Shruti Kalra can never watch a film at the cinema without having to nudge the person next to her. “Every time there’s a silent scene, I need to ask them what’s going on,” says Kalra, a Delhi-based professor, who is blind. She only dares going to see a film with someone she knows won’t mind the disturbances.

But when she watched the wildly popular Bollywood biopic Sanju things were different. As the film began, she opened an app on her smartphone and plugged in her earphones. A few taps later she was listening to an audio description of the movie, for the first time in her life. “I felt so independent just to be able to follow and understand the entire film on my own,” she remembers.
