Jack Thorne's Mydidae is a play for two actors that lays bare a complex relationship over twenty-four hours. It was commissioned by DryWrite theatre company and first performed at Soho Theatre, London, on 5 December 2012.
The play, set entirely in a bathroom, follows a young couple – Marian and David – through the course of a day, from morning ablutions through to a horribly failed attempt at a candle-lit romantic bath in the evening and its chastened aftermath. It is gradually revealed that this is the anniversary of a devastating event, and the fissures in the couple's relationship are finally exposed.
The play's title derives from a family of short-lived stinging flies.
The premiere production was directed by Vicky Jones and designed by Amy Jane Cook, with PhoebeWaller-Bridge as Marian and Keir Charles as David. The production subsequently transferred to the Trafalgar Studios, London, on 5 March 2013.
In his introduction to Jack Thorne Plays: One (Nick Hern Books, 2014), Thorne writes of Mydidae: '[The play] came out of my obsession with [actor] PhoebeWaller-Bridge. ... She and [theatre director] Vicky Jones came to me with a commission to write a play set in a bathroom. I thought I might enjoy that and said yes as long as Phoebe would be in it. ... I think it’s less a play about intimacy than about fear of intimacy. It’s a play about exposing your wounds to someone else and hoping they don’t say "You’re horrendous."'
