'Wicked' Slapped With Trigger Warning by UK Film Board for Discrimination Against "Green-Skinned" People

The legend of the green children of Woolpit concerns two children of unusual skin colour who reportedly appeared in the village of Woolpit in Suffolk, England, sometime in the 12th century, perhaps during the reign of King Stephen (r. 1135–1154). The children, found to be brother and sister, were of generally normal appearance except for the green colour of their skin. They spoke in an unknown language and would eat only raw broad beans. Eventually, they learned to eat other food and lost their green colour, but the boy was sickly and died around the time of his and his sister's baptism. The girl adjusted to her new life, but she was considered to be "very wanton and impudent". After she learned to speak English, the girl explained that she and her brother had come from a land where the sun never shone, and the light was like twilight. According to one version of the story, she said that everything there was green; according to another, she said it was called Saint Martin's Land.
