By general consent, The Real Thing expresses an almost perfect balance between the brilliance of its dialogue and the ideas examined on one hand, and the depth and range of human feelings on the other. Anna Mackmin’s brisk and dynamic take on the play, first performed nearly 30 years ago, to a large extent succeeds in recontextualising what is surely a classic, for a subsequent generation of viewers.

As anyone who has ever had the misfortune to sit through a real court case knows, they can be deadly dull; but by golly when playwrights get their hands on them they usually become riveting. And so it proves here in Trevor Nunn’s pacy, funny and moving production of Jerome Lawrence and Robert E Lee’s 1955 play.
