I was working on the Government’s first national AIDS awareness campaign in 1987 when Princess Diana made a landmark visit that awoke the whole nation.She visited the first AIDS unit at the Middlesex Hospital and in front of the cameras shook the hand of a dying patient, without the Royals’ customary gloves on her hands.Bren Gosling has recreated that hour-long visit , partly from archive material at the National HIV Story Trust , who are joint associates for his production of Moment of Grace.Three actors, Andrew Paul, Lucy Walker-Evans and Luke Dayhill show us three very different but interlinked characters bound up in the day.
