The national anthem was played and everybody in the hall stood up. This was before the film had begun. However, during the national anthem played in between Dangal when the girl won a wrestling gold, nobody stood up. Nobody even so much cared for patriotism or nation or treason. A few were sipping their cokes, and others their coffee, while munching on their popcorn, and their sandwiches, or biting into their momos, or chewing noisily on their nachos. There were hushed whispers as to how the climax of the film came about. Still nobody stood up during the national anthem.
I thought the national anthem had to be respected irrespective of whether it is played before the screening of the film, after, during and whenever it is heard/played.
