Hair stylist Terrie Velazquez-Owen recreated two of Martha’s favorite hairstyles during the 1970s, but tweaked them to fit Julia’s facial structure. As Velazquez-Owen told Womens Wear Daily:

“We weren’t trying to make a replica of Martha. We were trying to bring out Julia’s best features, too. A lot of the styles were not so flattering [on Roberts]. Martha had a rounded-out face and Julia is more angular, so I couldn’t do some of these really severe hairstyles.”

Sean Penn as John Mitchell

John Mitchell served as Attorney General of the United States under Nixon until he resigned in 1972. He then went on to manage the president’s re-election campaign. When the Watergate break-in occurred, John hired a former FBI agent to stop Martha from learning about it. When she went public with the information, he denied her claims, and his involvement in the Watergate affair eventually led to him receiving a sentence of up to eight years in prison.

Sean Penn is barely recognizable in the role, thanks to a full prosthetic face, along with a bald head cap that took hours to get into. Gaslit‘s creator Robbie Pickering spoke to Vanity Fair about Penn’s transformation.

“I was astounded because I couldn’t see where the seams in it were — where Sean’s face began and John Mitchell’s face ended and vice versa,” he said. “It also retained the humanity and warmth in Sean’s face, which is his most underrated quality as an actor.”

Later convicted of conspiracy, burglary and illegal wiretapping, attorney and FBI agent G. Gordon Liddy co-organized and directed the burglary of the Democratic National Committee Headquarters in the Watergate building in May and June 1972. One of Nixon’s most zealous defenders, Liddy became a radio talk show host after serving 52 months in federal prison for his actions.

Actor Shea Whigham portrays Liddy in Gaslit, with a dyed black mustache and matching hair. In an interview with, he addressed the physical aspects of playing such a complicated character.

“Before I take on any role… There’s animal work involved in all of it. That’s where the body stuff comes from,” he explained. “Liddy was a hyena. To me, he was a hyena. He would do anything. You should feel that under any scene, that he would do anything that it took.”

Dan Stevens as John Dean

John Dean served as White House Counsel for President Richard Nixon from July 1970 until April 1973. Dean helped to cover up the scandal and later pleaded guilty to a single felony in exchange for becoming a key witness for the prosecution. This led to a reduced sentence, after which he penned a series of books about his experience. He was also a commentator on contemporary politics, and in 2019 testified before the House Judiciary Committee on the Mueller Report.

Former Downton Abbey star Dan Stevens replaced Armie Hammer in the role of John Dean. Interestingly, Stevens had a chance to meet with Dean in person before filming began. He ultimately passed on the opportunity, though.

“I was keen to sit down with him,” Stevens told The Guardian. “Then I was told I’d have to speak with Universal’s lawyers in advance, which I didn’t want to do; I didn’t think it would make the meal taste particularly nice.”

Betty Gilpin as Mo Dean

Maureen “Mo” Kane Dean married John Dean in 1972. Known by the press as a beautiful “ice queen,” she calmly sat behind her husband during the Watergate hearings and famously wore her hair in a bun every day during his testimony. After the scandal, Mo worked as a stockbroker and released a book in 1975 called Mo: A Woman’s View of Watergate. She also co-wrote a fictional book, titled Washington Wives.

Speaking about working with actress Betty Gilpin, who plays Dean, set makeup artist Tricia Sawyer shared this on Instagram, “I loved working with the wonderful Betty Gilpin on Gaslit. Always game for more…. More lashes…. More tan….. More nail polish.”
