John Woo's "Once a Thief" is a pretty entertaining movie which is original and clever like most other Woo films. It's mostly a suspense thief picture with lots of comedy mixed in with a romantic love-triangle and a little bit of Chow Yun-Fat/John Woo gunplay action of course. There is never any blood -let in this rather light film. I think John Woo wanted to tone down the violence and put more suspense/comedy in his well-known balance scale. It's pretty obvious when the usually trigger-happy Chow Yun Fat spares the life of a threatening gangster and kicks him out of a window instead. That might be along the "Die Hard" Hollywood terms, but for loyal Chow and Woo fans, it's very surprising. The storyline is one of Woo's most simple and innocent, but it set the film up for a couple of robberies which will grip you until the end. Leslie Cheung is dead serious and good as always, Chow Yun Fat is in his "Better Tomorrow II" mood: his lighter, more comedic mode which is somewhat more likeable. This mode is usually used for Woo's lighter, less serious films which don't need much acting. Chow's "Killer" serious mood is what made him famous for, but he doesn't suit that mood as well as this movie's character does.
