Sweetpea Season 2 Trailer Arrives: Ella Purnell's Killer Wallflower Returns
Sky and Starz have released the first full trailer for Season 2 of Sweetpea, the darkly comic thriller starring Ella Purnell as Rhiannon Lewis, a quiet wallflower who develops what Sky's own promotional copy calls a "coming-of-rage" taste for killing. The trailer lands ahead of a November premiere on Sky in the UK and an early 2027 debut on Starz in the US. Deadline
Season 2 picks up directly after the first season's finale. Rhiannon has landed a promotion at the local newspaper where she works — but she is also contending with a copycat killer, meaning someone else is now replicating her crimes. Deadline
The series is adapted from C.J. Skuse's novel of the same name and produced by See-Saw Films and fanboy in association with Sky Studios. Purnell, known to wider audiences from Fallout and Yellowjackets, serves as an executive producer alongside Kirstie Swain. Selina Lim takes over as lead writer for the new season. Deadline
Four new cast members join the second season: Rish Shah plays Gabriel, described as Rhiannon's romantic interest; Tamsin Greig appears as Liv, the mother of an existing character called AJ; Taj Atwal joins as Freya; and Jenny Walser takes on the role of Daisy. Returning cast includes Jon Pointing, whose credits include the comedy series Big Boys. Deadline; Sky
Starz's official series page describes Rhiannon's arc as stepping into "a new, intoxicating power" while working to keep her killer secret under wraps — a tension the copycat-killer storyline looks set to tighten further. Starz
The release window has been public since at least March 2026, when a first-look image of Purnell in character was released. At that time, CBR, citing The Hollywood Reporter, reported that an exact premiere date had not yet been selected — only the window. CBR
Sky's official YouTube channel originally pitched the series as a "coming-of-rage" thriller in which Rhiannon's vengeful impulses become "liberating," and Starz has since published its own Season 2 first-look trailer video on its YouTube channel. Sky YouTube; Starz YouTube
For viewers who found Rhiannon's first chapter gripping, the second season widens the cast and raises the stakes — a promotion, a copycat, and a secret that gets harder to keep. The full trailer is available now on both Sky's and Starz's YouTube channels.
