‘Oh Butterfly’ movie review: An intriguing and affecting rumination on guilt

Does everything happen by design or destiny? Do all actions have a cause and an effect? If something as negligible as a butterfly flapping its wings can, in theory, cause a tornado, do all things have a similar, seemingly unrelated, minuscule cause? And if so, can you somehow be the cause of something so big? If so, can anything and everything you do result in something catastrophic? An inquiry into the Butterfly Effect seems like an intriguing exercise, though the tone can turn drastically if the tornado caused by the butterfly upends your life, or rather, if you were the butterfly that caused a tornado. A hapless victim of fate gets imprisoned in this line of thought in Oh Butterfly, a two-hour rumination on guilt directed by debutant Vijay Ranganathan.

In the long, sleepless eyes of Gowri (played with excellent control by Nivedhithaa Sathish), we see a woman lost to the storms of life. She tells her newly-employed maid about how she suffers from a condition that prevents her from being in the same room as her, and we are soon shown what precisely happens to Gowri should she attempt to break this self-imposed constraint. Suffering from extreme Harm OCD as a result of the death of her husband, Gowri’s mind restlessly conjures scenarios of how her mundane actions could hurt others. For instance, the thought of helping the maid in the kitchen brings up scenarios through which she inadvertently plunges a kitchen knife into her throat. What caused this extreme paranoia in Gowri is what we interrogate as her spiritualist sister, Ranjani (Lakshmi Priya Chandramouli), helps her open up.

Right off the bat, the introduction to this world sets up the tone and temperature that director Vijay impressively maintains throughout the film. The main narrative of the film begins some 40-odd hours before the death of Arjun (Attul), Gowri’s husband, as they enter their Kurinji summer home in Kodaikanal — placards of the hours before the inevitable death act as the ticking time bomb that helps us track the time and thereby the urgency of the proceedings.

Gowri, we realise, has brought Arjun on vacation to confess something she had been hoping to ever since their wedding four months ago. Just as she is about to broach the topic, Gowri gets the shock of her life when Suriya (Ciby) — Arjun’s college friend, who, unbeknownst to the former, is also Gowri’s ex-lover who once betrayed her — makes a surprise appearance. A lean and effective thriller that compels your attention follows.

Character-writing is the biggest strength of Oh Butterfly as Gowri, Arjun and Suriya all immediately strike a chord as people we might have come across at some point in our lives. The writing of Arjun, especially, is a tight-rope walk since this is an ever-anxious, hair-trigger-tempered, miserable man who is meant to both evoke pity and get under your skin. Unfairly fired from his job, Arjun is desperately looking for funding for a new start-up that is ready to take him in. The moment Suriya enters, Arjun believes that they were destined to meet and suspends everything at a moment’s notice, assuming Suriya would serve his cause. At the same time, the lack of chemistry in his marriage is becoming a cause of stress. He shuttles between extreme emotional poles so quickly, and writer-director Vijay finds in Arjun a nervous child who goes to any lengths to feel a win.

Meanwhile, Ciby manages to come across as a man you are always wary of for some unexplained reason. Suriya appears harmless and even carries a free-spirited hippie energy, and yet everything he says feels quietly caustic. And stuck between these two cut-outs of fractured masculinity is Gowri, who spirals in guilt as a helpless spectator.

However, the characters who would truly leave a mark and elevate Oh Butterfly to a deeply philosophical space are those of Sagayam (the ever-impressive Nasser) — the home’s caretaker and an oddball butterfly-breeder who somehow can smell death when it is right around the corner — and his newborn butterfly Jebamani. Much of what Sagayam utters (though sometimes seeming like expository philosophising) stays with you, like a dialogue about what matters in a lifetime that spans only 15 days. The butterfly, on the other hand, becomes an allegory to Gowri herself, and what many of us like Gowri fail to see about our short lives.

Writer-director Vijay shows a great knack for writing metaphors and motifs. A golf ball for instance, becomes both a liberator and a destructor. Similarly, the use of composer Vaisakh Somanath’s superb compositions adds to the very specific atmosphere the director has opted for. Also deserving of credit are the performers; given that much of the film revolves around three or four characters, a lot rests on the shoulders of the leads, and they ace it with ease. How great it is to see veteran actor Nasser in roles like these; even with his relatively short screentime, he makes his presence felt effortlessly.

Sure, there are contrivances, like a moment towards the end that is about Suriya, or how the arc about Soda Buddi Kezhavi, an astrologer played by Geetha Kailasam, ends. But Oh Butterfly isn’t desperate to impress. As the well-cut trailer revealed, it is a film aware of its scale and ambition. And at a time when Tamil films seem too eager to achieve greater heights, this is a film that manages to stir something strong in you by merely flapping its wings and seems all the more content with the heights it soars.
