I don't know this movie's title.
I know it's an asian movie, I'm thinking Japanese (It's been a long time since I've seen this). I think it's about a hitman.
I remember there being a scene in which he prepares poison by crushing a few cigarettes into a glass of water, and letting it sit for a while.
Also, I recall another scene where he's on top of a building, teaching a woman how to shoot a sniper rifle. (but no, it's not the Professional).
Please help me find this film!
