Set on April 3, 1968, the play is a reimagining of events the night before the assassination of civil rights leader Martin Luther King, Jr., as he retires to Room 306 in the now famous Lorraine Motel in Memphis, after delivering his legendary 'From the mountaintop' speech to a massive church congregation. The Mountaintop received its world premiere to critical acclaim in a three-week run at Theatre 503 in June 2009, and subsequently transferred to the West End's Trafalgar Studio 1.
