"Best of Enemies" — the Gore Vidal and William F. Buckley debates

From The New York Times article, "Buckley vs. Vidal: When Debate Became Bloodsport," a review by Michael M. Grynbaum of the new documentary, Best of Enemies:

Literary aristocrats and ideological foes, [Gore] Vidal and [William F.] Buckley attracted millions of viewers to what, at the time, was a highly irregular experiment: the spectacle of two brilliant minds slugging it out — once, almost literally — on live television.

Buckley anymore,” Mr. Neville said in a recent interview. “Their lives are the kind of American lives that people don’t have anymore. To me, just on a theatrical level, it seemed operatic: this kind of grand battle.”
