Trivia: Intending to become a dentist like his father, American actor Edgar Buchanan wound up with grades so bad in college that he was compelled to take an "easy" course to improve his average. Buchanan chose a course in play interpretation, and after listening to a few recitations of Shakespeare he was stagestruck. After completing dental school, Buchanan plied his oral surgery skills in the summertime, devoting the fall, winter and spring months to acting in stock companies and at the Pasadena Playhouse in California. He was given a screen test by Warner Bros. studios in 1940, received several bit roles, then worked himself up to supporting parts upon transferring to Columbia Pictures. Though still comparatively youthful, Buchanan specialized in grizzled old westerners, with a propensity towards villainy or at least larceny. The actor worked at every major studio (and not a few minor ones) over the next few years, still holding onto his dentist's license just in case he needed something to fall back on. Though he preferred movie work to the hurried pace of TV filming, Buchanan was quite busy in television's first decade, costarring with William Boyd on the immensely popular Hopalong Cassidy series, then receiving a starring series of his own, Judge Roy Bean, in 1954. Buchanan became an international success in 1963 thanks to his regular role as the lovably lazy Uncle Joe Carson on the classic sitcom Petticoat Junction, which ran until 1970. After that, the actor experienced a considerably shorter run on the adventure series Cade's County, which starred Buchanan's close friend Glenn Ford. Buchanan's last movie role was in Benji (1974), which reunited him with the titular doggie star, who had first appeared as the family mutt on Petticoat Junction.

Trivia: A top athlete at Brown University, Don Haggerty performed military service and did stage work before his movie-acting debut in 1947. Free-lancing, Haggerty put in time at virtually every studio from Republic to MGM, playing roles of varying sizes in films like Sands of Iwo Jima (1949) The Asphalt Jungle (1951), Angels in the Outfield (1951) and The Narrow Margin (1952). Most often, he was cast as a big-city detective or rugged westerner. During the first (1955-56) season of TV's The Life and Legend of Wyatt Earp, Haggerty showed up semi-regularly as Marsh Murdock. Don Haggerty was the father of Grizzly Adams star Dan Haggerty.

Trivia: Pennsylvania-born actor Don Keefer enjoyed a 60-year-plus career on stage and screen that saw him range freely across character parts and leading roles in both fields. An actor from his youth, he started early playing leads, portraying the title role in The Adventures of Marco Polo for a production of the Child Study Association. He won the Clarence Derwent Award for his early work on Broadway, and spent his early career working alongside the likes of Ethel Barrymore, Helen Hayes, and José Ferrer, and under such directors as Moss Hart, Elia Kazan, and Margaret Webster (including the famed production of Othello starring Paul Robeson). Keefer was a charter member of the Actors' Studio, and originated the role of Bernard, the studious neighbor son-turned-lawyer in Arthur Miller's Death of a Salesman. He was the only actor to remain with the production for its entire Broadway run, and subsequently made his screen debut in 1951 in the movie adaptation of the play produced by Stanley Kramer and directed by Laslo Benedek. From that beginning, he went on to appear in more than 130 movie and television productions, in between theatrical work on both coasts (including a stint at the Theatre Group at UCLA under John Houseman). Highlights of his stage career include a highly acclaimed touring production of Anton Chekhov: The Human Comedy, focusing on the lighter side of Chekhov's work. On screen as on stage, Keefer played a wide variety of parts -- he made a fine villain-turned-neutral in "Winchester Quarantine," an early (and very powerful) episode of Have Gun Will Travel, but was equally good as Ensign Twitchell, the comically (yet tragically) over-eager and officious junior officer in Joseph Pevney's Away All Boats, during this same period. Don Keefer was still working in the late '90s, in movies such as Liar Liar and an episode of Profiler. But amid hundreds of portrayals, Keefer's single most memorable role for most viewers -- other than Bernard in Death of a Salesman -- is almost certainly that of Dan Hollis, the doomed neighbor whose birthday celebration comes to a hideous end (his head popping out of a giant jack-in-the-box) in the 1961 Twilight Zone show "It's a Good Life."
