Moving from Paramount to work for both RKO and Columbia in the late 30s, Grant made a string of critically praised and still-popular screwball comedies, including Topper (co-starring with Constance Bennett), The Awful Truth (with Irene Dunne) (both 1937), Bringing Up Baby (1938, with Katharine Hepburn), and His Girl Friday (1940, with Rosalind Russell). In the 40s, he was in the farce Arsenic And Old Lace (1944), the musical biopic Night And Day (playing the role of songwriter Cole Porter) and the drama Notorious (both 1946), and the comedies Mr. Blandings Builds His Dream House (1948) and I Was A Male War Bride (1949). Through the 50s and into the 60s he made comedies and dramas with equal aplomb, including Alfred Hitchcock’s To Catch A Thief (1955), Indiscreet (1958), Hitchcock’s North By Northwest (1959), That Touch Of Mink (1962, with Doris Day), and Charade (1963). Although he aged very well, Grant made his final film in 1966, Walk Don’t Run, retiring from films to work as a director of various international companies, including Fabergé and Western Airlines, as well as the film company, MGM. In 1970, he received a special Academy Award for his Lifetime Achievement In Films, having been unsuccessfully nominated as Best Actor for both Penny Serenade (1941) and None But The Lonely Heart (1944).
