You absolutely, positively MUST see this movie. Merion C. Cooper, director of the original (1930's) King Kong & two other Americans filmed this incredible exodus in 1927. With heavy, old camera equipment. In the winter. In the mountains of Iran. By foot and mule. And their subjects are utterly awe inspiring.I first saw this silent, B&W documentary in 2005. I was right in the middle of packing for a huge, draining household move from the mountains of New Mexico to Texas. My husband was sick, I was utterly exhausted, and I was just 3 days out from the moving company's arrival. I sat down at midnight & caught this on TCM (Turner Classic Movies) and was so inspired I promised to never complain about modern moving again (and I haven't)!These Iranian tribesman undertake an annual pilgrimage across the most challenging terrain you would ever believe humans could traverse JUST TO GET THEIR ANIMALS TO GRASS. They walk barefoot through the snow. Herding cattle and sheep and horses. With cradles on their backs. And dogs tied to the tops of the animals. They cross freezing meltwaters on inflatable goatskins.If I hadn't seen it myself, I wouldn't believe it. Anyone with a sense of adventure has got to see this one!!!
