Heinie Conklin (July 15, 1889 – July 30, 1959) was an American actor of the silent film era, who appeared in nearly 400 films. Claimed to be one of the original Keystone Kops, Conklin's silent screen makeup consisted heavy eyebrow lining and a thinnish, upside-down, painted-on variation of Kaiser Wilhelm's moustache. He was born in San Francisco, California.

In areas where anti-German sentiments still ran high during the post-World War I era, Conklin was billed as Charlie Lynn. One of Conklin's first talking pictures was All Quiet on the Western Front as a hospital patient. For the rest of his career in talking pictures, he had small roles in 2-reelers which starred The Three Stooges, Andy Clyde, Hugh Herbert and Harry Langdon. Conklin's last billed movie was Abbott and Costello meet the Keystone Kops. He died in Hollywood, California.

Conklin's period at Keystone was contemporary with that of Chester Conklin, a more popular Keystone comedian who occasionally played lead roles in Keystone short films. The two Conklins were not related.

Lew Ayres (born Lewis Frederick Ayres III; December 28, 1908 – December 30, 1996) was an American actor, best known for starring as Paul in All Quiet on the Western Front and for playing Dr. Kildare in several movies, which was apt since originally he had studied medicine at the University of Arizona.

Ayres was born in Minneapolis, Minnesota and reared in San Diego, California. Ayres began acting in bit player roles in films in 1927. He was discovered that year playing banjo in the Henry Halstead Orchestra as Halstead was recording one of the earliest Vitaphone movie shorts called Carnival Night in Paris (Warner Brothers, 1927). Ayres wrote, "I was a member of Henry Halstead's orchestra in 1927 at the Mission Beach Ballroom in San Diego, California for the summer. My instruments were tenor banjo, long-neck banjo and guitar. After a hiatus, I rejoined Mr. Halstead with a new group, including Phil Harris, on New Year's Eve the same year for the opening night of the Beverly Wilshire Hotel, a memorable occasion."

Marion Mitchell Morrison (born Marion Robert Morrison; May 26, 1907 – June 11, 1979), better known by his stage name John Wayne, was an American film actor, director and producer. An Academy Award-winner, Wayne was among the top box office draws for three decades, and was named the all-time top money-making star. An enduring American icon, he epitomized rugged masculinity and is famous for his demeanor, including his distinctive calm voice, walk, and height.

Wayne was born in Winterset, Iowa but his family relocated to the greater Los Angeles area when he was four years old. He found work at local film studios when he lost his football scholarship to USC as a result of a bodysurfing accident. Initially working for the Fox Film Corporation, he mostly appeared in small bit parts. His acting breakthrough came in 1939 with John Ford's Stagecoach, making him an instant star. Wayne would go on to star in 142 pictures, primarily typecast in Western films.

Among his best known films are The Quiet Man (1952), which follows him as an Irish-American boxer and his love affair with a fiery spinster played by Maureen O'Hara; The Searchers (1956), in which he plays a Civil War veteran who seeks out his abducted niece; Rio Bravo (1959), playing a Sheriff with Dean Martin; True Grit (1969), playing a humorous U.S. Marshal who sets out to avenge a man's death in the role that won Wayne an Academy Award; and The Shootist (1976), his final screen performance in which he plays an aging gunslinger battling cancer.

Shirley Jane Temple (born April 23, 1928), later Shirley Temple Black, is an American film and television actress, singer, dancer, autobiographer, and former U.S. Ambassador to Ghana and Czechoslovakia. She began her film career in 1932 at the age of three, and in 1934, found international fame in Bright Eyes, a feature film designed specifically for her talents. She received a special Juvenile Academy Award in February 1935, and film hits such as Curly Top and Heidi followed year after year during the mid-to-late 1930s. Licensed merchandise that capitalized on her wholesome image included dolls, dishes, and clothing. Her box office popularity waned as she reached adolescence, and she left the film industry at the age of 12 to attend high school^{[clarification needed]}. She appeared in a few films of varying quality in her mid-to-late teens, and retired completely from films in 1950 at the age of 22. She was the top box-office draw four years in a row (1935–38) in a Motion Picture Herald poll.

Myrna Loy (August 2, 1905 – December 14, 1993) was an American actress. Trained as a dancer, she devoted herself fully to an acting career following a few minor roles in silent films. She was originally typecast in exotic roles, often as a vamp or a woman of Asian descent, but her career prospects improved following her portrayal of Nora Charles in The Thin Man (1934). Her successful pairing with William Powell resulted in 14 films together, including five subsequent Thin Man films. In 1937, she was crowned the "Queen of Hollywood" by a nationwide poll.

Loy was born Myrna Adele Williams in Helena, Montana, to Adelle Mae (née Johnson) and rancher David Franklin Williams, in nearby Radersburg. Her paternal grandparents were natives of Wales, and her maternal grandparents were Swedish and Scottish. Her first name came from a train station whose name her father liked. Her father was also a banker and real estate developer and the youngest man ever elected to the Montana state legislature. Her mother studied music at the American Conservatory of Music in Chicago.
