From a New York Times obit by Neil Genzlinger headlined “Douglas McGrath, Playwright, Filmmaker, and Actor, Dies at 64”:

Douglas McGrath, a playwright, screenwriter, director and actor who was nominated for an Oscar, an Emmy and a Tony Award, and whose one-man Off Broadway show, “Everything’s Fine,” opened just weeks ago, died on Thursday at his office in Manhattan.

His death was announced by the show’s producers, Daryl Roth, Tom Werner and John Lithgow. Their representative said the cause was a heart attack.

Mr. Lithgow also directed the show, a childhood recollection of Mr. McGrath’s about a middle-school teacher in Texas who gave him an inappropriate amount of attention.
