Screen persona

McCann wrote that one of the reasons why Grant's film career was so successful is that he was not conscious of how handsome he was on screen, acting in a fashion that was most unexpected and unusual from a Hollywood star of that period. George Cukor once stated: "You see, he didn't depend on his looks. He wasn't a narcissist, he acted as though he were just an ordinary young man. And that made it all the more appealing, that a handsome young man was funny; that was especially unexpected and good because we think, 'Well, if he's a Beau Brummel, he can't be either funny or intelligent', but he proved otherwise". Jennifer Grant acknowledged that her father neither relied on his looks nor was a character actor, and said that he was just the opposite of that, playing the "basic man".

Grant's appeal was unusually broad among both men and women. Pauline Kael remarked that men wanted to be him and women dreamed of dating him. She noticed that Grant treated his female co-stars differently than many of the leading men at the time, regarding them as subjects with multiple qualities rather than "treating them as sex objects". Leslie Caron said that he was the most talented leading man she worked with. David Shipman writes that "more than most stars, he belonged to the public". A number of critics have argued that Grant had the rare star ability to turn a mediocre picture into a good one. Philip T. Hartung of The Commonweal stated in his review for Mr. Lucky (1943) that, if it "weren't for Cary Grant's persuasive personality, the whole thing would melt away to nothing at all". Political theorist C. L. R. James saw Grant as a "new and very important symbol", a new type of Englishman who differed from Leslie Howard and Ronald Colman, who represented the "freedom, natural grace, simplicity, and directness which characterise such different American types as Jimmy Stewart and Ronald Reagan", which ultimately symbolized the growing relationship between Britain and America.

Once he realized that each movement could be stylized for humor, the eyepopping, the cocked head, the forward lunge, and the slightly ungainly stride became as certain as the pen strokes of a master cartoonist.

McCann notes that Grant typically played "wealthy privileged characters who never seemed to have any need to work in order to maintain their glamorous and hedonistic lifestyle". Martin Stirling thought that Grant had an acting range that was "greater than any of his contemporaries", but felt that a number of critics underrated him as an actor. He believes that Grant was always at his "physical and verbal best in situations that bordered on farce". Charles Champlin identifies a paradox in Grant's screen persona, in his unusual ability to "mix polish and pratfalls in successive scenes". He remarks that Grant was "refreshingly able to play the near-fool, the fey idiot, without compromising his masculinity or surrendering to camp for its own sake". Wansell further notes that Grant could, "with the arch of an eyebrow or the merest hint of a smile, question his own image". Stanley Donen stated that his real "magic" came from his attention to minute details and always seeming real, which came from "enormous amounts of work" rather than being God-given. Grant remarked of his career: "I guess to a certain extent I did eventually become the characters I was playing. I played at being someone I wanted to be until I became that person, or he became me". He professed that the real Cary Grant was more like his scruffy, unshaven fisherman in Father Goose than the "well-tailored charmer" of Charade.

Grant often poked fun at himself with statements such as, "Everyone wants to be Cary Grant—even I want to be Cary Grant", and in ad-lib lines such as in His Girl Friday (1940): "Listen, the last man who said that to me was Archie Leach, just a week before he cut his throat." In Arsenic and Old Lace (1944), a gravestone is seen bearing the name Archie Leach. Alfred Hitchcock thought that Grant was very effective in darker roles, with a mysterious, dangerous quality, remarking that "there is a frightening side to Cary that no one can quite put their finger on". Wansell notes that this darker, mysterious side extended to his personal life, which he took great lengths to cover up to retain his debonair image. In a profile, Tom Wolfe wrote that "Cary Grant plays a wonderful Cary Grant." Upon being recognized by a fan, Wolfe writes that Grant "cocks his head and gives her the Cary Grant mock-quizzical look—just like he does in the movies—the look that says, 'I don't know what's happening, but we're not going to take it very seriously, are we? Or are we?'"
