10 Genius Movie Moments When Unreliable Narrators Changed EVERYTHING

There are numerous different reasons as to how and why a narrator can be unreliable. Some on this list looked to hide something that they had done, or some incriminating part of the story, while others didn't even know they were unreliable at all.

However, Teddy Daniels (Leonardo DiCaprio) had one of the more complex points of view for his own life and the story told in Martin Scorsese's Shutter Island. Daniels was a US Marshall brought to Shutter Island to investigate a patient gone missing, before being convinced that there was a conspiracy at the correctional facility for the criminally insane and that he wouldn't be able to leave.

But Teddy Daniels, who believed he was there to look for Andrew Laeddis, his wife's killer, didn't exist. Daniels was an alter-ego with a mission on the island Laeddis had created to get away from the fact that he killed his wife after she had drowned their three children.

Dr. Cawley (Ben Kingsley) allowed Laeddis to play out the fantasy he had been telling himself for two years as part of an attempted role-playing therapy, before explaining everything to him in the lighthouse on the island. When Cawley began to talk through the facts, it didn't make sense at first, not truly. Not until he began calling Teddy Daniels by Andrew did jaws hit the floor and things start to fall into place.
