From 2001 to 2007, Damon gained wider international recognition as part of two major film franchises.He continued to garner praise from critics for his roles as the eponymous character in Saving Private Ryan (1998), the antihero in The Talented Mr.Ripley (1999), a fallen angel in Dogma (1999), an energy analyst in Syriana (2005), and a corrupt Irish-American police officer in The Departed (2006).
The film, and Damon's casting, were not well received by critics.
Damon is also an ambassador for ONEXONE, a nonprofit foundation committed to supporting, preserving and improving the lives of children at home in Canada, the United States, and around the world.

Damon's 2010 projects included Clint Eastwood's Hereafter and the Coen brothers' remake of the 1969 John Wayne-starring Western True Grit.
The Washington Post concluded, "Damon, constantly flashing his newscaster's teeth and flaunting a fake, 'Masterpiece Theatre' dialect, comes across like someone who got lost on the way to an audition for a high school production of The Pirates of Penzance." In 2006, Damon joined Robert De Niro in The Good Shepherd as a career CIA officer, and played an undercover mobster working for the Massachusetts State Police in Martin Scorsese's The Departed, a remake of the Hong Kong police thriller Infernal Affairs.
