The Sarah Ruhl play will get added shows Sunday, March 30 at 2:30 PM and 7:30 PM. This is absolutely the final extension, PH promises. The added performances are expected to sell quickly.

Ruhl is a Pulitzer Prize finalist who penned The Clean House and Eurydice.

The wildly popular production, which was sold out before it even began its run, most recently added two performances for Saturday, March 29 — and both performances sold out "instantly."

Directed by two-time Obie Award winner Anne Bogart (artistic director of SITI Company), Dead Man's Cell Phone is making its New York City premiere. It marks the return to the stage of Tony, Emmy and two-time Golden Globe winner Mary-Louise Parker (Proof, "Weeds"). The play began previews Feb. 9 and opened March 4 for a limited engagement at Playwrights Horizons' Mainstage Theater at 416 W. 42nd Street.

Mary-Louise Parker is joined by Kathleen Chalfant, T. Ryder Smith, David Aaron Baker, Carla Harting and Kelly Maurer. In the quirky comedy, "Gordon (Mr. Smith) is dead, but his cell phone lives on. When Jean (Ms. Parker), an empathetic museum worker, answers his ringing phone beside her in a café, she is soon playing unwitting comforter and confessor to the man's grieving friends and family. Before she knows it, Jean is ensnarled in the underbelly of the dead man's bizarre life. A wildly imaginative new comedy, Dead Man's Cell Phone is the odyssey of a woman forced to confront her assumptions about morality, redemption and the need to connect in a technology-obsessed world."
