Who Plays Diana Mitford On Peaky Blinders?

On Season 6 of "Peaky Blinders," Diana Mitford is introduced as a strong-minded English socialite whose ambitions lead her to the bedroom of British Union of Fascists party leader Oswald Mosley (Sam Claflin). Although she and Mosley are engaged, she meets her match in Thomas "Tommy" Shelby (Cillian Murphy). Intrigued by the gruff crime boss, she cannot resist flirting with him even as he tries to keep his mind on professional matters — and the deadly diagnosis that means his time is running quite short.

The twosome engages in a season-long erotic pas de deux throughout Season 6, which culminates in an intimate encounter that left fans of the show enraged (per The Daily Mail). Tommy's ambitions, as well as his growing attraction to Diana and affair with Gina (Anya Taylor-Joy), ultimately ruin his marriage to Lizzie (Natasha O'Keeffe), who leaves him. In the end, Tommy resists giving into his inclination to cheat with the future Mrs. Mosley a second time and lives to prepare his revenge on her husband-to-be.

The actress behind Diana's fair face is something of a rising star in the entertainment industry but has been gaining recent acclaim. Here's what we know about the person who plays Diana Mitford on "Peaky Blinders" Season 6.

Amber Anderson portrays Diana Mitford

According to her IMDb profile, the actress who plays Diana Mitford on "Peaky Blinders" is Amber Anderson. American audiences may remember her best as Jane Fairfax in the 2020 big-screen adaption of "Emma," which also co-stars Anya Taylor-Joy, or perhaps her role as Sara in the 2013 "Black Mirror" episode, "The Waldo Moment." Her first credited role was in the big-screen comedy "Your Highness" as a singing maiden. Anderson has also appeared in "Skin Walker," "White Lie," for which she was critically lauded during the 2109 awards season (via IMDb), and "In Darkness."

Per The Scotsman, Anderson dug deep into her role in order to play a fictionalized version of her. "I thought it would be fun to try and get in a little bit of Diana really running things behind the scenes with Oswald sometimes being a bit of a drama queen and Diana having to say, 'Don't worry darling, it's fine, I'll sort it out.'" According to Den of Geek, in real life, Mitford was indeed the power behind the throne and hoped Mosley would end up Britain's fascist leader. Instead, they were imprisoned from 1940 to 1943 and were subsequently expelled from England.

Anderson also pointed out how the real-life Mitford and her five sisters led incredibly different lives. An example: While Diana and her sister, Unity, were open about their fascist politics, their sister, Jessica, moved to America and became a communist investigative journalist, per Vanity Fair. To this, Anderson added, "They grew up in a time when women didn't have many rights and freedoms, but their own little universe would have been completely run by women," and concluded, "So it's not a stretch to imagine she would have felt she was the boss of things."
