[4][16] The play featured an ensemble cast of around 40,[17] including Catherine Tate, Mark Gatiss, Timothy West,[18] Nina Sosanya and Bill Paterson.
Describing the live broadcast, director Rourke said, "This is a unique opportunity for the Donmar to make a small theatre feel very big",[22] whilst writer Graham added that he hoped to illuminate the "diverse, diligent and often hilarious individuals" who turn the "unglamourous" settings of polling stations into "places where history is made".
[21] In 2019, the play was updated into a one-off rehearsed reading production for that year's general election, held on 12 December at Bush House.
[23] All the original cast members reprised their roles, with the exception of Judi Dench, Timothy West, Bhasker Patel, Kadiff Kirwan, Alice Hewkin, Madalena Alberto and Chukwudi Iwuji, who were respectively replaced by Susan Brown, Gawn Grainger, Sartaj Garewal, Calvin Demba, Shaofan Wilson, Lisa Caruccio Came and Nonso Anozie.
James Graham himself read out the lines of Catherine Tate's character's brother, Colin Henderson, while Simon Russell Beale was the narrator.
