Django wears some pretty hip sunglasses in Django Unchained, but there is one big problem. Sunglasses were not widely manufactured in the United States until 1929. The movie takes place in 1858 in the south. Before the widespread use of sunglasses, they were mostly used as medical devices. They were scarcely found for regular use. The film’s director Quentin Tarantino probably had a reason for the use of the sunglasses. In a Vanity Fair article, it was revealed the Django’s sunglasses were inspired by Charles Bronson in The White Buffalo, a western film from 1977.
