I watched this film on TV about 10 years or so. Definitely not a Japanese movie but it’s Asian, possibly Vietnamese. I’m only saying this because i think it takes place after the war and it’s about a gang. i only remember two scenes:

1. One guy slits another guy’s throat on top of a building because he raped or beaten a girl or a young woman. There’s barely any dialog.

2. One guy is at home alone and puts blue ink in his mouth. I’m not sure he drinks it though. In the same scene he also puts a small fish in his mouth.

The movie is in colour. That’s it.

this movie is american. is about two teenagers that are best friends and one of them dies early on in the film. the surviving friend and his mother are crying and hugging and next thing you know they become lovers. he remains hidden in her attic and her husband doesn’t knows about anything.
