Jean Smart has just won a third Emmy for her starring turn in the Max series “Hacks,” the gleefully sardonic half-hour sitcom set in the rarefied, ruthless world of stand-up comedy.It is her sixth Emmy overall.

“It’s very humbling. It really is. I appreciate this,” Smart said in a low voice, as she accepted the trophy. Then she went in for the punchline. “Because I don’t get enough attention. I’m serious.”

Smart beat out a roster of actresses including Quinta Brunson, the creator and star of “Abbott Elementary,” who won the award in the previous Emmy ceremony, in January; and Ayo Edebiri of FX’s “The Bear,” who moved into the lead actress category after winning best supporting actress in January. Also nominated were Selena Gomez, for “Only Murders in the Building,” and the former “S.N.L.” co-stars Maya Rudolph, for “Loot,” and Kristen Wiig, for “Palm Royale.”

As Deborah Vance, a celebrated comedian enjoying a late-career triumph, Smart, 72, is able to play smart, sexy, callous, vulnerable and very, very funny. In this latest season, she executes a mercenary plan to achieve something typically denied to women: a host gig on a major late-night show.

In May, Smart told The New York Times, “I’ve always been part way to between leading lady and a character actress.” Who could doubt her leading-lady chops now?
