Zwick’s 2006 thriller is a compelling and jarring look at the illegal diamond trade within civil war Sierra Leone. A fisherman and a smuggler unite to recover a priceless diamond and escape war-torn Africa.

The pace is tense as the pair often narrowly escape confrontation with military and rebel fighters, featuring explosive action scenes. The African-inspired soundtrack is moving and resonant.

DiCaprio and Hounsou give strong performances, both tortured men dreaming of a better life.

The film makes a powerful statement of the cost of conflict diamonds, and the horrifying impact of civil war on child soldiers and civilians.
