Mark at Movie Masterworks has written an excellent article on Stray Dog (Nora inu). His observations on Kurosawa’s movie are well worth reading.
Before you go, however, please note that reading the essay may take roughly two hours of your time. Not because the article is so long, but because it’ll make you want to watch the film again.
Edit: As kindly pointed out by Mark below, the essay was actually not written by him, but Gary Morris at Images: a Journal of Film and Popular Culture. Nevertheless, thanks to Mark for bringing the article to my attention via his blog. 🙂
