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: One of Great Britain's foremost pin-up girls, the delightful Martine Beswicke has managed the neat trick of being kinky and classy all in one. Billed as "Martin Beswick," Beswicke made her first film appearance as one of the fighting gypsy girls in the 1963 James Bond flick From Russia With Love; she returned to Bondland with a more substantial role in Thunderball (1965). After drawing attention away from a near-naked Raquel Welch in One Million Years B.C. (1966), Beswicke was awarded with the leading role in the similar Prehistoric Women (1967). She attracted the notice of the intelligentsia with her performance as a leather-clad lesbian in 1967's Penthouse, then went on to play half the title role in Dr. Jekyll and Sister Hyde (1971). By contrast, her portrayal of Xaviera Hollander in The Happy Hooker Goes to Hollywood was a model of restraint. American TV viewers were given ample opportunity to drink in the charms of Martine Beswicke in the 1979 miniseries The Innocent and the Damned -- not to mention her brief but impressive (and fully clothed) appearance in a well-circulated beer commercial of the early '80s.

Trivia: Supporting actor Lee Wilkof has spent his career alternating among stage, screen, and television. He made his feature film debut in The Serial (1980). His television appearances include guest-starring roles on shows ranging from Law & Order to Newhart.

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: Over-the-top comic actor Kenneth Mars made an unbearably funny screen debut as the ex-Nazi playwright responsible for the smash miss "Springtime for Hitler" in Mel Brooks' The Producers (1968). He was just as exaggerated, though not quite as amusing, as the one-armed police inspector in Brooks' Young Frankenstein (1974). Mars seemingly never held anything back, a trait that was prized by his admirers but caused discomfort among his detractors: reviewing the actor's performance in Peter Bogdanovich's What's Up Doc? (1972), Jay Cocks noted, "As a pompous middle-European intellectual, Kenneth Mars mugs and drools in a manner that Jerry Lewis might find excessive." Still, Mars nearly always delivered the laughs -- especially on TV, where he was a regular on such programs as He and She and The Carol Burnett Show. Another of his screen appearances was as a remonstrative rabbi in Woody Allen's Radio Days (1986). Kenneth Mars has also provided voices for dozens of TV cartoon shows, where he sometimes fell prey to the indignity of having his name spelled Len Mars in the credits.

Trivia: Before becoming a screen and television actor in the early '60s, Charles Shull was the news director of a television station in Richmond, VA.
