The 12-year old Barratt, who featured in the Starz White Princess drama alongside Killing Eve’s Jodie Comer, will play Ray, a 12-year-old boy on trial for murder, in Responsible Child.
The 90-minute drama will air on BBC Two later this year and is produced by Broadchurch producer Kudos and 72 Films.
Owen McDonnell (Killing Eve), Shaun Dingwall (Topboy), Debbie Honeywood (Sorry We Missed You), Angela Wynter (Les Miserables) and James Tarpey (Our Robot Overlords) round out the cast.
Based on real events, the drama is told in two time frames and follows the events that led up to the murder and trial. Ray (Barratt) and his 23-year-old brother Nathan (Tarpey) are arrested after stabbing their mother’s partner.
