Django Unchained
The titular character in Django has a pretty unique look, which includes his signature aviator sunglasses. Unfortunately, this particular accessory is a bit out of place. Sunglasses weren't popular in the U.S. until 1929 and were often only worn for medical purposes.
Malcolm X
When the firebombings begin on Malcolm's home, he yells for someone to call 911, but his request is a little early. Malcolm X was murdered in 1971—three years before the 911 service existed.
