The Crown is a Netflix Original series, meaning all 20 episodes are available to watch on Netflix.

"It is just inaccurate, obviously totally unfair, but also quite dangerous, in fact, to the British constitution," said historian Andrew Roberts, who wrote "The Royal House of Windsor," tracing the history of the queen's family. The show does, indeed, blend history and fiction.

"We are creating a work of fiction, albeit based in some reality. But ultimately, there's only so much research you can do," Josh O'Connor, who plays a young Prince Charles, tells me. "After a time, you just got to crack on and create something for yourself."

The first season of The Crown follows the life and reign of Queen Elizabeth II. It consists of ten episodes and was released on Netflix on 4 November 2016.
