The darkly comic thriller series sees the 'Fallout' star play a young girl who murders those who have wronged her

Ella Purnell series Sweetpea has been renewed for a second season at Sky/Starz. Penned and EP'd by Pure writer Kirstie Swain, Sweetpea follows Rhiannon Lewis, who doesn't make much of an impression – people walk past her in the street without a second glance,

Ella Purnell will continue to seek murderous vengeance against her enemies, thanks to Starz giving Sweetpea a season two renewal.
