“Dawn’s family were incredibly generous, particularly her parents, in allowing us to speak to them,” Buring continues.
“And they’re such a beautiful family. You can feel the love and the care, and therefore you can more profoundly feel the loss. They are still grieving the loss of a daughter, of a sister, of a mother, of a friend.”
Johnny Harris, best known for his role in This Is England, and whose film Jawbone was hugely well received in 2017, plays Rowley – who he met before filming began.
“We are here to make a TV show. But this is this man’s reality. He lost someone he loved deeply in the most surreal and tragic circumstances,” says Harris.
“So to go anywhere near that you have to be very sensitive. Because, to be quite frank, his treatment at the hands of some sections of the press was atrocious.”
In a wide-ranging interview, Harris also talks about the way the current Covid-19 crisis has changed our ideas about heroes. He sees the way Rowley has handled the trauma as deeply heroic.
“We see statues and blue plaques and all sorts of things up to people that the political elite called heroes. But I’ve got people that I think are heroes. They are the people who make themselves available to you, mothers, nurses, people who turn up anonymously to help others.
“I get a plethora of scripts and I turn down far more than I take on because nine times out of 10 I’m given the role of the misogynistic or homophobic or racist or prejudiced white working class sidekick. I’m just not interested in playing that.
“I want to play people who contribute to the world. I want to tell stories about those kinds of people. And I want to tell stories about their achievements, their role in serving society, why I think those kind of people are heroes. I have always been drawn to marginalised people. It is where I come from. Those are my people.
“I’ve found this public applause for the NHS workers to be deeply moving. I go out every Thursday and find the whole thing very poignant and powerful. And I can only hope that we don’t forget that.”
For the actors, this new drama is built out of a desire to do right by Dawn Sturgess and Charlie Rowley. To alter the collective consciousness about them and to portray them, correctly, as two people in love, who may have been to some dark places but were bringing light back into each other’s lives and planning a happy future.
“The main aim for me was just to try and remind people that this was a real human being that died,” says Buring. “A real human being with highs and lows and joys and sadness… and who ultimately shouldn’t have died.”
I met an amazing human being that has experienced something in life that is extraordinary
For Harris, making this drama has had another uplifting outcome.
“I went to meet Charlie with an open heart. And like with anything in life, if you go into it with an open heart and an open mind, something always happens,” he says.
“The project is over. He’s seen it and I’ve seen it. So that part of the relationship is done now, I guess. But what’s come out of it that was unexpected was a really lovely connection and friendship that continues to this day.
“I met an amazing human being that has experienced something in life that is extraordinary. And the grace and dignity that he’s come through that with still moves me greatly.”
