Watchers Of The Sky
"Watchers Of The Sky" Premiered at Sundance

The horror of genocide simply can't be put into words. An unspeakable act, it leaves its mark across generations, reverberating through history as a stamp of supreme evil. But can justice be found for those marked by such brutal acts of violence? One lawyer thought so and forever laid the groundwork that would allow the Nuremberg trials to happen, along with the formation of the International Criminal Court.

Oscar nominated director Edet Belzberg ("Children Underground") brings her latest documentary "Watchers Of The Sky" to the Sundance Film Festival this week, and it will shine light on lawyer Raphael Lemkin. Through reminisces and insight from Samantha Power, U.S. ambassador to the U.N.; Luis Moreno Ocampo, ICC chief prosecutor; Benjamin Ferencz, Nuremberg prosecutor; and Emmanuel Uwurukundo, U.N. refugee officer, the doc explores how Lemkin created the legal framework that enabled prosecutors to bring crimes of massacre into a courtroom, and in this clip, we get a glimpse of his vision and approach that would change everything.

"Watchers Of The Sky" continues to screen this week in Sundance. Check out the clip below. Browse through all our coverage of the 2014 Sundance Film Festival by clicking here.
