Executive producers are Helen Gregory for Pinewood Television; Benedict Cumberbatch, Adam Ackland and David Boulter for Sunny March TV; Lucy Richer for the BBC; Rebecca Eaton for Masterpiece; and Stephen Butchard.
The 40-year-old actor and his 48-year-old co-star were spotted working on the movie on Friday afternoon (July 7) at Central Park in Atlanta, Ga.
After graduating, Benedict continued his training as an actor at the London Academy of Music and Dramatic Art (LAMDA).
The son of actors Timothy Carlton and Wanda Ventham, he took his father's birth name of Cumberbatch as his professional name.
Cumberbatch will executive produce and star in the 90-minute film, with Stephen Butchard adapting Mc Ewan’s novel and Julian Farino directing. The film will explore the dark territory of a marriage devastated by the loss of a child: Cumberbatch will play children’s author Stephen Lewis, who must cope with the sudden loss of his daughter, Kate.
