I haven't seen the film yet, but looking for it came across the homepage of the Knud Rasmussen Society. Knud Rasmussen was a (famous, in Denmark at least)explorer in Greenland, who was the man behind the film, but died before the film was shown.
Knud Rasmussen was born in Greenland, led several expeditions in Greenland, left a host of blue eyed babies all over Greenland and was mourned all over Denmark when he died in 1935.
The film is introduced by the Danish Prime minister at the time.
The museum sells the film on DVD, it costs around 30 Euro.
The easiest way is probably to mail the Museum as all information on their homepage is in Danish. The museum can easily be found by searching for Knud Rasmussen House in DenmarK
