Trivia: American actor Hugh O'Brian accrued his interest in acting while dancing with movie starlets at the Hollywood Canteen during his wartime Marine days. O'Brian attended the University of Cincinnati briefly, and later supported himself selling menswear door-to-door. He made his first film, Never Fear, in 1950, working but sporadically during the next five years; what few acting parts he received were on the basis of his broad shoulders and six-foot height. In one film, Fireman Save My Child (1954), O'Brian was cast because he and costar Buddy Hackett physically matched the previously filmed long shots of Fireman's original stars, Abbott and Costello. Answering a cattle-call tryout for the new ABC TV western Wyatt Earp in 1955, O'Brian was almost instantly chosen for the leading role by author Stuart Lake, who'd known the real Wyatt and had been his biographer for many years (reportedly Earp's widow also okayed O'Brien after a single glance). O'Brian became a major TV star thanks to Wyatt Earp, which ran for 249 episodes until 1961. The series was not only tough on the actor but on his fans; reportedly there was a sharp increase in gun accidents during Wyatt Earp's run, due to young would-be Earps who were trying to emulate Wyatt's fast draw (this despite the fact that the TV Earp, like the real one, used his firearms only when absolutely necessary). Like most western TV stars, O'Brian swore he was through with shoot-em-ups when Earp ceased production, and throughout the '60s he worked in almost every type of film and theatrical genre but westerns. He showed considerable skill in the realm of musical comedy, and became a top draw in the summer-stock and dinner theatre circuit. In 1972, O'Brian starred in the computer-happy secret-agent TV series Search, which lasted only a single season. As he became the focus of hero worship from grown-up Baby Boomers, O'Brian relaxed his resistance toward Wyatt Earp and began showing up on live and televised western retrospectives. The actor reprised the Earp role in two 1989 episodes of the latter-day TV western Paradise, opposite Gene Barry in his old TV role of Bat Masterson. He was Earp again in the 1991 TV movie The Gambler Returns: The Luck of the Draw, in which he managed to shine in the company of several other cowboy-show veterans (including Barry, again) and was permitted to walk into the sunset as an offscreen chorus warbled the Wyatt Earp theme music! Hugh O'Brian's most recent turn at Ol' Wyatt was in a hastily assembled CBS movie mostly comprised of clips from the old Earp series, and released to capitalize on Kevin Costner's big-budget Wyatt Earp film of 1994. O'Brian died in 2016, at age 91.

Trivia: Had he been born a decade earlier, American actor Denver Pyle might well have joined the ranks of western-movie comedy sidekicks. Instead, Pyle, a Colorado farm boy, opted for studying law, working his way through school by playing drums in a dance band. Suddenly one day, Pyle became disenchanted with law and returned to his family farm, with nary an idea what he wanted to do with his life. Working in the oil fields of Oklahoma, he moved on to the shrimp boats of Galveston, Texas. A short stint as a page at NBC radio studios in 1940 didn't immediately lead to a showbiz career, as it has for so many others; instead, Pyle was inspired to perform by a mute oilfield coworker who was able to convey his thought with body language. Studying under such masters as Michael Chekhov and Maria Ouspenskaya, Pyle was able to achieve small movie and TV roles. He worked frequently on the western series of Roy Rogers and Gene Autry; not yet bearded and grizzled, Pyle was often seen as deputies, farmers and cattle rustlers. When his hair turned prematurely grey in his early '30s, Pyle graduated to banker, sheriff and judge roles in theatrical westerns -- though never of the comic variety. He also was a regular on two TV series, Code 3 (1956) and Tammy (1966). But his real breakthrough role didn't happen until 1967, when Pyle was cast as the taciturn sheriff in Bonnie and Clyde who is kidnapped and humilated by the robbers -- and then shows up at the end of the film to supervise the bloody machine-gun deaths of B&C. This virtually nonspeaking role won worldwide fame for Pyle, as well as verbal and physical assalts from the LA hippie community who regarded Bonnie and Clyde as folk heroes! From this point forward, Denver Pyle's billing, roles and salary were vastly improved -- and his screen image was softened and humanized by a full, bushy beard. Returning to TV, Pyle played the star's father on The Doris Day Show (1968-73); was Mad Jack, the costar/narrator of Life and Times of Grizzly Adams (1978-80); and best of all, spent six years (1979-85) as Uncle Jesse Duke on The Dukes of Hazzard. Looking stockier but otherwise unchanged, Denver Pyle was briefly seen in the 1994 hit Maverick, playing an elegantly dishonest cardshark who jauntily doffs his hat as he's dumped off of a riverboat. Pyle died of lung cancer at Burbank's Providence St. Joseph Medical Center at age 77.
