A few more observations to add to my previous post:
The author of the book on which the movie was based has been credited in the titles right at the start in a big font.
Once the movie ended, people rose to move out of the theatre but did not really walk out. Everyone waited to watch all the 'rolling titles' till the very end. Was it a fall out of the present controversy related to Chetan Bhagat's book and the movie 3 Idiots? Cant say.
