Squid Game may have quickly become Netflix's most successful show ever, but its creator has said he hasn't quite made his fortune from the massive hit.

Speaking to The Guardian, Hwang Dong-hyuk has revealed that he hasn’t quite matched the €33 million prize up for grabs on the South Korean show, which sees a group of desperate people locked in a battle royal to claim the cash.

"I’m not that rich. But I do have enough," the 50-year-old writer said. "I have enough to put food on the table. And it’s not like Netflix is paying me a bonus. Netflix paid me according to the original contract."

He added that working on the show was "draining" and so stressful that he lost six teeth.

"It was physically, mentally and emotionally draining. I kept having new ideas and revising the episodes as we were filming so the amount of work multiplied." he said.

Netflix claims that Squid Game has been watched by 142 million households and added 4.4 million subscribers to the platform.

Hwang says the nine-part show was inspired by his own personal experiences in the wake of the global financial crash 13 years ago.

"I was very financially straitened because my mother retired from the company she was working for. There was a film I was working on, but we failed to get finance," he said.

"So, I couldn’t work for about a year. We had to take out loans - my mother, myself and my grandmother."

Hwang also said that comic books helped him to create the hit show.

"I read Battle Royal and Liar Game and other survival game comics. I related to the people in them, who were desperate for money and success. That was a low point in my life.

"If there was a survival game like these in reality, I wondered, would I join it to make money for my family? I realised that, since I was a film-maker, I could put my own touch to these kinds of stories, so I started on the script."

The ultra-violent show has been praised for its anti-capitalism message, but Hwang said it was "not profound", adding that the issues of economic inequality portrayed were more to do with the pandemic.

"During the pandemic, poorer countries can't get their people vaccinated," he said. "They’re contracting viruses on the streets and even dying. So, I did try to convey a message about modern capitalism. As I said, it’s not profound."
