* FranchiseZombie: In the final season after Dan Blocker's death which featured only Lorne Greene and Michael Landon out of the original cast.
* GermansLoveDavidHasselhoff: ''Bonanza'' was aired in Poland during TheSixties (or was it TheSeventies?...), when people desperately craved anything other than the official propaganda. This was said to result in almost total depopulation of streets around the time of airing. And it can't be wholly dismissed as NostalgiaFilter.
** It was insanely popular in the US as well. It was in the top 10 for almost a decade and the number one show ''three years in a row''.
* SpecialEffectsFailure: There's an episode where some bandits use dynamite to blow open the safe at the bank. It looks like they just stuck a sparkler on it and rigged the door to fall down.
* ReplacementScrappy: The fourth Cartwright son, Jamie, who was adopted some time after Adam's departure.
