Full casting has been announced for Tomcat, which opens at Southwark Playhouse next month.
James Rushbrooke's Tomcat was the winner of the 2015 Papatango New Writing Prize which sees his play performed for a four week run at Southwark.
Directed by Kate Hewitt, the cast will be led by 14-year-old Eleanor Worthington-Cox who won an Olivier Award for Matilda along with the other actresses who played Matilda. The role of Jessie in Tomcat will be her first stage role not shared with other children.
As debate over genetic screening rages, Tomcat questions the lengths to which people will go to keep humanity healthy.
The production features set design by So Here We Are designer Lily Arnold, with lighting by Johanna Town and sound by Richard Hammarton.
Tomcat runs at Southwark Playhouse from 30 October to 21 November 2015.
