Gene Hackman, who never fit the mold of a Hollywood movie star, but who became one all the same, playing seemingly ordinary characters with deceptive subtlety, intensity and often charm in some of the most noted films of the 1970s and ’80s, has died, the authorities in New Mexico said on Thursday. He was 95.

Mr. Hackman and his wife were found dead on Wednesday afternoon at a home in Santa Fe., N.M., where they had been living, according to a statement from the Santa Fe County Sheriff’s Department. The cause of death was unclear and under investigation. Sheriff’s deputies found the bodies of Mr. Hackman; his wife, Betsy Arakawa, 64; and a dog, according to the statement, which said that foul play was not suspected.

Mr. Hackman was nominated for five Academy Awards and won two during a 40-year career in which he appeared in films seen and remembered by millions, among them “Bonnie and Clyde,” “The French Connection,” “The Poseidon Adventure,” “Mississippi Burning,” “Unforgiven,” “Superman,” “Hoosiers” and “The Royal Tenenbaums.”

The familiar characterization of Mr. Hackman was that he was Hollywood’s perfect Everyman. But perhaps that was too easy. His characters — convict, sheriff, Klansman, steelworker, spy, minister, war hero, grieving widower, submarine commander, basketball coach, president — defied pigeonholing, as did his shaded portrayals of them.
