Sieva Diamantakos was born in Rome and grew up in a coastal village near Genoa (Liguria). He began making films during his studies at the University of Bologna.

His major was film criticism with an essay on the hero's journey in the two choral films "Short Cuts" by Robert Altman and "Magnolia" by Paul Thomas Anderson. After moving to Genoa, he became a member of the electronic band port-royal and was the group's official video maker and VJ.

Inspired by the group's tours of Eastern Europe, he moved to Berlin and found a way to work between the German capital and Kyiv. There he shot his first film "Postcards from Ukraine" about the beginning of the crisis between Ukraine and Russia.

His second film "Peilhorn - Dein Drama in V Akten" about an illegal club in the German capital was produced entirely by himself and recently released on youtube. "And They Will Talk About Us" is his third film as a director.

Sieva's films always have a social approach, in which political and economic dynamics play the most important role. From there, the works expand and touch on the existential level. The direction is minimalist in terms of the means used, but often poetic. The texts alternate between tragic moments and others with lighter tones.
