The winners of the 38th Olivier Awards were announced yesterday (13 April), with Nick Hern Books plays and authors landing no fewer than twelve prizes across a wide range of categories, including the trio of Best New Play, Best New Comedy and Best Revival.

Lucy Kirkwood's gripping thriller Chimerica was the most successful production on the night, winning a total of five awards: Best New Play, Best Director, Best Set Design, Best Lighting Design and Best Sound Design (both shared).

A gripping political examination and engaging personal drama about an American photojournalist searching for the subject of his most famous photograph - the mysterious Tiananmen Square Tank Man - Chimerica enjoyed a hit West End transfer to the Harold Pinter Theatre last summer, following its initial sell-out run at the Almeida Theatre. It has also won the Evening Standard and Critics' Circle Awards for Best New Play, and the Susan Smith Blackburn Prize. Last year, Lucy was also named as the UK recipient of the inaugural Berwin Lee Playwrights Award, a major new prize designed to build links between the UK and US new writing scenes.

NHB author Richard Eyre's production of Ghosts landed three prizes: Best Revival, Best Actress and Best Supporting Actor.

An intense, fast-paced version of Ibsen's classic tragedy both adapted and directed by Eyre, Ghosts opened at the Almeida Theatre in September 2013 to critical acclaim - with Time Out's Andrzej Lukowski declaring it 'the most lucid and affecting version of the play I have ever seen' - before transferring to Trafalgar Studios in December. A Broadway production is apparently in the works.

On the musicals front, Once, with music & lyrics by Glen Hansard & Markéta Irglová and a book by NHB author Enda Walsh, bagged two prizes: Best Actress in a Musical and Outstanding Achievement in Music.

A charming and irresistible musical based on the Academy Award-winning film, Once tells the story of an Irish busker and a young Czech woman who meet on the streets of Dublin, and strike up an intense, blossoming friendship grounded in a shared love of songwriting. Originally seen on Broadway - where it won eight Tony Awards, including Best Musical and Best Book - Once opened at the Phoenix Theatre, West End, in 2013.

Best New Comedy was won by  Jeeves & Wooster in 'Perfect Nonsense', the Goodale Brothers' play based on the works of P. G. Wodehouse.

An inventive, fast-paced comedy featuring Wodehouse’s iconic double act, the play opened at the Duke of York's Theatre, London following preview performances in Richmond and Brighton. It has recently extended booking until September.

Finally, NHB author Rory Kinnear scooped the Olivier Award for Best Actor for his performance as Iago in the National Theatre's production of Othello. Kinnear was similarly recognised at both the Evening Standard and Critics' Circle Theatre Awards.

We'd like to extend our sincere congratulations to the winners - the scripts to all four are avaiable to buy via this website.

Highlights of the Olivier Awards ceremony, which took place at the Royal Opera House, Covent Garden, are available to watch on the ITV website until 12 May.
