Who said anime can’t pull crowds in Indian theatres? Doraemon: Castle of the Undersea Devil is quietly writing history. After a steady second week, the film has crossed Rs 23 crore gross in India and become the franchise’s biggest Indian grosser ever.

Week 2 Report: A Fair Hold

The anime earned Rs 9.50 crore in its second week, a 35% drop from week one. That is a healthy hold for a film this far into its run. The second Thursday added an estimated Rs 50 lakh. Trade estimates suggest a final lifetime of about Rs 27 to 30 crore gross.

The previous best for any Doraemon film in India was around Rs 5 crore. If the projection holds, this one will finish with roughly six times that figure. Not bad for a franchise many treated as just kids’ entertainment.

What Is the Film About?

Nobita and his friends set off on an undersea camping trip using Doraemon’s futuristic gadgets. Their adventure leads to the hidden Mu Federation, where they learn that Poseidon, the rogue AI of the ancient Atlantis civilization, has activated a weapon that could destroy Earth. Teaming up with Mu’s El, the gang ventures into the Bermuda Triangle to stop it. It is part adventure, part sci-fi thriller, and fully heartfelt, as only Doraemon can deliver.

Why Is It Working?

A few things seem to be helping:

  • Nostalgia: millennials who grew up with Nobita are now bringing their own kids.
  • Family-friendly appeal: an easy pick for weekends and holidays.
  • Weekend spikes: Rs 2.50 crore and Rs 2.75 crore on the second Saturday and Sunday show strong word of mouth.
