Squid Game director Hwang Dong-hyuk has explained why Seong Gi-Hun dyed his hair red.
The South Korean Netflix series - for those unaware - follows 456 Squid Game players who are in major financial ruin, battling it out for a hefty cash prize of 45.6 billion won - around £23.2 million.
The contestants compete against one other in a selection of deadly children's games and everyone, apart from the winner, dies.

It's quite literally survival of the fittest, and there's no room for error.
Now, at the very end of the show, main character Seong Gi-Hun (played by Lee Jung-jae) heads on into a hairdressers where he decides to have his entire head of hair dyed red.
This created a fair amount of confusion among those who had watched the show.

One tweeted: "Finished Squid Game. Not sure how I feel about the ending. Also super confused why the main character decided to dye his hair red at the end."
Another said: "Okay I finished Squid Game so I'm asking what we all need to know: Why. Did. He. Dye. His. Hair. That was an even bigger crime than...[no spoilers]."
Earlier today (1 February) Netflix gave us a first-look at season two, and the main character still has his red hair.

He said: "I thought about this intuitively.
"Thinking about how Gi-Hun should change his hair in a hair salon. I imagined being him and thought to myself, 'what is the colour that you would never choose to dye your hair?'
"Then I came to the conclusion that Gi-Hun would never dye his hair red. It would be the craziest thing for him to do. So I chose the colour and I thought it really showed his inner anger."
This comes after Netflix's announcement in December that it's casting a new bunch of contestants for season two of Squid Game: The Challenge.

The 10-part reality series recreates the outfits and sets, although the deadly consequences from the individual games are replaced with an elimination-style competition.
With a prize pot of $4.56 million (about £3.6 million) up for grabs for the last player standing, it's sure to be a lucrative opportunity, but you've got to make it through to the end.
This is easier said than done.
