Suranne Jones: 'Filming The Crimson Field made me cry'
The series is the 35-year-old actress's first period drama and sees her play spirited nurse Joan Livesey, who joins the staff at a field hospital in northern France which cares for those who are injured at the front.
The Crimson Field has been meticulously researched and is filmed on a purpose-built set in Wiltshire, and one scene in particular made her feel very emotional.
"I don't want to sound too silly about it, but there was one day where they said, 'Action' and there was one of our supporting artistes had pretend blood on him. But he couldn't actually see where he was going because he had been bandaged up and he was just left wandering and no one had told him where to go," Suranne tells TV & Satellite Week.
"It was weird, but I started crying and I grabbed this poor guy’s hand and he was just happy for me to guide him to a bed. It just really made me wonder, should a big disaster happen, how would I react? I like to think I'd roll my sleeves up and get on with pretty much anything and in the show there is all this horror coming in, but they group together and support each other."
The Crimson Field premieres on Sunday on BBC1.
