Watch Bombuj. Brash and opinionated, Christine Choy is a documentarian, cinematographer, professor, and quintessential New Yorker whose films and teaching have influenced a generation of artists. In 1989 she started to film the leaders of the Tiananmen Square pro-democracy protests who escaped to political exile following the June 4 massacre. Though Choy never finished that project, she now travels with the old footage to Taiwan, Maryland, and Paris in order to share it with the dissidents who have never been able to return home.
