The 90-minute drama is an adaptation of the 1987 Ian McEwan novel of the same name.
Cumberbatch plays a children’s author called Stephen Lewis whose three-year-old daughter goes missing. His marriage to wife Julie, played by Kelly Macdonald, disintegrates and their lives descend into freefall.
“I read the novel years ago and it stayed with me – profound, beautiful and very moving,” Cumberbatch said. “Only Ian McEwan could write about loss with such telling honesty.”
The Child in Time is a BBC co-production and will appear on our small screens in 2018. Check out the trailer here:
