I was only six or seven when this creep was murdering people and even I knew who he was after they busted him.
It’s possible Kubrick placed the bear imagery in the film because it matches the story's theme of fathers murdering their wives and children. Adult male bears are known to kill bear cubs which are not their own and sometimes kill the cubs' mother in the process.
Pointing this out isn’t a case of me virtue-signalling with faux outrage over politically incorrect casting. If an actor looks the part, regardless of heritage, I say, have them play the role. It is called Acting, after all.
