The Hills of California arrives in the West End with an impeccable pedigree. The director is Sam Mendes, the writer is Jez Butterworth. They’ve had hits on stage and screen before (such as Jerusalem for JB, James Bond for Sam Mendes) and they teamed up for Butterworth’s last theatre success The Ferryman. The Hills of California looks set to be another big winner, though maybe not in the Jerusalem league.
