Jude Law paid a visit to war torn Afghanistan to promote Peace Day - an annual day urging global cease fire and nonviolence on September 21st, USA Today reports.

"It seemed that they really want to make this day, the Peace Day, work. And they did," Jude tells reporters.

"People recognize the day, because they recognize that lives could be saved." Law is in Afghanistan with director Jeremy Gilley to help produce a documentary film, called The Day After Peace.

The United Nations General Assembly adopted Peace Day in 2001, following a lobbying campaign by Gilley. Law and Gilley started filming their documentary in Afghanistan last year.

Law said the documentary, which also features Angelina Jolie, the Dalai Lama, and Annie Lennox, is the most important film he has been apart of. On his experiences in Afghanistan, Law tells reporters, "When I left Kabul last year, I was hugely moved not by the conflict that I have read so much about, but by the people's courage and the people's sense of hope."

Law and Gilley, who arrived in Kabul on Sunday, are to meet President Hamid Karzai, top NATO and U.N. officials, and members of the aid community.
