These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Brilliance: Joseph running a gigantic con on the Russian hunter was about the only way of showing a traditional (i.e. racist) Western genre depiction of Native Americans in modern times without grossly offending people. It served both as a subversive Take That to the genre and a loving homage / way of Getting Crap Past the Radar all in one.
They Just Didn't Care: The credits for every episode of Bret Maverick call it "A Comanche Production in association with Warner Bros. Television"... but James Garner's company (which produced most of his post-Maverick projects) is Cherokee Productions. The book Maverick: Legend Of The West confirms the wrong American Indian tribe was used.
