The movie you’re mentioning (Atanarjuat) is actually Canadian Inuit and came out in 2001, the movie I’m referring to was actually called Heart of Light. It stars a guy named Rasmus Lyberth, a notable musician from Greenland that’s gained some notice in the world music scene.
There was actually a traveling Greenland film festival for a while. Since Heart of Light, a number of films have been released, with the one probably getting the most notice being a documentary about Sume, the rock band that played a major role in Greenland getting home rule in the late '70s.
