The cinematography in The Godfather: Part II

My favorite scene in movie history is Vito stalking and killing Don Fanucci. DeNiro, almost a chameleon on the rooftops while Fanucci stand out like a sore thumb in the street celebration. Fanucci tapping the lightbulb. The button hitting the floor when Fanucci opens his vest after the first shot. The music. The Final scen where Vito goes back to his family as if nothing happened instead of changing the family history
