The play will be performed at the Minerva Theatre, Chichester, UK, from June 12 to July 11. Byrne, a Golden Globe winner with two Tony nominations, will play Geoff. James plays Kate, a Tony-nominated stage actress. Prasanna Puwanarajah, who won the 2025 U.K. Theatre Award for best director for his RSC production of "Twelfth Night," makes his CFT debut with the production.
