PARK CITY - Even with four critics reviewing movies it's hard to catch everything at a festival as big as Sundance. One movie that we'll be reviewing over the next few days is Edet Belzberg's new documentary "Watchers of the Sky."  The film debuted last weekend in the U.S. documentary competition and follows four modern day humanitarians who all owe something to the legendary Raphael Lemkin, the man who first termed the word genocide (and that was just the beginning of his legacy).

In an exclusive clip provided to HitFix, U.S. Ambassador Samantha Power talks about how Lemkin came up with the word and why it was so necessary.  You can watch the clip embedded at the top of this post.  

Look or a review of "Watchers" later this week on HitFix.
