Is this still the case? It's been probably over 10 years since I saw a movie in an Indian theater, so my memory is hazy.
Recent films that I can remember: John Wick 4, Top Gun: Maverick, NOPE.
All of them had the forced break.
It was a cultural adjustment for me with American theaters and no intermissions, even for the very long films. Funnily enough, since I went to a couple of Broadway shows before the movie theater, I was primed to expect an intermission in the movie theater as well, at least for some movies. What I do note is that the audience is consequently more prone to walk out to restrooms and concession stands at any time during the movie, which can be annoying.
