The winners of the 2018 WhatsOnStage Awards were announced last night (25 February), with NHB author Jez Butterworth's mighty drama The Ferryman one of the night's big success stories.

Following its similar recent wins at the Evening Standard and Critics' Circle Awards, The Ferryman duly walked off with the WhatsOnStage Award for Best New Play, also winning Best Director (Sam Mendes) and Best Supporting Actor in a Play (Fra Fee). First seen at the Royal Court in April 2017, the play - a family epic set in the Northern Ireland during the Troubles - is currently enjoying a twice-extended West End run until May, before transferring to Broadway. Also nominated in the Best New Play category were NHB-published Gloria by Branden Jacobs-Jenkins and Oslo by J. T. Rogers.

Elsewhere, there was also a win for Lucy Kirkwood's dazzlingly ambitious drama Mosquitoes, with Olivia Colman taking home the Best Actress award. A play about family and particle physics, set in Geneva as the Large Hadron Collider starts up in 2008, Mosquitoes premiered at the National Theatre in July 2017.
