This comedy by Peter Wang (A Great Wall), a Chinese American filmmaker and former laser scientist, concerns a Chinese American laser scientist (Marc Hayashi) in New York, divorced and with a Jewish mother, who accidentally kills his assistant in a lab experiment and finds himself, through the influence of his brother-in-law (Tony Leung), dealing in arms on the international black market. Wang himself plays a jokey and philosophical police detective who narrates the story. Shot by Ernest Dickerson, Spike Lee’s usual cinematographer, this is a nice filmgently funny in some spots and wry in othersbut not a very dynamic one. With Sally Yeh (1988). (JR)
