Trivia: A versatile, commanding, leathery character actor, he learned to raise and ride broncos on his family's ranch during his youth. He attended college for two years, became a seaman, then began his performing career as a radio announcer; he became nationally known as an announcer on the "March of Time" broadcasts. Onscreen from the late '40s, he often portrayed law officers; he was also convincing as a villain. He was well-known for his TV work; he starred in the series Naked City and Wagon Train. He was married to actress Jeanette Nolan, with whom he appeared in Saddle Tramp (1950) and Two Rode Together (1961); they also acted together on radio, and in the late '60s they joined the cast of the TV series The Virginian, portraying a married couple. Their son was actor Tim McIntire.

Trivia: A former University of Illinois sociology major, ash-blonde leading lady Barbara Bain studied for a theatrical career at New York's Actors Studio and Neighborhood Playhouse. While attending an actor's workshop in 1956, Barbara made the acquaintance of an intense young performer named Martin Landau. It was love at first sight, and they married in 1957. Landau and Bain strove to maintain separate careers, and while her husband tended to work more often than she did, Barbara was well-represented with guest appearances on such series as Richard Diamond, Private Detective, Get Smart and The Dick Van Dyke Show. In 1964, the Landaus worked together for the first time on an episode of The Greatest Show on Earth. They didn't care much for the experience, and vowed not to co-star again -- at least, not until producer Bruce Geller made them an offer they couldn't refuse with the weekly TV suspenser Mission: Impossible. Cast as silken espionage agent Cinammon Carter, Bain won three consecutive Emmies for her work on the series (if you're wondering why Cinammon never adopted elaborate disguises, as did practically everyone else on the program, it is because Bain suffered from claustrophobia, and could not abide being hemmed in by heavy makeup). Then, after three seasons' worth of Mission: Impossible, the Landaus quit the series in 1969, citing poor scripts and insufficient creative challenges. In later years, Bain would comment ruefully that leaving the show ruined her career. The record doesn't quite bear this out: indeed, during the early 1970s she racked up an impressive list of TV movie appearances, and was offered a great deal of money to reteam with Landau in the syndicated sci-fi TV series Space: 1999 (1975-77). In 1989, Bain appeared in her very first theatrical feature, Trust Me (1989), playing a truculent, dishonest art collector. Though long-divorced from Martin Landau, Barbara Bain did not express an aversion to the possibility of playing a cameo alongside her ex-husband in the 1996 film version of Mission: Impossible, should either one of them be asked to do so (alas, they weren't).

Trivia: Already a character player in his 30s, American actor Robert Cornwaithe was frequently called upon to play scientific and learned types in such films as War of the Worlds (1953) and The Forbin Project (1971). He was also busy on TV, portraying lawyers, officials and the like on such series as The Andy Griffith Show, Batman (in the "Archer" episode with Art Carney), Gidget, Laverne and Shirley and The Munsters. Cornwaithe earned his niche in the Science Fiction Film Hall of Fame for his performance in The Thing (1951); grayed up, bearded, and looking suspiciously Russian, the actor played the foolhardy Professor Carrington, whose insipidly idealistic efforts to communicate with the extraterrestrial "Thing" nearly gets him killed. In honor of this performance, Robert Cornwaithe was cast as a similar well-meaning scientist in "Mant," the giant-insect film within a film in Joe Dante's Matinee (1993), wherein Cornwaithe shared screen time with two equally uncredited horror-film icons, William Schallert and Kevin McCarthy.

Trivia: Trained as a musician, Virginia Gregg drew her first professional paychecks with the Pasadena Symphony. Gregg was sidetracked into radio in the 1940s, playing acting roles in an abundance of important California-based network programs. Her extensive radio credits include Gunsmoke, Suspense, Yours Truly Johnny Dollar, and Richard Diamond. Her first film was 1946's Notorious, directed by Alfred Hitchcock, who last cast Gregg as the voice of "Mother" in his classic chiller Psycho (1960). Virginia Gregg was most closely associated with the output of actor/producer/director Jack Webb: she co-starred in both of Webb's film versions of his popular radio and TV series Dragnet, and guest-starred in virtually every other episode of the 1967-70 Dragnet TV revival.

Trivia: The son of actress Nan Kelly Yorke, Jack Kelly was the younger brother of stage and film star Nancy Kelly. Like Nancy, Jack was a professional from an early age, acting in radio and on stage before the age of 10, and in films from 1937 (he is quite prominent in a brace of 1939 20th Century-Fox films, Young Mr. Lincoln and The Story of Alexander Graham Bell). He reemerged as a leading man in the early 1950s, appearing in such films as Forbidden Planet (1956, as the ill-fated Lieutenant Farnam). Signed by Warner Bros. in 1955, Kelly starred as Dr. Paris Mitchell in the weekly TV version of the 1942 film King's Row. He went on to play gamblin' man Bart Maverick on the longer-running Warners western series Maverick. Though his popularity never matched that of his co-star James Garner, Kelly still developed a fan following as Bart; he remained with the series from 1957 until its cancellation in 1962, appearing opposite such Garner successors as Roger Moore and Robert Colbert. Kelly dabbled in a little bit of everything after that: hosting the anthology series NBC Comedy Playhouse (1973), emceeing the game show Sale of the Century (1969-71), and playing hard-nosed Lt. Ryan on the Teresa Graves series Get Christie Love (1974) and Harry Hammond on The Hardy Boys/Nancy Drew Mysteries (1977-79). He revived the Bart Maverick character on 1978's The New Maverick and the 1990 TV movie The Gambler Returns: Luck of the Draw. Chances are that, had he lived, Jack Kelly would have been invited to co-star again with Garner in the 1994 Mel Gibson theatrical-feature version of Maverick.

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.
