In the same year that she directed Victory of the Faith (1933), her first of several famous cinematic projects for the Nazi Party, German actress and filmmaker Leni Riefenstahl played a supporting role in this epic adventure, co-written and co-directed by her frequent "mountain film" collaborator Dr. Arnold Fanck. Rod La Rocque stars as Dr. Carl Lawrence, leader of a mission to Greenland to recover the lost records of the ill-fated, real-life Alfred Lothar Wegener polar expedition of 1929-30. Lawrence's party includes experienced explorer/guides, as well as an adventure-seeking financier, who is in over his head and slowly driven mad by the perils of the voyage. When Lawrence's band is trapped on an iceberg, Lawrence's wife Ellen (Riefenstahl) -- a famous female pilot fashioned after Amelia Earhart -- takes off on a rescue mission, but she crashes her aircraft upon landing and is stranded along with the others. Before total disaster claims the Lawrence party, however, native eskimos and Major Ernst Udet (playing himself) arrive via kayak to save the day. Two surviving members of the Wegener party served as advisors for this well-received Man vs. Nature treatise, filmed on location in Greenland.
