Rejected For A Decade
The script took a year to write and was finished by 2009, however it was rejected many times over the next 10 years. It was finally picked up by Netflix in 2019, which ended up being an amazing decision by the company given the massive success of the show.
Too Violent For Commercial TV
Hwang Dong-hyuk believes that the show was not a great fit for commercial TV. He said: “At the time, it seemed very unfamiliar and violent. There were people who thought it was a little too complex and not commercial.” He abandoned pushing the show until Netflix called him in 2019.
