Trivia: Redheaded leading man Robert Horton attended UCLA, served in the Coast Guard during World War II, and acted in California-based stage productions before making his entree into films in 1951. Horton's television career started off on a high note in 1955, when he was cast in the weekly-TV version of King's Row as Drake McHugh (the role essayed by Ronald Reagan in the 1942 film version). The series barely lasted three months, but better things were on the horizon: in 1957, Horton was hired to play frontier scout Flint McCullough in Wagon Train, which became the highest-rated western on TV. Horton remained with Wagon Train until 1962. He then did some more stage work before embarking on his third series, 1965's The Man Called Shenandoah. When this one-season wonder ran its course, Horton toured the dinner-theatre circuit, then in 1982 accepted a major role on the popular daytime soap opera As the World Turns. Horton continued acting until the late 1980s. He died in 2016, at age 91.

Trivia: After racking up impressive stage credits in Canada and the U.S., actor Lloyd Bochner familiarized himself with American televiewers in the supporting role of Captain Nicholas Lacey in the prime-time TV serial One Man's Family (1952). Dozens of guest-star assignments later, Bochner again showed up on a weekly basis as police chief Neil Campbell in Hong Kong (1960). His later TV series stints included The Richard Boone Show (1963, as a member of Boone's "repertory company"), and Dynasty (1981-1982 season, as Cecil Colby). In films from 1963's Drums of Africa, Bochner has been seen in such characterizations as Marc Peters in the Carol Lynley version of Harlow (1965) and Dr. Cory in The Dunwich Horror (1969). By far, Bochner's most memorable assignment was the 1962 Twilight Zone episode "To Serve Man," as the scientist who learns all too late that "It's a cookbook!"; nearly 30 years later, he parodied this deathless moment in Naked Gun 2 1/2: The Smell of Fear (1991). Lloyd Bochner is the father of Emmy-winning actor Hart Bochner.

Trivia: American actress Karen Steele usually lived up to her name by playing tough, hard-shelled characters. After her 1955 movie debut, she co-starred in several Budd Boetticher-directed films (The Rise and Fall of Legs Diamond, etc.). Karen Steele's TV guest roles in the 1960s included Mary Jack Armstrong, "the strongest female enemy agent in the world," on Get Smart, and Eve in the 1966 Star Trek episode "Mudd's Women."

Trivia: Kevin Hagen is a veteran character actor long associated with intense dramatic roles. He has portrayed everything from hitmen and rapists to prosecutors and police officers, but is perhaps best known to television audiences for his portrayal of the avuncular Dr. Baker on the long-running series Little House on the Prairie. Hagen was born and raised in and around Chicago, but moved to Portland, OR, during his teens. Following a two-year hitch in the United States Navy, he attended college on the G.I. Bill, majoring in international relations, and later worked for the U.S. State Department in Germany. Bored with that job, he considered a career in law but dropped out after one year. While trying to figure out what he wanted to do for a career, he auditioned for a production of the play Blind Alley and won a small role, despite the fact that he had never acted before. Within a year, Hagen had moved up to playing the lead in a production of James Thurber's play The Male Animal, and spent the next few years scraping out a living in small theatrical productions around Los Angeles in between studying with Agnes Moorehead, among other notables. His breakthrough came with his portrayal of stern patriarch Ephraim Cabot in a production of Eugene O'Neill's Desire Under the Elms -- that led to his getting an agent and, in turn, led to his television debut in an episode of Dragnet. He appeared in various dramatic anthology shows and played important guest-star parts on programs such as Gunsmoke, Rawhide, Cheyenne, M-Squad, and The Untouchables -- in one episode of the latter, "Stranglehold," Hagen brought a startling degree of humanity and depth to the part of a professional killer. Hagen made his feature-film debut in 1958 in the Disney-produced The Light in the Forest, and that same year, he got his first regular role in a series when he was cast in the part of John Colton, the city administrator of post-Civil War New Orleans, in Yancy Derringer. The show only ran for one season, but Hagen had more work than ever following the conclusion of filming, on such series as Bonanza, Perry Mason, The Man From U.N.C.L.E., The Felony Squad, and Mission: Impossible. He also did some film work, most notably in Andrew V. McLaglen's Civil War drama Shenandoah (1965), in which Hagen played the scavenging deserter who murders James Stewart's son (Patrick Wayne) and rapes and murders Stewart's daughter-in-law (Katharine Ross). During this period, he also began a string of appearances in television series produced by Irwin Allen, guest starring in episodes of Lost in Space, Voyage to the Bottom of the Sea, and Time Tunnel. Those roles led to Hagen's being cast as Inspector Kobick, the security officer pursuing the diminutive earthlings, in Allen's Land of the Giants. He brought a great deal of humanity and complexity to his portrayal of the character in the course of the series' two-season run. During the 1970s, Hagen made frequent guest appearances on series such as M*A*S*H, Quincy, and Knot's Landing. In 1974, Hagen was cast in the role for which he has become best known, as Dr. Baker in Little House on the Prairie. He portrayed the part for ten seasons and developed a serious fandom among the series' legions of viewers. Hagen left Hollywood for Oregon in the early '80s, and has continued his work in regional theater productions of such plays as West Side Story, Follies, and Oklahoma! He also performs his own one-man show, a mixture of songs, monologues, and prairie wit and wisdom drawn from his Little House persona.
