Vincent Dowling, former artistic director of The Abbey Theatre of Dublin, directs. Opening was May 21. The run was originally announced to play to July 5.

According to Irish Rep, "In 1858, two extraordinary men shared a podium to debate issues that would rock the world. Abraham Lincoln and Stephen Douglas, the nation's most charismatic orators, tackled these historic debates with fervor and an energy that hypnotized the nation. Behind the public drama, an equally tantalizing scenario was unfolding."

This year marks the bicentennial of the birth of Abraham Lincoln.

Christian Kauffmann plays Abraham Lincoln, Peter Cormican plays Stephen Douglas, Mary Linda Rapelye is Adele Douglas and Doug Stender is the Republican Committeeman.
