If there is a thriller which is poignant then Blood Diamond ranks first. Leonardo DiCaprio portrays Dannie Archer, a diamond smuggler who hops all over Africa smuggling diamonds. The movie is based on the illicit diamond trade which fuels war, kidnaps children and finally ravages Africa. The film shows how racism, poverty and crime still play a major role in war-torn African countries. It captures the savagery, greed, anguish and hope of mankind.
