The emergence of a new drama in the early 20th century had little initial impact on mainstream theatre, but new and dissenting voices slowly
began to transfer onto the West End from the little theatres. The plays of George Bernard Shaw, Somerset Maugham, Terence Rattigan, Noël Coward, and J.B. Priestley,
dominated the West End between the wars. Whilst Priestley and Shaw had a strong left wing agenda, the plays were essentially conservative
in form.
The most successful show of World War 1 was the escapist Chu Chin Chow, an oriental extravaganza with
a huge cast and vast sets. But the spectacular drama of the Victorian era was fading from the West
End,
due in part to the economic affects of the Depression.
Only commercial theatre and particularly the flamboyant Drury Lane musicals of Ivor Novello harked back
to the extravagant staging of a previous era.
Between 1915 and 1923 Lilian Baylis’s Old Vic was the first theatre to produce all of Shakespeare’s plays and provided the starting point
for the formation of national ballet, opera and theatre companies. In the 1930s the Old Vic and the Shakespeare Memorial Theatre in Stratford-upon-Avon
fostered a new generation of stars including Laurence Olivier, Ralph Richardson, John Gielgud, John Mills, Vivien Leigh, Michael Redgrave, Peggy Ashcroft and Flora Robson.
Most European-influenced experimentation could be seen at the tiny club theatres such as the Arts Theatre, the Gate and the Mercury Theatre
in London. The Workers' Theatre Movement developed an agit-prop style influenced by German writers such as Ernst Toller and Unity
Theatre in the 1930s became the hot-house for political theatre in the UK from which many new working class playwrights and performers
emerged.
In the regions the new repertory theatres such as the Gaiety in Manchester and Birmingham Repertory Theatre were committed to producing
a wide variety of drama for local audiences. Their innovative work often included support for new local writers. The reps provided training
grounds for young actors, who learned
their craft in a wide range of roles, from farce to Shakespeare, before going on to act in the West End and on screen.
