A new film biography of Burmese democracy leader Aung San Suu Kyi had its world premiere Monday at the Toronto Film Festival.

The film, called The Lady, was directed by noted French action director Luc Besson. It focuses on Aung San Suu Kyi's relationship with her British-born husband Michael Aris after she returned to Burma in 1988 to care for her ailing mother.

Aung San Suu Kyi went on to lead Burma's pro-democracy movement, culminating in her National League for Democracy winning elections in 1990. The ruling military junta refused to acknowledge the results, and Aung San Suu Kyi was subjected to long years of detention.

Aris died of prostate cancer in 1999 without ever seeing his wife again.

The Lady was filmed largely in Thailand and Burma.

Malaysian actress Michelle Yeoh, who won fame as a Chinese spy in the 1997 James Bond film Tomorrow Never Dies, portrays the Nobel Peace Prize winner, while British actor David Thewlis plays Aris.

Yeoh traveled to Burma to visit Aung San Suu Kyi following her release from seven years of house arrest in November 2010. But Yeoh was deported when she tried to return to Burma earlier this year.
