Phaedra at the National Theatre started with writer/director Simon Stone making a speech about this being the first run-through. He asked for our indulgence if things didn't quite go smoothly, blaming himself for any issues.
During the opening scene, there was nothing noticeable, the problems came when there were scene changes and subtitles later on - but I'll come back to that because, at its core, this version of the Phaedra story and the performances are superb.
All the action takes place in a glass cube, similar to Yerma at the Young Vic, which Stone also directed. The story is transferred to modern Britain; Phaedra becomes 'Helen' (Janet McTeer), a politician and Oxford graduate from an affluent background.
Her husband Hugo (Paul Chihadi) is a diplomat of Iranian descent - he chose the name Hugo because no one could pronounce his Iranian name.
Helen and Hugo have a grown-up married daughter Isolde (Mackenzie Davis), and a 14-year-old son Declan (Archie Barnes).
We find the family at home, along with Isolde's husband Eric (John Macmillan), teasing and bickering while preparing for the arrival of a guest for dinner. They talk rapidly, interrupting each other or having several conversations at once. It feels relaxed and uninhibited.
When their guest Sofiane (Assaad Bouab), arrives, the atmosphere changes; there is excitement, awkwardness, and curiosity. Sofiane is the son of a Moroccan man Helen had an intense holiday romance with when travelling with Oxford chums as a student.
Sofiane is the spit of his father, who died in a car crash while he was having his affair with Helen.
While not technically a stepson as in the original story, Stone instead has created a more complex dynamic.
