Brian Tarantina, a character actor known for playing a comedy club M.C. on the Emmy Award-winning series “The Marvelous Mrs. Maisel,” was found dead on Saturday at his home in Manhattan. He was 60.

His publicist, Laurie Smith, said Mr. Tarantina died of “complications from a severe health crisis he experienced a few months ago.”

About 12:40 a.m., police officers responded to a call reporting an unconscious male inside an apartment in the Hell’s Kitchen neighborhood. Officers said they found Mr. Tarantina unresponsive on his couch and pronounced him dead at the scene. The medical examiner’s office was to perform an autopsy.

[Update: In December, the medical examiner reported that Mr. Tarantina died of an overdose.]

Mr. Tarantina was best known recently for his work on “The Marvelous Mrs. Maisel,” which last year won the Emmy for outstanding comedy series. In the show, he played Jackie, the M.C. at the Gaslight comedy club, where Midge Maisel, the housewife-turned-comic played by Rachel Brosnahan, got her unwitting start.
