Blackpool, 1976. The driest summer in two hundred years. The beaches are packed. The hotels are heaving. In the sweltering backstreets, far from the choc ices and donkey rides, the Webb Sisters are returning to their mother's run-down guest house, as she lies dying upstairs.Jez Butterworth's play The Hills of California was first performed at the Harold Pinter Theatre in London's West End in 2024, directed by Sam Mendes, and produced by Sonia Friedman Productions and Neal Street.
