Premiering September 12, 1959, on NBC, Bonanza was television’s first full hour western series filmed in color. For a prime time sagebrush saga, it is second only to Gunsmoke, running a staggering 14 seasons into 1973 and producing a grand total of 431 episodes.

Facing possible cancellation after its first season — the writing was clichéd and the characters were not always delineated sympathetically— Bonanza was saved by network executives keen on promoting new RCA color television sets to an audience still satisfied with black and white sets. And full disclosure — RCA was NBC’s corporate parent.

Lorne’s constant line is (Landon adopts a mockingly serious tone), ‘If we’re not back in five minutes, kill him.’

“And Dan Blocker, every time a girl would get off a stage, Dan would go (Landon makes a goofy swooning face). I was jumping around with an umbrella stabbing people in the stomach.

“We sat and watched this, all the guys that had worked together for so many years, and just yucked for one hour. Actually at the time we filmed the pilot we thought it was rotten. We were very lucky that the show got on because the pilot was not a particularly good pilot. Once it got on, things started to gel…”

Bonanza’s premise finds a three-time widower, Ben Cartwright — portrayed by Canadian actor Lorne Greene — one of the largest landowners in Nevada. Nicknaming…
