Sweetpea Season 2: Release date speculation, cast and plot details – Everything we know so far

Hey, if anyone binged the first season of Sweetpea back in October 2024, that twisted ride with Ella Purnell as the ultimate overlooked girl gone rogue totally hooked a ton of viewers. The dark comedy thriller hit Sky Atlantic and Starz, and just two months later in December 2024, they greenlit season 2. Rhiannon Lewis, the quiet wallflower snapping and turning killer, clearly struck a chord with that mix of rage, humor, and outright chaos.

Sweetpea Season 2 Release Date Speculations

Still no exact premiere date out there for Sweetpea season 2. Shooting started up in London around August 2025 and officially wrapped in November 2025 – Ella Purnell spilled that detail herself in a recent chat. Looking back, the first season filmed late 2023 and landed in October 2024, so folks are guessing a similar gap. That could mean late December at the earliest, but most outlets are betting on sometime in 2026 to give post-production plenty of breathing room.

Sweetpea Season 2 Expected Cast

Ella Purnell is front and center again as Rhiannon Lewis, diving deeper into her killer vibe. Plenty of season 1 favorites stick around, like:

• Nicôle Lecky as Julia
• Jon Pointing as Craig
• Leah Harvey as detective Marina
• Jeremy Swift playing the newspaper boss
• Calam Lynch as AJ (though things get complicated there)
• Others including Dustin Demri-Burns, Luke McGibney, and Ingrid Oliver

A few faces from the first run aren’t returning – details are hush-hush, but Just Jared mentioned three exits to shake things up.

Fresh blood joins the fun too. Tamsin Greig pops in as Liv, AJ’s mom. Rish Shah plays Gabriel, a hot new love interest for Rhiannon. Taj Atwal steps up as Freya, her tough new boss at the Carnsham Gazette, and Jenny Walser is Daisy, this super intense new pal who gets way too attached.

The cast feels bigger overall, matching those ramped-up stakes everyone keeps teasing.

Sweetpea Season 2 Potential Plot

Season 2 jumps right in with Rhiannon’s deadly secrets getting messier. After channeling all that built-up anger last time, now the fallout hits hard – her kills spiral, questions about right and wrong pile on, and she wrestles with if she’s straight-up becoming a monster. That promotion at work, new romance, and nosy people circling her past crank the pressure way up.

The official tease from Sky and Starz says Rhiannon returns “with a vengeance” and gets “more twisted than ever.” Producers promise an “intoxicating ride” full of wicked laughs, wild kills, and moral gray areas. It pulls from C.J. Skuse’s books but veers off in fun ways, digging into female rage with zero apologies.

Purnell hyped it as “crazy” and “big,” hinting at more emotional punches, bigger set pieces, and those signature brutal-yet-funny moments. Expect Rhiannon juggling her double life while new folks like her boss and obsessive friend throw everything off balance.
