Dr. Cawley reveals the entire ruse, and that Teddy is Andrew Laeddis. After Teddy finally makes his way into the lighthouse, he finds Dr. Cawley waiting for him. Dr. Cawley reveals that the past few days have been part of an elaborate and experimental ruse, orchestrated by him in an effort to get Teddy to accept the truth: Teddy is Andrew Laeddis. The plot twist is that Andrew is a patient at the facility who created Teddy as a persona used to escape the shame and trauma of killing his wife after she murdered their 3 kids.^{[1]

- Chuck walks in, revealing himself to be Dr. Sheehan, Andrew’s primary psychiatrist for the past 2 years.
- Although dubious at first, Andrew has flashbacks to the day he found his children deceased and murdered his wife and ultimately accepts what Dr. Cawley says to be true.
- Andrew is forced to voice his understanding of the situation out loud in front of the other doctor and the warden, who were ready to lobotomize him if this experimental treatment didn’t help merge his identities and rid him of his violent streak.

Andrew appears to regress mentally and walks away with the hospital staff. After some time has passed, we see Andrew smoking on some steps. When Dr. Sheehan joins him, Andrew says to him, “We gotta get off this rock, Chuck. Whatever’s happening here isn’t good.” Dr. Sheehan takes this exchange to mean that Andrew has regressed back into his Teddy persona, and shakes his head while making eye contact with Dr. Cawley across the lawn, signaling to him that their treatment had failed.^{[2]

- However, a moment after, Andrew turns to Dr. Sheehan and says, “This place makes me wonder which would be worse: to live as a monster or to die as a good man?”
  - Many view this as a symbolic line, implying that the treatment had worked but that Andrew had chosen a lobotomy over remembering his past.
- We see hospital staff begin walking toward Andrew, with one nurse concealing a large needle, presumably for surgical purposes.
- Andrew stands up and willingly goes with the hospital staff, leaving viewers to assume that he proceeded to be lobotomized.

Interpretation of Shutter Island Ending

1
Andrew pretends to regress to avoid the pain of remembering what he had done. After Andrew calls Dr. Sheehan “Chuck,” Sheehan takes this to mean that the experiment failed, and that the Teddy persona has taken over again. However, Andrew’s final question about whether it's worse to live as a monster or die as a good man to Sheehan suggests the opposite to be true.
- The most popular interpretation of the final scene is that the experiment had indeed worked and “cured” Andrew.
- However, once he remembered all the traumatic events of his past, mainly finding that his wife had murdered his 3 children and killing her himself, he decided that it was better to forget.
  - Metaphorically, Andrew might have chosen to “die as a good man” by agreeing to a lobotomy instead of living “as a monster” with the guilt and pain of his memories.
2
Andrew truly regresses into his fragmented Teddy identity. During the plot twist reveal scene in the lighthouse, Dr. Cawley tells Andrew that this is the second time they’ve attempted this treatment and that it worked once before, but that he ultimately slipped back into the Teddy delusion. While the alternate explanation is a fan favorite, it’s still totally possible that Andrew did regress into his Teddy persona.^{[3]

- He could have had no idea that he was about to be lobotomized and was just trying to appear cooperative with the hospital staff.
- Author Dennis Lehane agrees with this interpretation of the film, stating, “I would say that line, which comes across as a question—[Andrew] asks it sort of rhetorically. Personally, I think he has a momentary flash. To me, that’s all it is. It’s just one moment of sanity mixed in the midst of all the other delusions.”

Why the Ending is Effective

The ending reveals the ultimate plot twist. With haunting cinematography and performances to match, the final scenes in the noir-inspired film tie up all loose ends. Every red herring in the film is explained, from Teddy’s liberation of the concentration camps during WW2 to the imagined character of Rachel Solando. During the movie’s final act, every character takes off their mask and reveals the entire charade to Andrew, reinforcing themes of identity fractured by trauma, the guilt associated with memory, and the dangers of escapism.^{[12]

- Another major current throughout the film is the human mind’s susceptibility to darkness and violence, and how it can sometimes take over in the wake of tragedy.

Shutter Island Film Ending vs Book Ending

Download Article

In the book, Andrew unquestionably slips back into his Teddy delusion. The film is based on the novel, Shutter Island, by Dennis Lehane. Although the screenplay closely echoes the book, one major departure is the story’s ending. In the book, Andrew has very clearly regressed into the Teddy persona, leaving no doubt in the reader’s mind that the treatment failed. However, the movie took creative license when it came to Andrew’s true mindset in the final scene.^{[14]
X
Research source}
- The final piece of dialogue, in which Andrew asks whether it’s worse to live as a monster or to die as a good man, was added to the film to stir up doubt in viewers’ minds.
- In the book, however, Andrew refers to Sheehan as Chuck, tells him they need to figure out a way to “get off [that] rock” and implies in no way that he remembers the events of the past few days, his true identity, or his traumatic past.
- Other differences between the novel and film include the size of the island, as it is portrayed as being much smaller in the book, and the pacing, with Lehane’s narrative described more as a slow-burning mystery, gradually offering small clues that culminate in a big, explosive reveal at the end.

Is Shutter Island based on a true story?

No, but the setting was inspired by a real place. Lehane shared that the island setting for the fictional Ashecliffe Hospital was inspired by Long Island in Boston Harbor. Lehane recalls visiting there when he was young during the blizzard of 1978, which likely became the “hurricane” that “traps” Teddy and Chuck on Shutter Island. Long Island had been home to several welfare institutions, shelters, and hospitals, and although there is no proof lobotomies took place there, there is evidence of similarly unethical treatments.^{[15]

- Scorsese said he was inspired by classic film noirs like Laura (1944), Out of the Past (1947), and Crossfire (1947).^{[16]

Final Takeaways

Shutter Island concludes on an open-ended note, allowing the viewer to decide. There are two main camps when it comes to interpreting the ending of this modern noir classic. Whether you believe that Andrew genuinely slipped back into his Teddy delusion or you have a gut feeling that Andrew was pretending to be Teddy because he preferred a lobotomy over facing his truth, the final scene throws in a smaller twist-within-a-twist. In the end, it’s totally up to the viewer.
- Does Andrew’s final hypothetical question to Sheehan simply reveal a moment of clarity in the otherwise murky waters of a madman’s mind?
  - Or does it suggest a secret awareness and a coherent choice to end the suffering of remembering once and for all?
