Later years

In 1966, when his daughter Jennifer Grant was born, Grant retired from the screen so he could focus on bringing her up and to provide a sense of permanence and stability in her life. He had become increasingly disillusioned with cinema in the 1960s, rarely finding a script of which he approved. He remarked: "I could have gone on acting and playing a grandfather or a bum, but I discovered more important things in life". He knew after he had made Charade that the "Golden Age" of Hollywood was over. Grant expressed little interest in making a career comeback, and would respond to the suggestion with "fat chance". He did, however, briefly appear in the audience for Elvis Presley 's 1970 Las Vegas concert documentary Elvis: That's the Way It Is. In the 1970s, he was given the negatives from a number of his films, and he sold them to television for a sum of over $2 million dollars in 1975 ($11.3 million in 2023).

Morecambe and Stirling argue that Grant's absence from film after 1966 was not because he had "irrevocably turned his back on the film industry," but because he was "caught between a decision made and the temptation to eat a bit of humble pie and re-announce himself to the cinema-going public". In the 1970s, MGM was keen on remaking Grand Hotel (1932) and hoped to lure Grant out of retirement. Hitchcock had long wanted to make a film based on the idea of Hamlet, with Grant in the lead role. Grant stated that Warren Beatty had made a big effort to get him to play the role of Mr. Jordan in Heaven Can Wait (1978), which eventually went to James Mason. Morecambe and Stirling claim that Grant had also expressed an interest in appearing in A Touch of Class (1973), The Verdict (1982), and a film adaptation of William Goldman 's 1983 book about screenwriting, Adventures in the Screen Trade.

In the late 1970s and early '80s, Grant became troubled by the deaths of many close friends, including Howard Hughes in 1976, Howard Hawks in 1977, Lord Mountbatten and Barbara Hutton in 1979, Alfred Hitchcock in 1980, Grace Kelly and Ingrid Bergman in 1982, and David Niven in 1983. At the funeral of Mountbatten, he was quoted as remarking to a friend: "I'm absolutely pooped, and I'm so goddamned old....I'm going to quit all next year. I'm going to lie in bed... I shall just close all doors, turn off the telephone, and enjoy my life". Grace Kelly's death was the hardest on him, as it was unexpected and the two had remained close friends after filming To Catch a Thief. Grant visited Monaco three or four times each year during his retirement, and showed his support for Kelly by joining the board of the Princess Grace Foundation.

In 1980, the Los Angeles County Museum of Art put on a two-month retrospective of more than 40 of Grant's films. In 1982, he was honored with the "Man of the Year" award by the New York Friars Club at the Waldorf-Astoria Hotel. He turned 80 on January 18, 1984, and Peter Bogdanovich noticed that a "serenity" had come over him. Grant was in good health until he had a mild stroke in October that year. In the last few years of his life, he undertook tours of the United States in the one-man show A Conversation with Cary Grant, in which he would show clips from his films and answer audience questions. He made some 36 public appearances in his last four years, from New Jersey to Texas, and his audiences ranged from elderly film buffs to enthusiastic college students discovering his films for the first time. Grant admitted that the appearances were "ego-fodder", remarking that "I know who I am inside and outside, but it's nice to have the outside, at least, substantiated".
