Robert Fox, the prolific British theater and film producer whose work bridged London's West End and Broadway, has died at 73. Best known for producing Peter Morgan's play 'The Audience,' which inspired the Netflix series 'The Crown,' Fox built a career championing playwrights like David Hare and Edward Albee.

Coming from a theatrical dynasty - his father was an agent to stars like Paul Scofield and Julie Christie - Fox began his career at London's Royal Court Theatre before partnering with Michael White on groundbreaking productions like 'A Chorus Line' and 'The Rocky Horror Show.' His Broadway credits included the Tony-winning revival of 'Skylight' and Yasmina Reza's 'God of Carnage.'

Fox's influence extended to film, where he produced acclaimed works including 'Iris,' 'The Hours,' and 'Notes on a Scandal.' His collaboration with David Bowie on the musical 'Lazarus' marked a personal highlight. As director Stephen Daldry noted, Fox was 'the cornerstone' of 'The Audience,' serving as executive producer on 'The Crown' and guiding casting and editing decisions. His death from prostate cancer marks the end of an era for British theater production.
