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 daughter of actors Gene and Kathleen Lockhart, June Lockhart made her own acting bow at age 8. In 1938, the 12-year-old June appeared in her first film, A Christmas Carol (1938), in which her parents portrayed Mr. and Mrs. Bob Cratchit. Few of her ingenue roles of the 1940s were memorable, though Lockhart did get to play the title character in The She-Wolf of London (1945) (never mind that she turned out not to be a she-wolf by fadeout time). In 1958, Lockhart took over from a recalcitrant Cloris Leachman in the role of rural wife and mother Ruth Martin on the long-running TV series Lassie. Though she professed to despise the role, Lockhart remained with the series until 1964, and over 20 years later satirically reprised the character on an episode of It's Garry Shandling's Show. She went on to play the young matriarch of the "space family Robinson" on the Irwin Allen TV endeavor Lost in Space (1965-68), and portrayed a lady doctor on the last two seasons of the bucolic sitcom Petticoat Junction. In deliberate contrast to her TV image, Lockhart enjoyed a bohemian, kick-up-your-heels offscreen existence. At one juncture, she was fired from her co-hosting chores at the Miss USA pageant when it was revealed that (gasp!) she was living with a man much younger than herself. June Lockhart is the mother of Anne Lockhart, a prolific TV actress in her own right.

Trivia: Supporting actor Kent McCord is best known for co-starring in the long-running series Adam-12 (1968-1975). McCord made his film debut in the made-for-television movie The Outsider (1967). Following the demise of Adam-12, McCord continued appearing in TV films and in low-budget features such as Unsub (1985) and Return of the Living Dead 3 (1993).

Trivia: Before becoming a character actor, John Steadman spent 30 years in radio as a producer, writer, and announcer. He began appearing in films and on television in the early '70s, and was frequently typecast as a crusty old codger.
