Sheen returns to the Donmar following his Olivier Award nomination for Best Actor in the title role of Caligula. His other stage credits include The U.N. Inspector at the National and on Broadway, Amadeus in Peter Hall’s 1999 revival of Peter Shaffer’s Tony-winning play.

Morgan’s most high-profile work, written for British television, was also political. Called “The Deal," the piece was a fictionalized account of the leadership deal struck before the 1997 British General Election between Prime Minister hopefuls and Labour MPs, Tony Blair and Gordon Brown.
