Knives: I don't understand what you're trying to say about auteurship (a [presumed] preference for medium shots is an auteurist stamp?) and we seem to be talking a cross purposes here:
If he isn't the author (or co-author in his producing cases) than where does the commonalities in his work come from?
Superficiality? Coincidence? I don't know what commonalities you mean, because you haven't specified them. I don't think it serves any purpose to discuss this further unless someone really wants to try and convince me that Kramer is an auteur filmmaker, for some reason.
Here again
...more complex than the let's get to know each other and than racism will be cured easy answer of The Defiant Ones
you're asserting that the film is simplistic, ignoring all the claims I tried to make for it. But fine, I'll try with another specific example. It's not essentially Cullen and Joker getting to know each other that cuts to the heart of the racism and overcomes it. Look at the scene when the two have already begun to get to know each other, and then are about to be lynched by Mac and his mob. Joker tries to fall back on his white privilege to save his own hide but then finds that in some situations it doesn't count. Any simplistic views of a society divided along racial lines are complicated throughout the film as particular circumstances, including socioeconomic background, are brought into the equation. I don't want to be accused of reading the film strictly on ideological grounds, so I'll give another example which relates more directly to the characters' personalities: In the scene where they're waiting among all the barrels to get into the turpentine camp, Joker talks about his "dog eat dog" outlook and disavowal of cooperation.
Again, the film doesn't "solve" the problem of racism. It shows how two people are able to overcome it, but it's not just by getting to know each other. The turning point of the film, as the characters must escape from the pit, is physical, visceral, and predicated on grounds of survival rather than ideology. This in a film that knives says the director shouts things rather than showing them. So much of the film's richness is elaborated through the characters' movement through various spaces of pits, bogs of quicksand, and many other hostile and shadowy landscapes, that I can't fathom this as a film that tells rather than shows.
EDIT: to clarify who I'm replying to.
