Trivia: Red-headed, freckle-faced Martin Milner was only 15 when he made his screen debut in Life With Father (1947), and would continue to play wide-eyed high schoolers and college kids well into the next decade. His early film assignments included the teenaged Marine recruit in Lewis Milestone's The Halls of Montezuma (1951) and the obnoxious suitor of Jeanne Crain in Belles on Their Toes (1952). His first regular TV series was The Stu Erwin Show (1950-1955), in which he played the boyfriend (and later husband) of Stu's daughter Joyce. More mature roles came his way in Marjorie Morningstar (1957) as Natalie Wood's playwright sweetheart and in The Sweet Smell of Success (1957) as the jazz musician targeted for persecution by Winchell-esque columnist Burt Lancaster. Beginning in 1960, he enjoyed a four-year run as Corvette-driving Tod Stiles on TV's Route 66 (a statue of Milner and his co-star George Maharis currently stands at the Corvette Museum in Bowling Green, KY). A longtime friend and associate of producer/director/actor Jack Webb, Milner was cast as veteran L.A.P.D. patrolman Pete Malloy on the Webb-produced TV weekly Adam-12, which ran from 1968 to 1975. His later TV work included a short-lived 1970s series based on Johan Wyss' Swiss Family Robinson. Later employed as a California radio personality, Martin Milner continued to make occasional TV guest appearances; one of these was in the 1989 TV movie Nashville Beat, in which he was reunited with his Adam-12 co-star Kent McCord. He made an appearance on the short-lived series The New Adam-12 and had recurring roles on shows like Life Goes On and Murder, She Wrote. Milner died in 2015, at age 83.

Trivia: The son of a garage mechanic, Glenn Corbett was sent to live with his grandparents at the age of two. He later joined the Seabees and it was during his Navy years that he met his future wife, Judy, a speech major at Occidental College. With Judy's encouragement, Corbett began trying out for campus theatricals. His performance in Occidental's staging of The Caine Mutiny Court Martial led to his being signed by Columbia Pictures. After two year's worth of nondescript roles in films like The Mountain Road (1960) and Homicidal (1961), he landed the lead in the picturesque 1962 TV series It's a Man's World. Though the series lasted only 13 weeks, it gained enough of a cult following to assure Corbett's future stardom. In early 1963, he made a guest appearance as troublesome ex-G.I. Linc Case on the long-running series Route 66; by the fall of that year, he was appearing in that series on a weekly basis, as a replacement for defecting Route 66 star George Maharis. After the series ran its course in 1964, Corbett went on to co-star as Chance Reynolds in the prime-time Western The Road West, which lasted a single season (1966-1967). He kept busy in theatrical features, appearing with John Wayne in Chisum (1969) and Big Jake (1971), and starring in director Sam Fuller's West German-produced Dead Pigeon on Beethoven Street (1972). He went on to play Paul Morgan during the 1983-1984 season of Dallas, returning to the role in 1988. In his last years, he occasionally worked as a dialogue director. Glenn Corbett died of lung cancer in 1993.

Trivia: Born to a well-to-do Massachusetts family, Tammy Grimes studied drama at Stephens College in Missouri (where one of her instructors was George C. Scott) and New York's Neighborhood Playhouse. Grimes made her off-Broadway debut in the 1956 production The Littlest Revue. In 1959, she won a Theatre World Award for her performance in Look After Lulu; the following year, she graduated to full stardom in the long-running musical The Unsinkable Molly Brown, for which she won the first of her two Tony Awards. She rapidly became typed as a flamboyant, plummy-voiced "kook," a characterization that worked just fine on stage but did not adapt so easily to the more intimate medium of film. Perhaps as a result, Grime's film appearances have been few and far between. In 1966, she starred on the TV sitcom The Tammy Grimes Show, which was axed after three episodes; to clear herself for this assignment, she'd turned down the role of Samantha on Bewitched, which lasted eight seasons. From 1956 through 1960, Tammy Grimes was married to actor Christopher Plummer; their daughter, Amanda Plummer, is an excellent stage and film actress in her own right.

Trivia: Horace McMahon dabbled in professional and semi-professional acting while attending Fordham University Law School, continuing to do so while holding down a day job as a newspaper reporter. He made acting his full-time vocation after his first Broadway appearance in 1931. In films from 1937, the growly, jowly MacMahon was initially typed in gangster roles. After scoring a personal success as Lieutenant Monaghan in the 1949 Broadway play Detective Story, MacMahon repeated the role in the 1951 film version -- and thereafter was pigeonholed in "cop" roles. Before beginning his five-year (1958-63) tenure as Lieutenant Mike Parker on the TV series The Naked City, MacMahon had been a semi-regular on Martin Kane (1950, as the newsstand owner who stocked nothing but the sponsor's cigarette) and Make Room for Daddy (1953, as Danny Thomas' agent). His last weekly TV assignment was as Hank McClure, police contact for public relations man Craig Stevens, in the short-lived Mr. Broadway. Having been born near Norwalk, Connecticut, Horace McMahon spent his retirement years in that community with his wife, former actress Louise Campbell.

Trivia: Though born in the Midwest, character actor Harry Bellaver spent the better part of his screen career playing New York- or Brooklyn-bred cops, cabbies, doormen and petty thieves. His four-decade career began with MGM's Another Thin Man (1939), and ended when he retired after 1980's Hero at Large. An inescapable guest-star presence on 1950s and 1960s television, Harry Bellaver also played Sergeant Frank Arcaro on the weekly New York-filmed cop series The Naked City (1959-63).

Trivia: Actor William A. Post Jr. appeared in many films of the '30s, '40s, and '50s. He has also worked on Broadway and frequently appeared on daytime and nighttime television.

Trivia: An understudy to blacklisted actor Zero Mostel in Broadway's The Merchant, one might have to maintain a keen eye to spot character actor Joseph Leon in such films as Shaft (1971) and Sophie's Choice (1982). With such credit listings as Cab Driver #2 and Stamp Store Proprietor, as well as voiceover credits in numerous television commercials, Leon's face may not have etched itself into one's memory, but the feeling of "seen him somewhere before" is unavoidable. Born in 1918, in New York, NY, Leon appeared in features before moving to Broadway to understudy Mostel (taking over for the actor after his death) and appear in numerous New York productions, including Glengarry Glen Ross and Café Crown. Beginning a six-year tenure as a drama professor at Hofstra University in 1966, Leon shared his skills with students while frequently appearing on TV, stage, and in film. Joseph Leon died of natural causes in Bradenton, FL, in March 2001. He was 82.
