Starz’s new comedy-drama show,Sweetpea, is a thrilling miniseries that follows Rhiannon Lewis becoming a killer after her life falls apart. The story takes place in South England and features a talented cast predominantly consisting of British actors who nail their roles, creating both a hilarious yet gripping atmosphere. The cast is led by Ella Purnell, who has become a household name following the success ofFalloutearlier in 2024. While she played an endearing vault dweller with a heart of gold in her Prime Video series,Ella Purnell’sSweetpearole is the opposite of herFalloutcharacter.
Her incredible performance suggests thatSweetpeahas the potential to be amongElla Purnell’s best TV shows, as is the case for the rest of the cast. The show has a real charm that is helped by how ordinary and realistic most of the characters are, as they convey a casual working-class setting in England that is made more exciting by Rhiannon’s descent into madness.Sweetpea’s early reviews indicate it may be one of the best-limited shows of 2024, and it wouldn’t be possible without such a well-crafted cast who expertly brings this compelling story to life.

Kick-Ass 2
Dolce
Character:Purnell plays Rhiannon Lewis, the protagonist ofSweetpea’s chaotic story. Although she starts the series as a seemingly quiet and innocent girl, her rage grows as her life spirals out of control, turning her into a killer. Rhiannon is full of stress and anxiety, having been bullied throughout her childhood, and continuing to feel invisible takes its toll on her. Despite maintaining a normal life as a receptionist in a newsroom, her life completely transforms after getting a taste for killing, making her an exciting yet oddly sympathetic central character, even with her obvious flaws.

Having featured in popular shows likeCasualty,Fresh Meat, andThe Bill, Lecky is no stranger to a variety of genres and roles that have helped prepare her for Starz’sSweetpea.Lecky also led her own miniseries titledMood, which is her most recognizable part to date, and she even wrote the project, highlighting her creativity and flexibility within the television industry.
Bloods
Yasmine
Character:Lecky’s character, Julia, is the main source of Rhiannon’s trauma. Having gone to school with Rhiannon when they were kids, Julia was one of the popular girls who often poked fun at and teased the protagonist. Now, Julia has moved on from her days as a school bully and crafted a seemingly perfect life with a stable job and an attractive partner. Even now, she still looks down at Rhainnon and is often patronizingly nice when convenient, but deep down, Julia doesn’t seem to have changed much, making her the easiest-to-hate character in the entire show.
Jonathan Pointing as Craig
Date of Birth: September 1986
Actor:Jon Pointing was born in South London and has gone on to forge a successful career over the past 12 years. Best known for his comedy work, Pointing has been involved in plenty of British sitcoms alongside a few dramas.Pointing’s first major role came inPlebs, where he played one of the central characters, Jason, and his performance led to some more big parts during the following years.

Queenie
Tom Blake
Character:Jonathan Pointing plays Craig inSweetpea, a romantic interest for Rhiannon who works at her dad’s business. Although he is seemingly nicer to Rhiannon than some of the other characters who treat her like a ghost, Craig is still guilty of completely overlooking the protagonist. He is charming and friendly, yet comes across as a little self-centered at times, even if it’s unintentional. Pointing’s character is definitely one of the more interesting members ofSweetpea’s cast, and his relationship with Rhiannon adds plenty of depth to the show.
Calam Lynch as AJ
Date of Birth: June 29, 2025
Actor:Calam Lynch was born in Warwickshire, England, and is one of the most prolific actors inSweetpea’s cast, despite his relatively short career.

Lynch was a major part ofBridgertonseason 2 as Theo Sharpe, which provided him success in a mainstream show.

Mrs Wilson
Gordon Wilson
Character:Calam Lynch plays AJ, a junior reporter who works for the same newspaper as Rhiannon. Contrary to most other characters in the show, AJ treats Rhiannon surprisingly well and is one of the few characters who actually interacts with her on a basic human level. His family connections allow him to essentially walk into the vacant role at the Gazette, but he doesn’t come across as entitled. Instead, he’s willing to work for his position - even if he’s a little inexperienced - and is easily one ofSweetpea’s most wholesome characters.
Leah Harvey as Marina
Date of Birth: June 01, 2025
Actor:Like some of their costars, Harvey was born in East London. With a history in theater, Harvey received an acting degree in 2016 and began their professional career shortly after, although they did technically earn their first credit in 2008’sDustbin Baby.

Tuesday
Nurse Billie
Character:Harvey plays Marina inSweetpea, a detective who is looking into the murders committed by Rhiannon. Although Marina isn’t the lead investigator, she takes the case more seriously than her boss and appears far more competent, making her the biggest threat to discovering the truth about Rhiannon. A good judge of character and headstrong, Marina seems to be one of the most intelligent characters throughout the entire series and exactly the sort of problem Rhiannon wants to avoid as her lust for blood continues to grow.
Sweetpea’s Supporting Cast & Characters
Jeremy Swift as Norman:Norman runs the Gazette and is Rhiannon’s boss who barely notices her. Seeing her as little more than someone to answer the phone and make him coffee, he comes across as a neglectful superior who Rhiannon resents.
