Holgate replaces the previously announced Tony Roberts, who has withdrawn from the production "to attend to family matters," according to a press release.
The three-person cast also includes John Cullum and Jonathan Hogan.
Ron Holgate won a Tony Award for his performance in the original production of 1776 and was Tony-nominated for his work in The Grand Tour. He has also been seen on Broadway in Kiss Me, Kate; Annie Get Your Gun; Lend Me a Tenor; Musical Chairs; The Grand Tour; Saturday Sunday Monday; A Funny Thing Happened on the Way to the Forum; and Milk and Honey.
Directed by Keen artistic director Carl Forsman, the comedy, which was translated by Tom Stoppard, will begin performances at Off-Broadway's Clurman Theatre Feb. 24 and continue through April 11. Opening night is March 8.
Heroes, according to press notes, is an "evocative comedy about three World War I veterans living in a veterans' home who plot a new assault – a trip to a stand of poplar trees in the distance. But should they bring the stone dog with them?" Sibleyras says the play, a 2006 Olivier Award winner for Best Comedy, is "about the universal desire to escape the confines of life."
The production will feature scenic design by Beowulf Boritt, costume design by Theresa Squire, lighting design by Josh Bradford and sound design by Will Pickens.
