10 Thriller Films Where the Main Character Is Actually the Culprit, The Ending Will Shock Your Reasoning

Kapanlagi.com - The world of thriller cinematography has created many masterpiece works that not only evoke the emotions of the audience but also present plot twists that truly change the perspective on stories enjoyed for hours. The thriller genre, with its elements of surprise and revelation that make the main character the mastermind of the crime, is one of the most effective formulas in modern filmmaking, as it can make the audience feel deceived yet still amazed by the narrative cleverness presented by filmmakers. Films like this not only entertain but also provide a deep and memorable viewing experience, where every detail of the story feels important and should not be missed.

The uniqueness of thriller films with the protagonist as the perpetrator lies in their ability to build audience trust in the protagonist character, only to then shatter all those assumptions with a dramatic and meaningful reveal. This storytelling strategy requires extraordinary skills from screenwriters and directors, as they must balance providing enough clues for observant viewers while still maintaining mystery until the right moment. The experience of watching such films often makes the audience want to rewind the film to catch all the details missed at the beginning, creating an incredible long-term value in the world of film entertainment.

1. Memento (2000)

Memento (2000) (imdb.com)

The film Memento by Christopher Nolan is one of the most innovative works in the history of thriller cinema, using a reverse narrative structure to tell the story of a man suffering from anterograde amnesia, unable to form new long-term memories after a traumatic accident. Leonard Shelby, the main character played by Guy Pearce, has a medical condition that makes him forget every ten minutes, forcing him to rely on written notes, Polaroid photos, and tattoos etched all over his body to track clues about his wife's killer. Throughout his journey of revenge, the audience is led to believe that Leonard is a fearful victim, a desperate man seeking justice for his murdered wife.

However, as the film progresses with its backward structure, it is slowly revealed that Leonard is actually the killer who keeps repeating the same murder over and over due to his condition that makes him forget, and he has created a complex manipulation system to keep himself on a false path of revenge.

The most shocking twist is when it is discovered that his wife was actually not murdered; rather, he himself killed her because he could not bear to see her suffering from diabetes, and then created a false narrative about a mysterious killer to give meaning to his life. Leonard, consciously or unconsciously, has become a serial killer targeting those who are told they are "his wife's killer," while he is actually the mastermind behind all the tragedies that occur in his life.

2. Oldboy (2003)

Oldboy, a brilliant work by director Park Chan-wook, follows the story of Oh Dae-su, an ordinary man who is suddenly kidnapped and imprisoned in a small room for a full 15 years without knowing the reason or purpose of his abduction. For years in isolation, Dae-su only has a television as a means of entertainment and food that is placed through a hole in the door, creating frustration and resentment that accumulates in his soul as he endlessly speculates about the identity of his kidnapper. When he is finally released without explanation, Dae-su eagerly embarks on a quest to find the person responsible for his years of disappearance, showcasing a brutal and physically violent act of revenge.

His journey of vengeance leads him to a wealthy man named Oh Woo-jin, who turns out to have a complex past relationship with Dae-su from years prior. In a devastating twist, it is revealed that Dae-su himself is responsible for Woo-jin's sorrow due to his reckless actions in the past, when he said something fatal that led to the death of someone very dear to Woo-jin. Woo-jin is essentially the life sentence for Dae-su's actions, and the 15-year kidnapping is the most cruel and patient form of revenge ever planned, making Dae-su not only a victim but also the main cause of his own tragedy, which then results in a never-ending cycle of violence.

3. Black Swan (2010)

Black Swan (2010) (imdb.com)

Black Swan, a masterpiece by Darren Aronofsky, tells the story of Nina Sayers, a highly dedicated ballet dancer competing for the lead role in a major production of "Swan Lake" that will showcase both sides of the swan character, the soft white one and the dark, passionate black swan. Nina initially appears as a pure and dedicated artist, a woman living in a strict environment with a mother who was also a former ballet dancer, pouring all her energy into achieving perfection in her art and balancing her difficult emotional state. However, as Nina prepares for the performance that will change her career and life, the line between reality and fantasy begins to dangerously blur in her increasingly unstable mind.

When a new dancer named Lily appears and seems to threaten Nina's position, Nina's obsession with perfection in dance and her fear of being replaced create a deteriorating psychological condition that ultimately leads to extreme hallucinations. Throughout the film, viewers alternately find themselves unsure whether what they are seeing is real or just a projection of Nina's fractured psyche, creating a haunting uncertainty. The final twist reveals that Nina has experienced a severe psychological breakdown and has committed brutal acts of violence, including killing or seriously injuring Lily, while her mental state continues to fracture and she can no longer distinguish between her gentle self (white swan) and her dark side (black swan) that has taken full control of her actions.

4. Usual Suspects (1995)

Usual Suspects (1995) (imdb.com)

The Usual Suspects is a masterpiece by Bryan Singer that tells the story of five ordinary criminals who are caught in an incident involving a murder at the docks, where they are then interrogated by the police trying to understand who is really behind the large-scale crime operation that harms many parties. The five suspects then recount a legendary figure named Keyser Söze, a genius criminal who is described like an urban legend about a figure who is nearly impossible to catch, possessing extraordinary skills in planning and executing crimes without ever leaving clear evidence. The audience, along with the investigators, believes in the narrative constructed by the four criminals, creating an imagination of who Söze really is and how he operates.

A twist that truly changes the game occurs at the end of the film when it is revealed that Verbal Kint, the weakest and seemingly harmless character among the five suspects, is actually Keyser Söze himself who has planned the entire operation with remarkable precision and has manipulated all parties including the police investigators. Verbal Kint has built a false narrative about Söze through the story he presented to the investigators, using fear and legendary reputation as psychological weapons to create distrust and fear among his opponents. As Kint is released from police custody due to being deemed innocent, he literally transforms into Söze, walking confidently towards the vehicle waiting for him, revealing that he is the mastermind behind all the crimes and manipulations that have taken place throughout the film.

During the dramatic and tension-filled trial process, Martin skillfully defends Aaron by showcasing the past violence the boy has experienced and the trauma he has endured, creating an engaging narrative about a system that has failed to protect vulnerable children. However, a confusing twist that changes the audience's perception arises when it is revealed that Aaron is actually the true killer who has perfectly manipulated Martin and the justice system, using his weak and fearful persona as a perfect disguise to hide his calculated and premeditated murder.
