Engineer Hayasaki (Koji Yakusho) is working on a robotic chair that allows paralysed people to operate artificial limbs through a connection with the brain. One day he comes home to find a doppelganger who attempts to help him push the project on, while also causing havoc through his aggressive behaviour. Meanwhile, a young woman Yuka (Hiromi Nagasaku) is disturbed to hear of her brother’s suicide, while his doppelganger sits at home working on a novel. Hayasaki’s double hires an assistant called Kimishima (Yusuke Santamaria) to help with the chair; continuing their work in an abandoned warehouse even after Hayasaki is fired from the medical company that had funded his research.
“Doppelganger” is a mix of horror, classic science-fiction, and mystery, with a tone that shifts from dark to humorous. The uncomfortable atmosphere is compounded by a plot that becomes increasingly wild as it reaches a dramatic climax, even abandoning the doppelgangers towards the end. Writer-director Kiyoshi Kurosawa expects the audience to engage with the film, rarely explaining things, or even explicitly revealing what is happening. Instead we experience Hayasaki’s bizarre situation first hand and are asked to make our own minds up about what is real or unreal, and the significance of the doppelgangers. This is even more keenly felt in the story of Yuka’s brother, Takeshi, a disturbing situation that appears and is resolved without any apparent connection to Hayasaki’s own problem. Kiyoshi excels at creating uncomfortable moments, using space and framing that suggests unseen or unknown horrors. Even the smallest moments take on a sinister aspect and we are left anxiously awaiting some new terrible revelation. However, the film also balances this darkness with a blackly comic tone, with Hayasaki’s unhinged behaviour not quite tipping over into something more pitiful. Koji Yakusho does a fantastic job with the two Hayasakis, who have distinct personalities and approaches to work and life. The film utilises simple yet effective techniques to show the two of them together and we can feel that they are two different people who happen to look identical. The use of split screen is also a great addition, adding to the uncertainty about whether this is Hayasaki’s delusion or a manifestation of Hayasaki’s darker nature. The score by Yusuke Hayashi captures this strange blend of horror, comedy and science-fiction, with ominous chords and jaunty melodies.
Kiyoshi Kurosawa’s “Doppelganger” explores the duality of its protagonist Hayasaki and that of humanity in general. Hayasaki is a man who has devoted his life to his work, neglecting any kind of social or romantic pursuits. His doppelganger, more assertive, aggressive, and decisive, represents those elements of himself he has kept hidden, agressively pursuing Yuka. Hayasaki’s dislike of his double shows how much he wants to distance himself from these elements of his own psyche. Takeshi’s case is more tragic, suggesting the choice that lies before many people, with his ‘real’ self committing sucide while his doppelganger pursues his creative tendencies.It is the Id-like doppelgangers that seem to know what is truly important to the individuals, while the true self of the Ego is forced into a life controlled by others. The film’s upbeat ending sees things resolved in a positive if unconventional way, but one that chimes with the underlying message of self-awareness and self-discovery.
