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: 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: Along with Marilyn Monroe and Paul Valentine, actor Bruce Gordon was given an "Introducing" credit in the 1949 Marx Brothers opus Love Happy. The swarthy, cleft-chinned Gordon played one of the henchmen of villainess Ilona Massey (the other henchman was Raymond Burr). After spending the 1950s in "heavy" film roles, Gordon was shown in a rare heroic light as American intelligence agent Matson on the 1958 TV series Behind Closed Doors. One year later, Gordon first essayed the role with which he will forever be associated: Frank Nitti, scowling second-in-command of Al Capone (Neville Brand) on the weekly TVer The Untouchables. Thereafter, Bruce Gordon was almost invariably cast as a mobster -- though often with a morbidly humorous streak, as witness his characterization of media-savvy syndicate boss Mr. Devere on the 1966 sitcom Run, Buddy, Run.

Trivia: Actor Kenneth O'Brien appeared in films of the '70s and '80s. He also appeared in made-for-TV movies and guest starred on television series.
