Above said, in the end, this movie turned out to be more of a tribute to his father Sunil Dutt who despite against all odds of life, stayed firm in his character. Fighting life with son turned into a drug addict, wife dying of cancer, taking flakes for supporting and protecting minoriy as a city leader after Mumbai blasts, getting called a hidden Muslim as he was born in Pakistan, before partition. {This was actually a payback as Dutt's family was saved by a Muslim friend during 1947 migration}.
Though it was not mentioned in the movie Nargis fall in love with him and remained his true love till the end as he saved her from a raging fire broke out during the making of the film 'Mother India', another aspect of his brave character.
I had a discussion about his strong character with one of my friends. Sunil Dutt was born and raised as a farmer near Jhelum, Pakistan. Is this true that people who are more near to soil have more strength to their character in contrast to urbanites/city dwellers?
