Cause: Sudan, specifically Darfur
The Hotel Rwanda star has, for years, been associated with the Enough Project, which works to raise awarenesss of crimes against humanity, particularly in Sudan's Darfur region. Cheadle toured Darfur with the group in 2005 and said the experience made it impossible to return to "my comfortable life and take stock in all the privileges ... and do nothing." In 2007, Cheadle co-wrote the book Not On Our Watch: The Mission to End Genocide in Darfur and Beyond with Enough founder John Prendergast. Along with Clooney, Cheadle was an outspoken advocate for South Sudanese independence.
