Una Merkel (December 10, 1903 – January 2, 1986) was an American Tony Award-winning stage and film actress.

Una Merkel was born in Covington, Kentucky, and grew up in Philadelphia and New York City. She bore a resemblance to actress Lillian Gish and began her career as a stand-in for Gish, most notably in the 1928 classic The Wind, a late silent film. Merkel appeared in a few films during the silent era, including the two-reel Love's Old Sweet Song (1923) made by Lee DeForest in his Phonofilm sound-on-film process, and starring Louis Wolheim and Donald Gallaher. However, she spent most of her time in New York City working on Broadway.

Merkel returned to Hollywood and achieved her greatest success with the advent of "talkies". She played Ann Rutledge in the film Abraham Lincoln (1930) directed by D. W. Griffith. During the 1930s, Merkel became a popular second lead in a number of films, usually playing the wisecracking best friend of the heroine, supporting actresses such as Jean Harlow, Carole Lombard, Loretta Young, and Dorothy Lamour.

Kenneth Howard "Kenny" Delmar (September 5, 1910, Boston, Massachusetts – July 14, 1984, Stamford, Connecticut) was an American actor active in radio, films, and animation. An announcer on the pioneering radio news series The March of Time, he became a national radio sensation in 1945 as Senator Beauregard Claghorn on Fred Allen's program Allen's Alley. The character Delmar created was a primary inspiration for the Warner Bros. cartoon character Foghorn Leghorn.

Kenneth Frederick Fay Howard was born September 5, 1910, in Boston, but moved to New York City in infancy after the separation of his parents. His mother, Evelyn Delmar, was a vaudevillian who toured the country with her sister. Kenny Delmar was on the stage from age seven. His first screen appearance was in the D. W. Griffith film Orphans of the Storm (1921), in which he played the Joseph Schildkraut role as a child. During the Depression he left the stage to work in his stepfather's business. After running his own own ballet school for a year he married one of his teachers, Alice Cochran, and decided to try a career in radio.

June Lockhart (born June 25, 1925) is an American actress, primarily in 1950s and 1960s television, but with memorable performances on stage and in film too. She is remembered as the mother in two TV series, Lassie and Lost in Space. She also portrayed Dr. Janet Craig on the CBS television sitcom Petticoat Junction (1968–70).

Born in New York City, Lockhart is the daughter of Canadian-born actor Gene Lockhart, who came to prominence on Broadway in 1933 in Ah, Wilderness!, and English-born actress Kathleen Arthur Lockhart. She made her acting debut opposite her parents in a film version of A Christmas Carol, in 1938. She also played supporting parts in films including Meet Me in St. Louis, Sergeant York, All This, and Heaven Too and The Yearling. Lockhart played the title role in She-Wolf of London (1946).

In 1948, Lockhart won a Tony Award for Outstanding Performance by a Newcomer (a category that no longer exists) for her role on Broadway in For Love or Money. And in 1951, she starred in Lawrence Riley's biographical play Kin Hubbard opposite Tom Ewell. In 1955, she appeared in an episode of CBS's Appointment with Adventure. About this time, she also made several appearances on NBC's legal drama Justice, based on case files of the Legal Aid Society of New York. In the late 1950s, she guest starred in several popular television Westerns including: Wagon Train and Cimarron City on NBC and Gunsmoke, Have Gun – Will Travel, and Rawhide on CBS.

Frank James Cooper, known professionally as Gary Cooper, (May 7, 1901 – May 13, 1961) was an American film actor. He was renowned for his quiet, understated acting style and his stoic, but at times intense screen persona, which was particularly well suited to the many Westerns he made. He also excelled in sophisticated, screwball romantic comedies. His career spanned from 1925 until shortly before his death in 1961, and comprised more than one hundred films.

Cooper received five Academy Award nominations for Best Actor, winning twice for Sergeant York and High Noon. He also received an Honorary Award in 1961 from the Academy.

Decades later, the American Film Institute named Cooper among the AFI's 100 Years... 100 Stars, ranking 11th among males from the Classical Hollywood cinema period. In 2003, his performances as Will Kane in High Noon, Lou Gehrig in The Pride of the Yankees, and Alvin York in Sergeant York made the AFI's 100 Years... 100 Heroes and Villains list, all of them as heroes.

Jean Harlow (March 3, 1911 - June 7, 1937) was an American film actress and sex symbol of the 1930s. Known as the "blonde Bombshell" and the "Platinum Blonde" (owing to her platinum blonde hair), Harlow was ranked as one of the greatest movie stars of all time by the American Film Institute. Harlow starred in several films, mainly designed to showcase her magnetic sex appeal and strong screen presence, before making the transition to more developed roles and achieving massive fame under contract to Metro-Goldwyn-Mayer (MGM). Harlow's enormous popularity and "laughing vamp" image were in distinct contrast to her personal life, which was marred by disappointment, tragedy, and ultimately her sudden death from renal failure at the age of 26.

Harlow was born Harlean Harlow Carpenter in Kansas City, Missouri. The name is sometimes incorrectly spelled Carpentier, which came from later studio press releases in an attempt to sound more aristocratic, and the inaccuracy has been frequently repeated. Her father, Mont Clair Carpenter (1877–1974), was a dentist who came from a working-class background and attended dental college in Kansas City. Her mother, Jean Poe Carpenter (née Harlow), was the daughter of a wealthy real estate broker, Skip Harlow, and his wife Ella Harlow (née Williams). The marriage was arranged by Skip Harlow in 1908 and Jean, an intelligent and strong-willed woman, was resentful and became very unhappy in the marriage. The couple lived in Kansas City in a house owned by Skip Harlow.
