A four-course dinner, highlighted with videos displayed on flat-screens throughout the trendy West Village restaurant, ended with a champagne toast and chocolate cake. Well-wishers included “The Wolf of Wall Street” stars Leonardo DiCaprio and Jonah Hill, “Gangs of New York” star Daniel Day-Lewis, “Taxi Driver” star Harvey Keitel, “Boardwalk Empire” stars Steve Buscemi and Michael Pitt, as well as Steven Spielberg, Patricia Clarkson, Fran Lebowitz, Elvis Costello, Emily Mortimer and Michael J. Fox.
