The Stormy Filming of Oz

"The Wizard of Oz" is 70 and The Telegraph has an intriguing account of its filming :

In September 1938, the seamstresses began their work. Everything, from the felt vests, jackets, bonnets and dresses of the Munchkins to the heavy fur-covered uniforms of the Winkies (the Wicked Witch’s soldiers), was custom-made. Letters were sent to zookeepers around the United States asking for the feathers of condors, eagles and vultures, which were stitched together to make wings for the witch’s terrifying flying monkeys. Thousands of pairs of shoes and stockings were dyed green for the inhabitants of the Emerald City.
