"Chuen Jik Sat Sau" (2001)
This is a great Hong Kong actioner in Chinese, Japanese, and English, is about two competing hit men, a quiet and shy professional named Ono (Takashi Sorimachi) and Lok Tok-Wah (Andy Lau), a reckless, flamboyant hit man. O has been considered the #1 assassin in the area, but Tok is more showy and even savors the attention and fear that he brings.
"In our business, you're bound to rub out someone you know."
Tok is getting tired of the crappy jobs and lower pay, that he gets while his rival, O gets more pay and easier hits, but his handlers don?t like the publicity that Tok brings with him. Interpol agent Albert Lee (Simon Yam) and his partner C7 (Teddy Lin) are after both of them.
O just wants to stay under the radar. He hires a shop girl named Chen (Kelly Lin) to clean out his apartment that he never lives at, just so he can watch her from the run-down apartment across the street where he really lives at.
Soon Tok discovers this girl and toys with her. It's hard to tell if Tok really loves this girl, or if he's just playing her to get at O.
