But when a film takes lots and lots of shots and motifs from one single other film, there's a point at which it stops being a homage and becomes plagiarism.
It's been years since I've seen either of these films - although I remember Perfect Blue having a huge impact on me around age 20 - so I don't have an opinion on whether plagiarism happened here or not. Certainly the author of this article wants us to believe it did but I didn't find the article convincing one way or another.
I also wonder how common it is, and what's considered to be an acceptable level in the film industry - are there hard and fast rules about what constitutes plagiarism, like there is in academic writing? Or is there an acceptable level in the US that's different to Japan, perhaps?
Or more simply, suing cross-countries in such a complicated field as copyright, is extremely hard. In many cases, tbf, this goes both ways - which is why the US is always very keen to "harmonize" copyright laws whenever they are discussing trade deals. But the imbalance in economic resources typically means richer players in the US have a degree of recourse that non-US players will almost never get.
Imbalance between the US and Japan? Remember this happened in the year 2000. Look up which of the two countries had higher per capita GDP back then.
In any case, it doesn't seem like anyone is suggesting this was plagiarism at a level that could be sued over - it's not a case like The Good, The Bad, and The Ugly which was a shot for shot copy. I was more thinking about ideas of honor in Japan vs the US and how that might affect the respective outlook of the two directors.

I don't think there is any particular stigma with the concept of suing for plagiarism in Japan, or any higher tolerance for copying, at least since the '90s (in the '80s and earlier, their mindset was definitely different - more similar to modern Chinese attitudes for which ripping off is just a fact of life; but newer generations are less hungry and hence less unscrupolous).
