I didn't mean to make you feel challenged. You don't have to defend your usages. Especially not if you didn't write hastily. But it is a matter of style and taste, not strict correctness. I still think your uses of "debutantes," "a taste for brown," "Casanova," and "floozie" not to mention the rarely used "predacious" are all distracting, and not in a good way; and references to dictionary or online encyclopedia don't make them more palatable or justifiable. I didn't go by the boys using the word "brothers" but by their closeness, their living in the same house in the story, their physical similarity and their having the same last name. When I said Clark's "oeuvre" I meant as I think was clear, his work as a still photographer and publisher of his books, above all, not just his other movies.
I haven't read a review that properly sets the film within Clark's ouvre as you wish.
You have now. I just wrote one. But actually I think others have done that too, to some extent anyway. It just isn't done enough, and the awareness of Clarrk as a still photographer, which in the whole scheme of things is likely to be his main claim to fame, still seems to be largely lacking on the part of film writers.
