THE LAST GIANTS is Daniele Grieco's first feature-length documentary. Daniele was born and raised in Cologne. His father is Italian, his mother German. After three years as reporter for West German Broadcasting (WDR) in Cologne, Daniele attended New York University and the New School of Social Research from 1995 to 1999, studying film production. Several opportunities to write and direct feature series and commercials for German television enabled him to return to Cologne, where he worked for Grundy, Vox and Kinowelt.

As a schoolboy, Daniele was mesmerized by the films of Jacques Cousteau, and the master of underwater filmmaking has remained his most significant hero.
During a surfing vacation in 2006, Daniele met Katharina Heyer quite by accident, while she was leading one of her Whale Watching Tours. That chance encounter led to the making of THE LAST GIANTS.
