Cary Grant (born Archibald Alec Leach; January 18, 1904 – November 29, 1986) was an English-American actor. He was known for his Mid-Atlantic accent, debonair demeanor, light-hearted approach to acting, and sense of comic timing. He was one of classic Hollywood's definitive leading men from the 1930s until the mid-1960s. He was nominated twice for the Academy Award for Best Actor, and in 1970 he was presented an Academy Honorary Award by his friend Frank Sinatra at the 42nd Academy Awards. He was accorded the Kennedy Center Honors in 1981. In 1999, the American Film Institute named him the second greatest male star of Golden Age Hollywood cinema, trailing only Humphrey Bogart.

Grant was born and brought up in Bristol, England. He became attracted to theater at a young age when he visited the Bristol Hippodrome. At 16, he went as a stage performer with the Pender Troupe for a tour of the US. After a series of successful performances in New York City, he decided to stay there. He established a name for himself in vaudeville in the 1920s and toured the United States before moving to Hollywood in the early 1930s.

Grant initially appeared in crime films and dramas such as Blonde Venus (1932) with Marlene Dietrich and She Done Him Wrong (1933) with Mae West, but later gained renown for his performances in romantic screwball comedies such as The Awful Truth (1937) with Irene Dunne, Bringing Up Baby (1938) with Katharine Hepburn, His Girl Friday (1940) with Rosalind Russell, and The Philadelphia Story (1940) with Hepburn and James Stewart. These pictures are frequently cited among the greatest comedy films of all time. Other well-known films in which he starred in this period were the adventure Gunga Din (1939) and the dark comedy Arsenic and Old Lace (1944). He also began to move into dramas such as Only Angels Have Wings (1939) with Jean Arthur, Penny Serenade (1941) again with Dunne, and None but the Lonely Heart (1944) with Ethel Barrymore; he was nominated for the Academy Award for Best Actor for the latter two.

During the 1940s and 50s, Grant had a close working relationship with director Alfred Hitchcock, who cast him in four films: Suspicion (1941) opposite Joan Fontaine, Notorious (1946) opposite Ingrid Bergman, To Catch a Thief (1955) with Grace Kelly, and North by Northwest (1959) with James Mason and Eva Marie Saint, with Notorious and North by Northwest becoming particularly critically acclaimed. The suspense-dramas Suspicion and Notorious both involved Grant playing darker, morally ambiguous characters. Toward the end of his career, Grant was praised by critics as a romantic leading man, and he received five nominations for the Golden Globe Award for Best Actor, including for Indiscreet (1958) with Bergman, That Touch of Mink (1962) with Doris Day, and Charade (1963) with Audrey Hepburn. He is remembered by critics for his unusually broad appeal as a handsome, suave actor who did not take himself too seriously, and able to play with his own dignity in comedies without sacrificing it entirely.

Grant was married five times, three of them elopements with actresses Virginia Cherrill (1934–1935), Betsy Drake (1949–1962), and Dyan Cannon (1965–1968). He had daughter Jennifer Grant with Cannon. He retired from film acting in 1966 and pursued numerous business interests, representing cosmetics firm Fabergé and sitting on the board of Metro-Goldwyn-Mayer. He died of a stroke on November 29, 1986 in Davenport, Iowa, aged 82.
