The play is based on the true story of Alma Rattenbury (to be played by Duff) who was put on public trial in 1935 with her 18-year-old lover for violently killing her husband. Additional casting will be announced at a later date. The production will launch the 2011 centenary celebrations of Rattigan's birth.
The production will be designed by Hildegard Bechtler, with lighting by Bruno Poet, music by Adrian Johnston, and sound by Ian Dickinson.
Duff won Evening Standard Theatre, South Bank Show, and The Critics' Circle Awards and received an Olivier Award nomination for her 2007 performance in Saint Joan at the National Theatre. Among her other stage credits are King Lear and Collected Stories. In addition, she received BAFTA nominations for Shameless and The Virgin Queen.
