Formosa Betrayed is a 2009 American political thriller film directed by Adam Kane, written by Charlie Stratton, Yann Samuell, Brian Askew, Nathaniel Goodman, with story by Will Tiao and Katie Swain, and starring James Van Der Beek. Set in Chicago and Taiwan in the 1980s, the story follows a Federal Bureau of Investigation (FBI) agent investigating the murder of a Taiwanese professor at a midwestern college. The search for his killers takes the agent to Taiwan where he discovers there is more involved in this murder than he ever anticipated. Although Formosa Betrayed has been regarded as a "pan-green movie", its writers say they did not take sides over the Pan-Blue/Pan-Green political divide.
Formosa Betrayed opened in 15-20 cities in North America the weekend of February 28, 2010.
Inspired by two actual events, one surrounding the death of Professor Chen Wen-chen (陳文成) of Carnegie Mellon University in 1981, and the other the 1984 assassination of journalist Henry Liu in California by Chen Chi-li and his fellow Bamboo Union members, Formosa Betrayed is the story of FBI Agent Jake Kelly's (James Van Der Beek) investigation of the murder of Henry Wen (Joseph Foronda), a Taiwanese professor in Chicago. With the help of his partner Tom Braxton (John Heard) and a sharp Chicago police detective (Leslie Hope), Agent Kelly discovers that the murderers have fled to Taipei, capital of Republic of China (Taiwan).
