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: George Maharis was one of seven children of Greek immigrant parents. Though he could very easily have gone into his father's restaurant business, Maharis decided to try for a singing career. When his vocal chords were injured by overuse, Maharis switched to acting, studying at the Actors' Studio and making one of his earliest appearances as a Marlon Brando parody on the 1950s TV sitcom Mr. Peepers. Maharis was very active in the off-Broadway scene, appearing in Jean Genet's Deathwatch and Edward Albee's The Zoo Story. He gained a fan following (primarily female) through his weekly appearances as handsome drifter Buzz Murdock on the TV series Route 66. He played Buzz from 1960 to 1963, leaving the series for a variety of reasons, among them artistic differences and a bout of hepatitis. His subsequent film career failed to reach the heights of his TV work, and by 1970 Maharis was back in the weekly small-screen grind in the adventure series The Most Dangerous Game. When not performing in nightclubs, summer stock or films, George Maharis spent a good portion of the 1970s and 1980s indulging in his pet hobby, impressionistic painting.

Trivia: Street-smart leading actor Harry Guardino entered films in 1952 after several years of knocking around the New York stages. The best of his early film roles was Cary Grant's comic handyman in 1958's Houseboat. Guardino worked extensively in European productions in the 1960s, playing such parts as Barabbas in 1961's King of Kings. Among Harry Guardino's many TV assignments were the title role in the 1964 New York-based series The Reporter and the "Bogart/Bond" hero on the syndicated 1971 weekly Monty Nash. He made his final film appearance in Fist of Honor (1991).

Trivia: The son of an English-immigrant clothier, Mike Kellin decided to become an actor in the second grade, after watching a school production of A Christmas Carol. The restless Kellin briefly attended three colleges before serving in the Navy in World War II. After flunking out of Yale Drama School, Kellin headed to New York, where he studied acting under Lee Strasberg, Sanford Meisner and Stella Adler. Denied leading-man assignments because of what he described as his "lived-in face," Kellin's big Broadway break came in the role of the abrasive sergeant in the 1949 Broadway comedy At War with the Army; he would reprise his role in the 1950 film version, which starred Martin and Lewis. Kellin went on to win the Tony award for his performance in the 1956 Rodgers and Hammerstein musical Pipe Dream. In 1960, Kellin was cast as slovenly Chief Mate McCarthy in The Wackiest Ship in the Army; when this film was adapted into a TV series in 1965, Kellin came along for the ride in substantially the same role, though the character was rechristened as Chief Petty Officer Willie Miller. Mike Kellin's most celebrated movie appearance was his Oscar-nominated role as the father of the imprisoned protagonist in Midnight Express (1978).
