Danny Glover mingled with activists at the World Social Forum in Porto Alegre, Brazil, talking about everything from women's rights to eliminating Third World debt and poverty.
"Even though my country, the United States, is engaged in a very intensive discussion about the possibility of war in Iraq, there are still other issues in the world that must be addressed," he said Sunday in an interview with The Associated Press.
Glover, star of the "Lethal Weapon" films, became chairman of the TransAfrica Forum in 2001, the 25-year-old advocacy group best known for protesting apartheid.
The 55-year-old actor said he plans to meet with activists representing groups trying to improve conditions for youths, women and the environment, along with artists and writers.
"I think there's a great deal we can all learn from each other," Glover said.
