Character mistake: Ben Kingsley is Dr. John Cawley. But he is called Steven when the doctors are grouped together discussing how to handle the patients due to the hurricane, right after the graveyard scene.

Continuity mistake: When Teddy's kids are lying dead on the grass, the position of the girl's arms keeps changing between shots.
George Noyce: Don't you get it? You're a rat in a maze.
Trivia: During the ferry approach at the start, we are shown Shutter Island. In actuality this is a combination of Peddocks Island (the decaying brick buildings), Maine's Acadia National Park, Massachusetts' Medfield State Hospital, and Turner Hill Country Club's Rice Estate (located in Ipswich, MA), which were combined via CGI. Additionally, the mountainous region of the island (shown as the ferry approaches) was also CGI, and added in post-production.
Question: The children in Teddy's hallucinations were bloody but they died by drowning. Is this just an inference to Andrew's guilt that his children's "blood is on his hands" because he didn't seek treatment for Dolores' mental illness? Or is it Scorsese being overly dramatic and adding a lot of blood where it doesn't belong? Also, how exactly did Andrew kill Dolores? Did he use his service revolver, even though we don't hear the shot?





Chosen answer: I think the recurring blood comes from the blood of his wife when he killed her. there was a lot of blood you see, in his psychosis that means a lot and has taken over a large part of his hallucinations, just like Dachau camp. Yes, he did shoot his wife Dolores, in the belly. You can see it in the end of the movie.
