David Fincher’s “The Killer” is a cold, riveting, and dark tale depicting an assassin’s calculated hunt for vengeance. Fincher, screenwriter Andrew Kevin Walker, and the rest of the cast and crew know precisely how to immerse the viewer in a world of darkness, where murder seems natural, inconsequential, and even necessary. While Fincher has explored the male loner’s attraction to violence in films like “Fight Club,” “Se7en,” and “Zodiac,” he continues to take a deadpan, procedural approach to the goriest of crimes in “The Killer.”

The Killer (Michael Fassbender) is only known by that name. We’re introduced to him as he plots his next hit. He narrates his story by detailing the monotonous repetition of his job. He rationalizes his murders as nothing more than a blip for the population. He does yoga; he listens to The Smiths; he eats McDonald’s; oh, and he kills people for a living. “The Killer” isn’t concerned with telling us how he got here, his name, or any details about his employment or his hit. “The Killer” provides so little background, but we are constantly learning and engaged by how the story is being told. 

In a fraction of a second, The Killer’s mission goes wrong when he accidentally misses his target. It’s rare. Worst-case scenario. After telling his employer, The Killer understands his life and his family are now in danger. Those are the rules. If you miss your target, you now have a target on you. The Killer rushes to his home and finds out his girlfriend has been brutally attacked by two assailants: one man and one woman. The Killer makes his new mission a crime of passion: to find and kill whoever planned and attacked his family.

From its plot description to its title, “The Killer” is straightforward, nondescript pulp fiction. The plot and title blend in with countless other action and crime movies, but Fincher once again develops an engrossing, murky atmosphere that feeds the viewer’s most twisted thoughts. “The Killer” makes the trashiest grindhouse movies feel like art. Never before has a Hawaiian shirt and fedora felt so sinister.

“The Killer” Review

Our Rating: Positive (Worth Seeing)


Methodic in Exposition and Intoxicating in Details

“The Killer” casts its own spell on the audience by being methodical and deliberate in what the story reveals. The film rarely repeats key details and keeps The Killer’s next move a secret; the movie trusts the viewer to make connections (like tracking down a cab driver) and remember details (like an assailant having a hurt leg), and seeing how The Killer slowly discovers who’s trying to kill him makes for an absorbing watch. 

“The Killer” Sinks You Directly Into The Killer’s Mind

the killer 3

The first 20 minutes of “The Killer” show what the daily job looks like, with Fassbender narrating his existential musings and necessary indifference to his actions. We await violence and anticipate it to happen. But when the assassin’s mission goes wrong, we’re thrown into panic, just like The Killer. If the viewer supports or condemns The Killer’s actions, it becomes irrelevant when we’re already in his shoes, swallowed by his mind, and know exactly what he has to do. The narrative repetition of key phrases, close-ups of Fassbender’s cold stare, and a world where deals can be hidden in shadows but murder can happen in harsh light make the audience complicit in crime too. 

On The Fence

“The Killer” Can be Misconstrued as Another Violent Loner’s Manifesto

“The Killer” may be violent and disturbing; the movie is also filled with Fincher’s trademark dark humor, witty retorts, sickly yellow lighting, and philosophical musings about people and society. Some may see “The Killer” as another entry into what Fincher does best, like in “Fight Club,” where he immerses you in the mind of a lonely male psychopath. But just like how “Fight Club” or “American Psycho” can be argued to condemn or mock that mindset, some may be inspired to see “The Killer” as a badass hero. This isn’t a criticism of Fincher or how others interpret his movies, but sometimes it feels that he’s simply made this movie before.
