It was a Palladino night, indeed. “If I get into a fight, I’ll let you know,” Amy Sherman-Palladino told me on Tuesday evening, giggling beside her longtime creative partner and husband, Daniel Palladino, when I asked them to keep me posted on any drama that might unfold. Together, they eyed the crowd, who sipped pink cocktails and white wine on the rooftop of Fouquet’s, a hotel in New York’s Tribeca neighborhood, for Air Mail and Amazon’s celebration of Étoile, the latest series written, produced, and directed by the Palladinos.

It wasn’t just the couple’s quick-fire repartee—familiar to anyone who’s watched Gilmore Girls and The Marvelous Mrs. Maisel—that made this a Palladino night. Nor was it Sherman-Palladino’s eccentric style, though that was on display in the form of fluffy black cat ears poking out of her hair. More than anything, what made it a Palladino night were the guests, an idiosyncratic mix only this couple could conjure: part Hollywood, part literati; part uptown, part downtown; old guard as well as new.
