George Clooney was honored at the USC Shoah Foundation’s Ambassadors for Humanity gala Thursday night at the American Museum of Natural History, where the “Gravity” star was seated with power players including Steven Spielberg, Jerry Seinfeld, Lorne Michaels, Ron Meyer and Sandra Bullock.

Jon Stewart emceed the event, which also marked the 20th anniversary of “Schindler’s List.” Stewart cracked that his mother sent him to the Upper West Side gala with a list — which included lox, bagels and whitefish from Zabar’s.

Norah Jones played tunes and Bullock explained from the stage, while introducing Clooney, that she auditioned for Spielberg’s 1993 smash “Jurassic Park,” but lost the role to Laura Dern and still wants to work with him.

Spielberg is the USC Shoah Foundation’s honorary chair and has helped to create a Visual History Archive of Holocaust and other genocide survivors.

Clooney’s December film, “The Monuments Men,” is about a dramatic race to save art stolen by Nazis.
