“Bridgerton,” Shondaland’s period romp, returns for a fourth season, welcoming another wave of debutants into the marriage market of Regency Era London.

Having skipped ahead to book four of author Julia Quinn’s saga for the third season, the show now backtracks to follow the plo

New faces

Yerin Ha (Sophie Baek)

Coming from a family of actors, Yerin Ha was perhaps destined to become a thesp, but the 28-year-old Australian Korean has found her feet remarkably quickly. She studied musical theater at Sydney’s National Institute of Dramatic Art, graduating in 2018, and was cast the following year in a high-profile production of William Golding’s “Lord of the Flies” at Sydney’s Roslyn Packer Theatre, which also starred Mia Wasikowska and Eliza Scanlen. The production was helmed by increasingly famous stage director Kip Williams, who was clearly impressed with Ha’s work and later cast her in his take on Jean Genet’s “The Maids,” which ran at the Donmar Warehouse in London in 2025.

Her leading role on “Bridgerton” marks her biggest screen role to date, but Ha already has several high-profile screen credits to her name. In 2022, she played Kwan Ha in the video game adaptation “Halo,” produced by Steven Spielberg. She has also featured in HBO’s “Dune: Prophecy” (2024) and Netflix’s “The Survivors” (2025).

Katie Leung (Lady Araminta Gun)

Fans of the “Harry Potter” film franchise will remember Katie Leung’s moving turn as the gentle love interest Cho Chang—a part that’s a world away from Leung’s “Bridgerton” character, the bitter and conniving Lady Araminta Gun. Following her breakthrough performance in the “Harry Potter” movies, the Chinese Scottish actor made her stage debut playing author Jung Chang in an adaptation of Chang’s autobiographical novel “Wild Swans,” which ran at London’s Young Vic Theatre in 2012.

She went on to study her craft at the Royal Conservatoire of Scotland, graduating in 2015. Since then, the 38-year-old has enjoyed a steady career on both stage and screen. Highlights are her roles as reporter Rachel Li in the BBC’s 2024 miniseries “Nightsleeper” and strung-out mom Kristina in the five-strong cast of Branden Jacobs-Jenkins’ “The Comeuppance” at the Almeida Theatre the same year. She’s worked in animation too. Some will recognise her as the voice of Caitlyn Kiramman in the 2021 Netflix animated series “Arcane.”

Michelle Mao (Rosamund Li) 

Her appearance as well-to-do Li sister Rosamund may be 27-year-old Michelle Mao’s most high-profile role to date, but the Chinese American actor isn’t new to the screen. Her IMDb profile boasts almost 50 credits, including roles on TV shows and in music videos and short films. Where did she begin? With extensive training. Mao attended boarding school in England before returning to the States to study at UC Berkeley. She then headed to China, where she earned a Master’s from Beijing’s Tsinghua University, and began her professional career from there.

Isabella Wei (Posy Li)

Hong Kong–born actor and dancer Isabella Wei is most famous for her roles in the Netflix series “1899” (2022) and “Black Doves” (2024). Joining the cast of “Bridgerton” to play the other Li sister, Posy, marks her Netflix triad. Although the screen has kept her busy the past few years, Wei initially trained as a dancer, performing hip-hop, contemporary, and jazz routines at Hong Kong’s Shouson Theatre.

Returning favorites

With introductions out of the way, here’s a refresher on the returning cast members who also play a big role in “Bridgerton” Season 4.

Luke Thompson (Benedict Bridgerton) 

He’s been on the show since the beginning, but this season sees the free-loving ladies’ man smarten up—or perhaps tame?—his act, as he steps into the spotlight to play one half of the focal couple. Benedict is portrayed by 37-year-old English actor Luke Thompson, who has serious stage clout in the UK. He has played major roles in numerous Shakespeare plays at leading theatres, and he earned an Olivier Award nomination for his portrayal of Willem in Ivo van Hove’s stage adaptation of Hanya Yanagihara’s “A Little Life” in 2023. All that came after his studies, of course. Thompson studied English and drama at the University of Bristol before training as an actor at London’s Royal Academy of Dramatic Art (RADA), graduating in 2013.

Claudia Jessie (Eloise)

Thank goodness for the show’s staunchly feminist Eloise, who spends much of Season 4 dodging her mother’s attempts to find her a suitor. Eloquent and self-possessed, she’s the voice of independence—and English actor Claudia Jessie, who portrays her, is every bit as inspirational. She trained part-time at the Susi Earnshaw Theatre School in London before returning to her home city of Birmingham, where she studied for a year with the Birmingham Library Theatre Company. A natural comic, the 36-year-old’s break came playing Shari in the 2014 BAFTA-winning CBBC web series “Dixi.” Further TV success has placed her in the hit police drama “Line of Duty,” an ITV adaptation of William Makepeace Thackeray’s “Vanity Fair,” “Doctor Who” (Season 11, Episode 7), and Jack Thorne’s Netflix miniseries “Toxic Town.”

Ruth Gemmell (Violet, Dowager Viscountess Bridgerton) 

Season 4 holds a meaty (or should we say tea-shaped?) role for Lady Bridgerton, too, as she takes a break from aggressively match-making her offspring to rediscover her own sexuality in the hands of Daniel Francis’ Lord Marcus Anderson. She’s portrayed by English actor Ruth Gemmell, who some may recall from her leading role as Sarah in the 1997 adaptation of Nick Hornby’s “Fever Pitch” opposite Colin Firth or from her recurring part as Detective Constable Kerry Cox in the first season of the BBC police procedural “Silent Witness” (1996)—a show she later returned to as other characters in 2006 and 2014. Millennial readers may think of her as the mother of Jacqueline Wilson’s eponymous character Tracy Beaker. Before her career onscreen, Gemmell trained at prestigious London institution Webber Douglas Academy of Dramatic Art.

Nicola Coughlan (Penelope Featherington) 

What would the “Ton” be without its resident scribe? Lady Whistledown, or Penelope Featherington to her friends, is portrayed by Irish actress Nicola Coughlan, who had already made her name playing school girl Clare Devlin in Channel 4 sitcom “Derry Girls” prior to her “Bridgerton” success. Known for her youthful appearance, Coughlan was already in her early 30s when filming “Derry Girls.” Before that, she’d trained at both the Oxford School of Drama and Birmingham School of Acting. Since her “Bridgerton” fame, Coughlan has received a BAFTA for her portrayal of Maggie Donovan, a young woman juggling bipolar disorder, in the 2024 dark comedy “Big Mood.” She’s had a number of roles onstage, too, most recently playing Pegeen Flaherty in a 2025 revival of John Millington Synge’s “The Playboy of the Western World” at the National Theatre in London.

t of book three, “An Offer From a Gentleman,” which tells the Cinderella-inspired story of the second Bridgerton sibling, Benedict (Luke Thompson), who falls in love with a maid, Sophie Baek (newcomer Yerin Ha), after she infiltrates Lady Bridgerton’s exclusive masked ball under the guise of the mysterious Lady in Silver. Left with only a glove to track her down, and the distraction of the unmasked Sophie Baek—whom he fortuitously meets on a trip to the countryside—Benedict sets about reconciling his feelings.

Meanwhile, plotting to bring Sophie down is Lady Araminta Gun (Katie Leung), an evil step mother–type figure, who’s hoping Benedict will fall for one of her own daughters, Rosamund (Michelle Mao) and Posy (Isabella Wei), who are also debutants.

Here’s a peek behind the masks of the show’s newest cast members, including their training, previous roles, and where you may have seen them before.
