The course of their friendship is shown through extracts from the real diaries and letters of the two men, right up to their last meeting at the Chelsea Physic Garden, when Sassoon was recovering from a head wound that would end his military career while Owen waited to return to the Western Front, where he would be killed shortly afterwards.
Not About Heroes was also performed in the early 1990s at The Round House Theatre in the Maryland suburbs of Washington, D.C. Stephen McGann played Owen in a production at the Oxford Playhouse in 1987, opposite Paul Shelley as Sassoon.
In October/November 2008, Rowan Tree Theatre Co. in the Scottish Borders, mounted a production of the play to mark the 90th anniversary of the end of the Great War and in celebration of the company's twenty-first birthday.
Notable productions of Not About Heroes in recent years have included a version mounted for the 2002 Hay-on-Wye literary festival, starring Roger Moss and Owen Sheers.
Directed by Caroline Clegg, this production went on to be the first theatre company to perform in the Cabinet War Rooms (Churchill's bunker), followed by a national tour and short sell-out season at Trafalgar Studios, Whitehall, London.
Inspired by Not About Heroes at Trafalgar Feelgood created Eloquent Protest a peace event using poetry, song and textas "an artists response to war".
Hosted by retired politician and peace campaigner Tony Benn this became a pivotal event for four years, with stars such as Janie Dee, Johnnie Fiori, Sam West, Robert Powell, Jason Isaacs, Roy Bailey, Julian Littman, Clive Rowe, Peter Straker, Jane Milligan and David Harsent.
RGP Productions produced the play in Sydney, followed by a season at the Australian War Memorial in Canberra in 2007, starring Roger Gimblett as Sassoon and Patrick Magee as Owen, with direction by Carla Moore.
