HBO's popular fantasy series has been criticized for being 'too white.'

First, it was David Oyelowo, who insists that even though a person of colour has a minor role it doesn't mean they can't have prominent story lines.

Recently, John Boyega, the first black lead in the "Star Wars" franchise, said he wasn't paying money to always see one type of person on "Game of Thrones."

"Even if you're a racist, you have to live with that. We can ruffle up some feathers,” he said.

In defence, the author and creator of the franchise, George R R Martin, explained that Westeros around 300 AC was nowhere near as diverse as 21st century America.

Game of Thrones' is set in the medieval era of Europe and that period based on location, it was not as diversified as modern Europe.
