Operation Crucible

First produced in the new writing slot at the Finborough Theatre, Operation Crucible has now been seen across the UK. Including a sell-out run at the Crucible Theatre in Sheffield. In May 2018 the play transferred to New York and played at 59E59 theaters as part of the Brits Off Broadway Season. It was a New York Times Critics pick and enjoyed a sell-out run.


"It is hard to think of another play that captures so efficiently the dividing, before and after, of war’s devastation. And it is all accomplished on a single simple set, with a cast of four and 80 minutes of stage time."

Ben Brantley - New York Times


“Kieran Knowles has fashioned a remarkable first play”

Michael Billington – The Guardian


“A taut, atmospheric study of masculinity, pressure and pride”

Kate Maltby – The Times 


“The camaraderie of the work teams, the excitement and searing heat of the foundry, the indomitable spirit and humour of working-class communities is all gloriously evoked.”

Jonathan Brown – The Independent


“These ghosts, these men and their stories, stay with you”

John Murphy – The Stage
