Background: George Orson Welles was born May 6, 1915, in Kenosha, Wisconsin, son of Richard Head Welles (b. Richard Hodgdon Wells, November 12, 1872, near St. Joseph, Missouri; d. December 28, 1930, Chicago, Illinois) and Beatrice Ives Welles (b. Beatrice Lucy Ives, September 1, 1883, Springfield, Illinois; d. May 10, 1924, Chicago).
Context: Simultaneously with his work in the theatre, Welles worked extensively in radio as an actor, writer, director and producer, often without credit. Between 1935 and 1937 he was earning as much as $2,000 a week, shuttling between radio studios at such a pace that he would arrive barely in time for a quick scan of his lines before he was on the air. While he was directing the Voodoo Macbeth Welles was dashing between Harlem and midtown Manhattan three times a day to meet his radio commitments. In addition to continuing as a repertory player on The March of Time, in the fall of 1936 Welles adapted and performed Hamlet in an early two-part episode of CBS Radio's Columbia Workshop. His performance as the announcer in the series' April 1937 presentation of Archibald MacLeish's verse drama The Fall of the City was an important development in his radio career and made the 21-year-old Welles an overnight star. In July 1937, the Mutual Network gave Welles a seven-week series to adapt Les Miserables. It was his first job as a writer-director for radio, the radio debut of the Mercury Theatre, and one of Welles's earliest and finest achievements. He invented the use of narration in radio. "By making himself the center of the storytelling process, Welles fostered the impression of self-adulation that was to haunt his career to his dying day," wrote critic Andrew Sarris. "For the most part, however, Welles was singularly generous to the other members of his cast and inspired loyalty from them above and beyond the call of professionalism." That September, Mutual chose Welles to play Lamont Cranston, also known as The Shadow. He performed the role anonymously through mid-September 1938.

Background: Cary Grant (born Archibald Alec Leach; January 18, 1904 - November 29, 1986) was an English-American actor, known as one of classic Hollywood's definitive leading men. He began a career in Hollywood in the early 1930s, and became known for his transatlantic accent, debonair demeanor, and light-hearted approach to acting and sense of comic timing. He became an American citizen in 1942. Born in Horfield, Bristol, Grant became attracted to theatre at a young age, and began performing with a troupe known as "The Penders" from the age of six.
Context: Stirling refers to Grant as "one of the shrewdest businessmen ever to operate in Hollywood". His long-term friendship with Howard Hughes from the 1930s onward saw him invited into the most glamorous circles in Hollywood and their lavish parties. Biographers Morecambe and Stirling state that Hughes played a major role in the development of Grant's business interests, so that by 1939, he was "already an astute operator with various commercial interests". Scott also played a role, encouraging Grant to invest his money in shares, making him a wealthy man by the end of the 1930s. In the 1940s, Grant and Barbara Hutton invested heavily in real estate development in Acapulco at a time when it was little more than a fishing village, and teamed with Richard Widmark, Roy Rogers, and Red Skelton to buy a hotel there. Behind his business interests was a particularly intelligent mind, to the point that his friend David Niven once said: "Before computers went into general release, Cary had one in his brain". Film critic David Thomson believes that Grant's intelligence came across on screen, and stated that "no one else looked so good and so intelligent at the same time". After Grant retired from the screen, he became more active in business. He accepted a position on the board of directors at Faberge. This position was not honorary, as some had assumed; Grant regularly attended meetings and travelled internationally to support them. His pay was modest in comparison to the millions of his film career, a salary of a reported $15,000 a year. Such was Grant's influence on the company that George Barrie once claimed that Grant had played a role in the growth of the firm to annual revenues of about $50 million in 1968, a growth of nearly 80% since the inaugural year in 1964. The position also permitted use of a private plane, which Grant could use to fly to see his daughter wherever her mother, Dyan Cannon, was working. In 1975, Grant was an appointed director of MGM. In 1980, he sat on the board of MGM Films and MGM Grand Hotels following the division of the parent company. He played an active role in the promotion of MGM Grand Hotel in Las Vegas when opened in 1973, and he continued to promote the city throughout the 1970s. When Allan Warren met Grant for a photo shoot that year he noticed how tired Grant looked, and his "slightly melancholic air". Grant later joined the boards of Hollywood Park, the Academy of Magical Arts (The Magic Castle, Hollywood, California), and Western Airlines (acquired by Delta Air Lines in 1987).
