Sue Williams and Kathryn Dietz formed Ambrica Productions in 1986 to develop and produce documentaries of international scope and interest.

Their first project was the epic CHINA: A Century of Revolution, three two-hour films for PBS that explored the turbulent social and political history of 20th century China.

The series began with CHINA IN REVOLUTION, which covered the early years of the Chinese republic from 1911 to 1949. It continued with THE MAO YEARS, examining the tumultuous years of Mao Zedong's rule, from 1949 to 1976.

BORN UNDER THE RED FLAG completed the trilogy with an exploration of the years of reform under Deng Xiaoping, from 1976 to 1997.

All three films have been broadcast nationally on PBS to widespread critical acclaim and are in educational, home video and international distribution. They have been broadcast in over 25 countries.

The company began portrait film making in its critically acclaimed biography of ELEANOR ROOSEVELT. This 2½-hour documentary special aired as part of the PBS series American Experience in January 2000 and was one of its highest rated programs ever.

CHINA IN THE RED, a two hour special which explored the human cost of the economic reforms sweeping China today by following ten families over a four year period. It aired on the PBS series FRONTLINE in February 2003.

Ambrica's documentary TIME OF FEAR, about Japanese American internment in Arkansas during World War II, was broadcast on national PBS in May 2005.

Ambrica also produced MARY PICKFORD for American Experience, a 90- minute portrait of the life and art of the world's first super-star and one the most powerful women in Hollywood history. It was broadcast on PBS in April 2005.
