Netflix's most expensive TV series 'The Crown' premieres Nov. 4

Director Stephen Daldry has admitted that the Netflix's "The Crown" production has spent £200,000 (AU$ 321,000) for a moving train scene that lasts about 30 seconds.

“When we were in post production of the first episode I said ‘we really need the train, I want the train to Sandringham." Daldry told Mirror "Can we have a train? Now the train is going to cost 200k, it is an expensive train. But they sort of go ‘you can have the train.'”

Netflix is believed to have spent more than £100 million (AU$160.4 million) on the 10-episode biopic drama. "The Crown is produced to a scale that I don't think many networks could step up to," Ted Sarandos, Chief Content Officer of Netflix, told Variety. "Because our audience is large and global and the story is incredibly local we can invest heavily in a project like that."

Sarandos said that the budget for the biopic drama was cost-effective because viewers preferred an original versus a recycled content. “We’re investing in film so that we can more aggressively give the consumers what they are telling us they want." Sarandos spoke at a question-and-answer session at the Royal Television Society Conference.

Inspired by true events, "The Crown" tells the story on the coronation and life of Queen Elizabeth. It can run for six seasons that covers each decade of the Queen's reign. But as of this moment, Netflix has only ordered two seasons.

The first season begins in 1947 with King George VI (Jared Harris) coughing up blood into a lavatory bowl as the opening scene. It also features Queen Elizabeth’s (Claire Foy) wedding, the Queen's relationship with Winston Churchill (John Lithgow) as her prime minister and the sleeping habit of Prince Phillip (Matt Smith). “A crucial thing is that Philip sleeps naked. That’s a fact. That was something that we found out,” Foy revealed at a Netflix event in New York (via Radio Times).

"I was really struck by the relationship between Winston Churchill, this old, frightened fading lion, and this beautiful young girl who had become queen much earlier than she hoped," Peter Morgan, "The Crown" writer, told The New York Times last year. "I thought, this could be a film, and I started writing it with that intention. Then I began to think, shouldn't the story start earlier, with her wedding to Philip, and then realized: There might be a TV show in this."

The season premieres on Netflix on Nov. 4
