Hollywood actress Sigourney Weaver is to star as a former Vietnam nurse in a BBC Radio 4 play.
Weaver had Oscar nominations for Aliens and Gorillas in the Mist
The Oscar-nominated star will appear in No Background Music on 2 September, playing a woman trying to come to terms with the war years.
She delivers "a moving, courageous performance", according to producer and director Gregory Whitehead.
He said: "Sigourney has the rare ability to convey darkness and warmth, simultaneously, within her voice."
Weaver was the first choice for the role and Mr Whitehead said he was "delighted" when she accepted.
"She also has an outstanding ear for subtle shifts and changes, necessary to pick through the many landmines in the remarkable script," he added.
Weaver is known for roles in films including Alien, Gorillas in the Mist, Working Girl and The Ice Storm.
No Background Music is based on interviews with real Vietnam nurses conducted by US playwright Normi Noel over 12 years.
It has also been revealed that Israeli conductor Daniel Barenboim will present Radio 4's Reith Lectures, to be broadcast in April and May next year.
He will argue that "music lies at the heart of our understanding of what it is to be human and that music provides a way of making sense of the world", a BBC statement said.
