Kunal Deshmukh - If I have to make Devdas, how would I do that? Would I give him a glass of 'sharbat' in hands? Also, in certain scenarios, you have to depict evil with certain traits. This only helps in building a story graph with ultimately good winning over evil.
Chunkey Pandey - There would soon be a time when a character would have to go off-focus from camera, director would have to 'somehow' convince the audience that the character is drunk and the character returns and acts in front of camera like he/she is in a drunken stage. Voila, mission accomplished!
Sanjay Khanduri - I agree that drinking should not be glamorized, but then it should not be banned either. If a character has to be shown to be carrying certain evil traits, should we replace drinking by cocaine?
