"According to me, I have been working for 16 to 17 years but this is one movie that will remain very close to my heart. At that time I was not a producer. But there is one wish that will remain unfulfilled that I wish I had made this movie," Shah Rukh told STAR Gold.
In the 1993 film directed by Kundan Shah, Shah Rukh played an aspiring musician with a never-say-die attitude.
When asked if there is any similarity between him and his character in KHKN, he said: "I would like to be like Sunil but I don't think I have the innocence and purity of Sunil. But Kundan has that quality of innocence and sweetness like 'Wagle Ki Duniya'.
The never-say-die attitude that Kundan's character have is very enduring. He can bang his head on a wall and still say that I am going to win."
Shah Rukh, who turned producer with "Phir Bhi Dil Hai Hindustani" which was on the commercialisation of news, said the movie was a culmination of his friendship with Juhi Chawla and Aziz Mirza - partners in his production company Dreamz Unlimited.
"Raj Kapoor had once told me that a disabled child is closer and more special to the parents. I did not understand it then but after making this movie, Aziz, Juhi and me realised this. This movie was a culmination of our love and friendship.
"We wanted to make a movie and become producers. There was a man who was sitting with us, not from the industry, and said: 'I will make a movie if the three of you are associated with it.' We were very ashamed that if he can have so much faith why should we not have it in ourselves.
"And then we decided to make 'Phir Bhi Dil Hai Hindustani'. The idea was about commercialisation of news. At that point India did not have so much TV and I won't say that we could foresee the future but if we see it today, TV news is nothing."
Shah Rukh is very popular among his female co-stars but for him Juhi is the most special co-star.
"She is a friend, someone in the film industry who I owe a lot to and will always remain that way. Juhi is very special to me. One of the greatest experiences that I have with Juhi and Aziz is that we shared our ups and downs, our success and failure. We have laughed a lot together and cried as well.
"I remember the first report of 'Darr' was not very good and the movie was very important for me and Juhi. We were worried. We were almost crying. Usually, there are mixed reactions on the first day.
"'Phir Bhi Dil Hai Hindustani' was a step forward from our friendship. After that we made many more movies like 'Chalte Chalte', 'Ashoka'."
Shah Rukh gives credit to his fans for his success.
"I'm the luckiest man in the world and I don't want to hide from it. I cannot repay my fans for what they have done for me, they have given me so much love and that love has taken me to where I am today. The only thing I can do for my fans is to never stop working, and to do films till the very end, it is the only way I can express my love for them."
