Irish Rep producing director Ciarán O'Reilly directs the contemporary classic set in 1962. The "bittersweet comedy revolves around the young Gar O'Donnell on the eve of his departure from Ireland to America," according to Irish Rep. "Gar's heartache from losing his girlfriend to a successful businessman propels him to accept an invitation to go and live with an aunt in Philadelphia. Despite the wild fantasies of what life in America might hold, and his yearning to escape the tedium of small town Ballybeg, a kind word from his taciturn father could change his mind."
The cast includes Paddy Croft, Michael Fitzgerald, James Kennedy, Edwin Owens, James Stevens, Tessa Klein, Gil Rogers, Helena Carroll, John Leighton, Geddeth Smith, Tim Ruddy, Joe Berlangero, Darren Connolly and Leo Leyden.
Friel's work includes Dancing at Lughnasa, Translations, Aristocrats and Give Me You Answer Do. Born in County Tyrone, Northern Ireland, in 1929, Brian Friel is one of Ireland's major contemporary voices of the past 50 years.
Philadelphia, Here I Come! was first produced on Broadway in 1964 by David Merrick and ran for 326 performances.
