Christine Choy and Renee Tajima’s 1987 documentary about the 1982 murder of a young Chinese-American engineer by a white autoworker, who thought the engineer was Japanese and who got off virtually scot-free, offers a fascinating and disturbing picture of overlapping concerns: racial attitudes, the auto industry, the media, Asian-Americans, and various legal issues. While the legal questions aren’t treated as thoroughly as one might like, this rapidly cut and provocative piece of investigative journalism never fails to hold interest. 87 min. (JR)
