Sweetpea: Meet the cast of female serial killer series Sweetpea - including Fallout and Bridgerton stars

Sweetpea , a new Sky Atlantic drama, is the perfect watch for the spooky season - maybe with the doors locked though! From the producers of Heartstopper , this new series follows quiet girl Rhiannon Lewis who is always overlooked and follows how she gains back her power at the people she hates.

Based on the 2017 novel by C.J. Skuse, Rhiannon sometimes makes a list of people she would like to kill. Her life has not been easy so far from her boss at work who won't give her a promotion to her high school bully who's back in town tormenting her. However, things get gory and dark pretty quickly as the female serial killer is no longer keeping her list a fantasy.

The line-up is a storm of rising stars from Bridgerton and Fallout , so who are they and where have you seen them before?

Read on to meet the cast of dark comedy Sweetpea …

Ella Purnell - Rhiannon Lewis

Ella, who plays the lead and is the executive producer of the series, is not a stranger to a darker female role. She's mainly been across the pond in US series such as YellowJackets , which was a thriller series following a group of young soccer girls stranded after a plane crash. More recently, she shot to stardom after being in Amazon’s Original video game adaption Fallout as Lucy MacLean.

Now on her return to the UK, Ella wanted this role to be relatable and not just your everyday female serial killer on screen. Speaking to The Guardian she said: "Women are so often pressured to be likeable and pretty and perfectly packaged, it’s a lot harder to create moral complexity." Rhiannon's inner female rage comes out at everyone around her showing that this is a difficult, dark character to play. So buckle in for not just a gory story but a conflicting coming of age one as well.
