It was to have closed Jan. 8.

Previews began Nov. 16. The evening of two works features Pinter's first play (The Room) and his most recent (Celebration). The Room is set in a shabby one-room flat in London, while Celebration takes place in a trendy restaurant where one of three couples is celebrating a wedding anniversary. Both plays, according to a production statement, "resonate with the human desperation to find safe haven in a threatening world." The works were written 40 years apart.

Pinter was awarded the Nobel Prize Oct. 13. Atlantic artistic director Neil Pepe directs the Off-Broadway double bill.

Celebration (presented first on the bill) includes Blumberg, Pittu and Betsy Aidem, Patrick Breen, Brennan Brown, Phillip Goodwin, Carolyn McCormick, Ryan and Christa Scott-Reed.

The Room features Atlantic Company members Kate Blumberg, Mary Beth Peil, David Pittu as well as Earle Hyman, Peter Maloney and Thomas Jay Ryan. Scenic design is by Walt Spangler, lighting design by David Weiner, costume design by Ilona Somogyi and sound design by Obadiah Eaves. Casting is by Bernard Telsey Casting. Production stage management is by Darcy Stephens.

The Caretaker in 1959 is considered to be Pinter's breakthrough play. "He was responsible for the creation of a spare language of verbal evasion and menace, both unspoken and vividly expressed," according to ATC notes. The Swedish Academy, which awards the Nobels, noted, "Pinter restored theatre to its basic elements — an enclosed space and unpredictable dialogue where people are at the mercy of each other and pretense crumbles."

I Celebration and The Room play Tuesdays through Fridays at 8, Saturdays at 2 & 8 and Sundays at 3 PM. All tickets are $50 and are available by calling Telecharge at (212) 239-6200 (Telecharge.com).
