In the mid-1960s, the ESC became involved in issues of censorship. Their premiere productions of Osborne's "A Patriot for Me" and "Saved" by Edward Bond (both 1965) necessitated the theatre turning itself into a 'private members club' to circumvent the Lord Chamberlain, formally responsible for the licensing of plays until the Theatres Act 1968. The "succès de scandale" of the two plays helped to bring about the abolition of theatre censorship in the UK. During the period of Devine's directorship, besides Osborne and Bond, the Royal Court premiered works by Arnold Wesker, John Arden, Ann Jellicoe and N.F. Simpson. Subsequent Artistic Directors of the Royal Court premiered work by Christopher Hampton, Athol Fugard, Howard Brenton, Caryl Churchill, Hanif Kureishi, Sarah Daniels, Errol John, Timberlake Wertenbaker, Martin Crimp, Sarah Kane, Sylvia Wynter, Mark Ravenhill, Martin McDonagh, Simon Stephens, Leo Butler, Polly Stenham and Nick Payne. Early seasons included new international plays by Bertolt Brecht, Eugène Ionesco, Samuel Beckett, Jean-Paul Sartre, and Marguerite Duras. In addition to the 400-seat proscenium arch Theatre Downstairs, the much smaller studio Theatre Upstairs was opened in 1969, at the time a 63-seat facility. "The Rocky Horror Show" premiered there in 1973. The theatre was Grade II listed in June 1972.
