Ron Silver, the Tony Award-winning actor who amassed an impressive list of roles based on real-life figures in movies including "Reversal of Fortune" and "Ali," died Sunday. He was 62.

Silver, a longtime liberal political activist who became an outspoken supporter of former President George W. Bush's military response to 9/11, died of esophageal cancer in New York, according to Robin Bronk, executive director of the Creative Coalition, which he helped found.

During his nearly four-decade career, Silver appeared in films such as the critically acclaimed "Enemies: A Love Story," a 1989 tragicomedy in which he starred as a married immigrant Polish Jew living in post-World War II Coney Island and having an affair.

On TV, he received Emmy Award nominations for his supporting role in the 1987 miniseries "Billionaire Boys Club" and, in 2002, for his recurring role as presidential campaign advisor Bruno Gianelli on "The West Wing."

On Broadway, he won both a Tony Award and a Drama Desk award in 1988 for best actor as the loathsome Hollywood movie producer in David Mamet's "Speed-the-Plow" -- "the performance of his career," proclaimed New York Times critic Frank Rich.

But through the years, Silver's steady work as an actor vied with his off-stage role as a political activist.

He campaigned for Bill Clinton for president; attended the Democratic national conventions in 1992 and 2000; and vocally expressed liberal views on abortion, gay rights, stem cell research and other issues.

But the terrorist attacks of Sept. 11, 2001, marked a turning point for the actor-activist, who delivered a rousing endorsement of Bush at the Republican National Convention in 2004.

"The president is doing exactly the right thing," exclaimed Silver, who brought the cheering delegates to their feet, "and that is why we need this president at this time."

In a 2005 interview with The Times, Silver said, "It sounds like a conversion tale, but I was not reborn. It was fairly consistent with my views in the past. I've been a very aggressive liberal interventionist in my foreign policy feelings. I have felt for a long time that the withdrawal of American power was far more dangerous than getting involved."

He quickly discovered, however, that his backing of the Bush administration took something of a toll in Hollywood.

"There have been a few occasions when people have said, 'I won't work with that S.O.B.,' " he said. "It has happened, but on an individual basis. It is not in any way, shape or form a blacklist.

"In this business, there are a million different reasons people don't want to work with you: You're too Jewish, you're not Jewish enough, they want a bigger star, they think you cost too much money. Most people are very economical with the truth out here, so it's very hard to determine cause and effect."

As for those who mock celebrity participation in politics, Silver told the New York Times in 1993: "What do you want us to do? Have affairs? Become drug addicts? We have a certain visibility and power in the society. We're a celebrity-driven society. Why not use that to try to do a little good?"

In 1989, Silver became founding president of the Creative Coalition, a nonprofit, nonpartisan social and political advocacy organization made up of arts and entertainment figures.

He served as president of the Actors' Equity Assn., the labor union that represents actors and stage managers, from 1991 to 2000.

And he was a founding member of One Jerusalem, an educational foundation with a goal of "maintaining a united Jerusalem as the undivided capital of Israel."

Silver, who attended Columbia University's Graduate School of International Affairs, also was a member of the Council on Foreign Relations, as well as being a member of the program committee of the Woodrow Wilson International Center for Scholars, and a founding member of the board of directors for New York City Public/Private Initiatives Inc.

As he told the New York Times in 1993, "I'm an actor by calling but an activist by inclination."
