Doraemon: Castle of the Undersea Devil is on track to become the second-highest-grossing anime film in India, with a net collection of ₹8.35 crore after four days. The film, a remake of the 1983 classic, has defied expectations by pulling in ₹1.95 crore on opening day and holding strong with ₹1.25 crore on Monday — only a 35.9% drop despite limited theatrical runs. That’s not just a bounce. It’s a full-on nostalgia surge. And it’s not just kids. The audience mix? A wave of millennials riding the memory train, drawn by the cartoon that once ruled schoolyard afternoons. The film’s momentum is clear: it’s already the fourth highest-grossing anime title in India, and trade sources suggest it could overtake both Shinchan: Our Dinosaur Diary and Suzume by week’s end. On BookMyShow, it’s sitting at a near-perfect 9.2/10 from over 5,500 votes, proof the love isn’t just emotional, it’s loud. But here’s the twist: it opened against Drishyam – The Conclusion, a major thriller with star power and built-in buzz. Still, Doraemon held its ground. Not because it was louder, but because it was more familiar. So what happens next? The film’s fate now hinges on weekend turnout. If the momentum carries through Friday and Saturday, it won’t just break records. It’ll rewrite them. For now, the box office says: this isn’t just a revival. It’s a comeback.
