Game of Thrones star Donald Sumpter is to take a leading role in the new BBC2 drama One Child.
He will play the father of the heroine, Mei, a young Chinese woman who struggles to come to terms with her identity after being adopted by Anglo-American parents.
Katie Leung, who starred as Cho Chang, erstwhile love interest of Harry Potter in the film The Goblet of Fire will play Mei.
US actress Elizabeth Perkins, best known for playing the narcissistic neighbour Celia in the hit comedy drama Weeds, plays Mei's mother in the drama which has been written by veteran screenwriter Guy Hibbert.
John Alexander, who worked on BBC2 serial The 7:39 with Sheridan Smith and David Morrissey earlier this year, will direct.
Executive Producer Hilary Salmon said: “Guy Hibbert is the leading political dramatist of his generation writing for TV. The insight, humanity and sheer moral power he brings to One Child will make it a compelling and moving watch for a BBC2 audience."
Filming has already begun for the series, which will be shot on location in London and Hong Kong. Whilst no release date has been confirmed yet, it is expected that the drama will be broadcast in two 90-minute slots on BBC2 later this year.
