Ryan Coogler, the director of "Black Panther," shared an emotional letter thanking fans for their support of his movie. In addition to breaking records, "Black Panther" inspired a pop culture phenomenon. "Never in a million years did we imagine that you all would come out this strong," Coogler wrote. "Deep down we all hoped that people would come to see a film about a fictional country on the continent of Africa, made up of a cast of people of African descent," Coogler wrote.
