Man shares all hidden clues people missed throughout Shutter Island that hint to major twist ending

A TikTok user has revealed yet more blink and you'll miss it moments from Martin Scorsese's neo-noir film Shutter Island.

The thriller is one of those movies were every rewatch you have you wondering how you didn't see the infamous twist coming.

Spoilers below of course.

Starring Leonardo DiCaprio, Mark Ruffalo, Ben Kingsley, and Michelle Williams, Shutter Island follows the story of Teddy Daniels (DiCaprio), US Marshall with a fear of water who's been sent to investigate the disappearance of a patient housed at a psychiatric hospital on a small, inhospitable island.

However, nothing can quite prepare you for the revelation that Teddy is actually a man named Andrew Laeddis, a man who murdered his wife after discovering that she'd drowned their three children.

The whole plot of the film is then revealed to be an attempt to get Andrew to remember why he's in the hospital, with his 'partner' Chuck Aule (Ruffalo) revealed to be his primary doctor.

The reveal of Teddy's true identity is completely mind-blowing the first time you watch the film, until you begin rewatching and realise that Martin Scorsese had been dropping hints to us the whole time.

So what are the hints thrown our way?

You may have already spotted more obvious clues such as the fact that Teddy doesn't his own lighter, the behaviour of the guards and Chuck's inexperience with a gun — but this content creator wants you to pay very close attention to the use of water in the film.

Explaining his observations in a TikTok, a film analyst who goes by the username @longmirelp, explained that Teddy has a hatred of water due to his children's demise. "When the movie opens up he's on a boat and he's throwing up, you assume it's due to seasickness," he explained. "But there are clues throughout the movie suggesting it's not the rocking of the boat, it's the literal sight of water that's making him sick."

The creator also points out how a glass of water a patient is drinking vanishes in Teddy's POV, suggesting he refuses to see it.

Water is then referenced multiple times in a scene with Kingsley's Dr. John Cawley as they try to get Teddy to remember his true identity.

Scorsese also utilises the weather to hint at Teddy's refusal to acknowledge the truth, as the majority of the film is set during a rainstorm.

That's right, pathetic fallacy actually exists outside of our GCSE English lessons in school.

"Water represents the truth, but he doesn't want to see the truth," the creator adds, noting that the rain ceases once Teddy accepts that he is Andrew.

"The rain from the angry storm is the truth of what happened to his kids trying to slip back into his consciousness."

Martin Scorsese, take a bow.
