Trivia: Actor/director/producer William Conrad started his professional career as a musician. After World War II service, he began building his reputation in films and on Hollywood-based radio programs. Due to his bulk and shifty-eyed appearance, he was cast in films as nasty heavies, notably in The Killers (1946) (his first film), Sorry Wrong Number (1948) and The Long Wait (1954). On radio, the versatile Conrad was a fixture on such moody anthologies as Escape and Suspense; he also worked frequently with Jack "Dragnet" Webb during this period, and as late as 1959 was ingesting the scenery in the Webb-directed film 30. Conrads most celebrated radio role was as Marshal Matt Dillon on Gunsmoke, which he played from 1952 through 1961 (the TV Gunsmoke, of course, went to James Arness, who physically matched the character that the portly Conrad had shaped aurally). In the late 1950s, Conrad went into the production end of the business at Warner Bros., keeping his hand in as a performer by providing the hilariously strident narration of the cartoon series Rocky and His Friends and its sequel The Bullwinkle Show. During the early 1960s, Conrad also directed such films as Two on a Guillotine (1964) and Brainstorm (1965). Easing back into acting in the early 1970s, Conrad enjoyed a lengthy run as the title character in the detective series Cannon (1971-76), then all too briefly starred as a more famous corpulent crime solver on the weekly Nero Wolfe. Conrad's final TV series was as one-half of Jake and the Fatman (Joe Penny was Jake), a crime show which ran from 1987 through 1991.

Trivia: Muscular leading man Ed Nelson started out as a member of quickie-filmmaker Roger Corman's stock company, appearing in such drive-in fodder as Hot Rod Girl (1956), Invasion of the Saucer Men (1957) and Cry Baby Killer. In these and other low-budgeters of the late 1950s, Nelson not only starred, but doubled on the technical crew: he was one of several production assistants portraying the title crustacean in The Attack of the Crab Monsters (1956), and designed and operated the parasite props in 1958's The Brain Eaters, which he also produced. Eventually outgrowing such things, Nelson rose to TV stardom as Dr. Michael Rossi on the prime time soap opera Peyton Place, which ran from 1964 through 1969. He later starred as Ward Fuller on The Silent Force (1970) and as Dr. Michael Wise in Doctor's Private Lives (1979). In 1969, Nelson hosted a daily, syndicated talk show, which he was ultimately forced to give up when he decided to enter politics ("conflict of interests" and "equal time" were still considerations back then). He played President Truman several times, including the 1980 TV movie Enola Gay: The Men, the Mission, the Atomic Bomb, in the 1992 Brooke Shields flick Brenda Starr and onstage in Give 'Em Hell, Harry. Nelson died in 2014 at age 85.

Trivia: Lead and second lead actor, onscreen from 1955.

Trivia: Leif Garrett began his career as a child actor, appearing in the first two Walking Tall movies as Buford Pusser's son, Mike, when he was just 12 years old. He made his television debut on the family show Three for the Road in 1975, and soon took up a recurring role on the series Family. Garrett signed a recording contract in 1976 and began performing as a pop star, instantly becoming a teen heartthrob, gracing the covers of magazines like Tiger Beat. He continued to act, however, appearing most notably in movies like Francis Ford Coppola's 1983 film The Outsiders. In his personal life, Garrett has struggled with drug and alcohol addiction, leading to a 1979 car crash in which his best friend, Roland Winkler, was partially paralyzed.
