At one point in Marie Jones’s “Stones in His Pockets,” an extra in a Hollywood film being shot in County Kerry, Ireland, laments that even that aspect of the Irish economy is dying out. Moviemakers, Jake Quinn says, “have used up most of the 40 shades of green.” There is, however, no end to the shades of green in the Belfast-born Jones’s two-actor, 15-character play, whether it’s the green of the Emerald Isle or the green of the 40 pounds a day that the local extras are receiving. And in the production directed by Courtney O’Connor at the Lyric Stage Company, there’s plenty to think about as well as laugh at.

Jake, on the dole and living with his ma after a short stay in New York, wants to be a film star; the play’s other main character, failed video-store owner Charlie Conlon, has blown in from Antrim with a film script of his own. The movie they’re in, “The Quiet Valley,” has an English director, Clem, and an American leading lady, megastar Caroline Giovanni. Jake and Charlie have to put up with a pair of patronizing assistant directors, Simon and Aisling; Caroline’s inept accent coach, John; and her bodyguard, Jock. Their fellow Irish actors include Mickey, the last surviving extra from John Ford’s 1952 film “The Quiet Man,” and local lad Seán, who won’t survive as an extra on “The Quiet Valley” if he doesn’t lay off the dope and the drink.
