Though Lithgow sees the character he's playing as his polar opposite, there are actually several similarities between the once-famous columnist and the long-famous actor. "I'm a Harvard man; so was he," Lithgow concedes.

"But he was very much a Northeastern Brahmin; he had gone to Groton. I was a public school student."

He continues the comparison: "I studied in England" (on a Fulbright fellowship); "Joe was a pseudo-Englishman," affecting an accent. "And I have a beloved brother." Joe Alsop's brother Stewart collaborated on the newspaper column until 1958, when he broke away to become a magazine journalist. Joe loved Stewart but also tormented him, Lithgow says: "He threw a typewriter at him five times."

Joe's relationship with Stewart (played by Boyd Gaines) is one of several depicted in Auburn's play, which spans the years 1954 to 1968. The others are with his wife (played by Margaret Colin in "a marriage of convenience"), his stepdaughter (Grace Gummer) and the antiwar journalist David Halberstam (Stephen Kunken).

Then there is the relationship with the man from Moscow. "It was known that Joe Alsop was entrapped," Lithgow says. "But it's a dramatization. David's play is hypothetical non-fiction."

Shared alma mater and acquaintances are far from the only similarities between the columnist and the actor playing him. Joseph Alsop was a cultured man, a dedicated art collector who wrote several art history books. As a writer he averaged 1,000 words a day for 50 years, putting together a column three times a week and also penning several books, including a biography of FDR and a memoir published posthumously. Lithgow, too, is a man of letters; he is the author of eight children's books and a memoir, "Drama: An Actor's Education," published last year. He is also a lifelong art lover; he attended the Art Students League as a teenager, fully intending a career as a visual artist, until one decisive evening in December of 1964, when he appeared in an undergraduate production of Gilbert and Sullivan's Utopia, Limited. At the end, the applause was deafening. "That 20 seconds was all it took," Lithgow recalls in his memoir. "There was no longer any question. I was going to be an actor."

Those who knew his background may not have been very surprised: Lithgow's father, Arthur, was a theatre professor, producer and director who cast his youngest son in his productions from an early age.

In a widely varied career that has lasted just about as long as the career Alsop had as a columnist, Lithgow, probably best known as the alien High Commander on TV's "3rd Rock from the Sun," has played a journalist four times.

"They're great characters," he says. Here, too, there are similarities. "Both entertainers and journalists live on adrenaline," says the entertainer playing a journalist. "And everybody is always saying that both theatre and newspapers are dying. Theatre will never die. Neither will journalism."

The old Royal typewriter he uses in The Columnist just might, though. "You can't afford to have the keys stick when you're performing a scene," says Lithgow, "so I've been practicing."
