Oliver Stone has never been known to shy away from controversial subjects (so much so that we guarantee that past sentence has been used, oh, about a billion times to open a piece about Stone). This weekend, his new documentary, 'South of the Border,' debuts in theaters. The documentary explores the relationship between the United States and South America -- Stone interviews seven leaders in the region -- and criticizes the roles of the U.S. government and the American media in how the governments of South America are represented. We spoke to the two-time Academy Award winner for Best Director about his new documentary and how directing 'W.' gave him a better understanding of foreign affairs. We also asked him about 'Wall Street: Money Never Sleeps' star Shia LaBeouf and the controversial comments LaBeouf made about 'Transformers 2' and 'Indiana Jones 4' at Cannes.
