Trivia: One of the precious few actors of the "pretty boy" school to survive past the 1950s, Robert Wagner was the son of a Detroit steel executive. When his family moved to Los Angeles, Wagner's original intention of becoming a businessman took second place to his fascination with the film industry. Thanks to his dad's connections, he was able to make regular visits to the big studios. Inevitably, a talent scout took notice of Wagner's boyish handsomeness, impressive physique, and easygoing charm. After making his unbilled screen debut in The Happy Years (1950), Wagner was signed by 20th Century Fox, which carefully built him up toward stardom. He played romantic leads with ease, but it wasn't until he essayed the two scene role of a shellshocked war veteran in With a Song in My Heart (1952) that studio executives recognized his potential as a dramatic actor. He went on to play the title roles in Prince Valiant (1954) and The True Story of Jesse James (1956), and shocked his bobby-soxer fan following by effectively portraying a cold-blooded murderer in A Kiss Before Dying (1955). In the early '60s, however, Wagner suffered a series of personal and professional reverses. His "ideal" marriage to actress Natalie Wood had dissolved, and his film career skidded to a stop after The Pink Panther (1964). Two years of unemployment followed before Wagner made a respectable comeback as star of the lighthearted TV espionage series It Takes a Thief (1968-1970). For the rest of his career, Wagner would enjoy his greatest success on TV, first in the mid-'70s series Switch, then opposite Stefanie Powers in the internationally popular Hart to Hart, which ran from 1979 through 1983 and has since been sporadically revived in TV-movie form (a 1986 series, Lime Street, was quickly canceled due to the tragic death of Wagner's young co-star, Savannah Smith). On the domestic front, Wagner was briefly wed to actress Marion Marshall before remarrying Natalie Wood in 1972; after Wood's death in 1981, Wagner found lasting happiness with his third wife, Jill St. John, a longtime friend and co-worker. Considered one of Hollywood's nicest citizens, Robert Wagner has continued to successfully pursue a leading man career into his sixties; he has also launched a latter-day stage career, touring with his Hart to Hart co-star Stefanie Power in the "readers' theater" presentation Love Letters. He found success playing a henchman to Dr. Evil in the Austin Powers movies, and in 2007 he began playing Teddy, a recurring role on the hit CBS series Two and a Half Men.

Trivia: Born Stefania Federkiewicz, she is a lead actress of routine Hollywood films of the '60s and '70s. Soon after graduating from Hollywood High, she debuted onscreen in 1961; early in her career she was billed as Taffy Paul. She starred in the TV series Girl from U.N.C.L.E. and Hart to Hart. From 1966-74 she was married to actor Gary Lockwood, then she became the constant companion of aging actor William Holden; following his death in 1981, she continued being active with the William Holden Wildlife Foundation, which worked to create a big-game preserve and study center in Kenya.

Trivia: Tom Mankiewicz came from a distinguished film family; his father, Joseph L. Mankiewicz, was a renowned director (All About Eve) and his uncle, Herman Mankiewicz, was also a highly respected screenwriter (Citizen Kane). Following studies at the Exeter Academy and Yale, Mankiewicz worked as a production associate on a 1964 film, The Best Man. A few years later, he became a screenwriter. In the early '80s, he directed some episodes of the television series Hart to Hart, and in 1987 he directed his first feature film, Dragnet. Mankiewicz also worked as a script consultant on a few James Bond films and on two of the Superman films. He died of cancer in late July 2010, at age 68.

Trivia: The career of William Prince dates back to his first stage work in the late '30s. On film, Prince came across as handsome and personable, but somehow, despite the fact that he appeared in numerous feature films, his career never caught fire and major movie stardom eluded him. His best movie role was as the good-looking but vapid Christian in the 1950 Cyrano de Bergerac. Ageing gracefully into a solid character actor, Prince remained in demand for film and TV roles into the 1990s. William Prince's latter-day TV reputation rested on his hundreds of soap opera appearances: He played Ken Baxter on Another World, Ben Travis on The Edge of Night, Judge Henderson on Search for Tomorrow, Russell Barry on A World Apart, and the father of the title character in Young Dr. Malone. Prince passed away at age 83 in Tarrytown, NY.
