The Snow in the Poppy Scene Was Asbestos
Everyone loves the wintry sight of a field full of … asbestos?
To create snow for the poppy scene, asbestos was used. Despite the health risks having been known for years by then, it was common in the movie industry at the time.
That’s not the only asbestos in the movie—it filled the Scarecrow’s costume, and the Wicked Witch’s broom was partially made from asbestos.
