An interview with L.P. Leung about his movie   The Jade Pendant -- 唐人街 1871.  

"The Jade Pendant is a tragic love story during a period of time when Chinese Americans were despised and excluded from white society. The Massacre is a byproduct of this time period that American history has suppressed. I wanted to present an entertaining film but also expose the truth about the struggles and discrimination that Chinese Americans faced."  -- LP Leung

The move was set in 1871 in Los Angeles, starring South Korean actress Clara Lee, Taiwanese actor Godfrey Gao, American actors Russell Wong, Tsai Chin and Tzi Ma, directed by Hong Kong director Po-Chih Leong.  The Jade Pendant plays at AMC Atlantic Times Square 14 in Los Angeles, and 4Star Theatre in San Francisco, and AMC Empire 25 in New York City until November 19th:
