"To be fair to my other directors, I brought a certain amount of experience in this movie but this is a side that people have not seen before. There is a change in my attitude towards work. It's like I have tasted blood," he told PTI.
Sidharth credits director Shakun Batra for bringing the best out of him in the ensemble family drama, also starring Fawad Khan, Alia Bhatt, Ratna Pathak Shah, Rishi Kapoor and Rajat Kapoor. "In the first few films, everything was very new and there was a lot more questioning in my performances. But this role was closest to what I am in real life. Shakun did not want me to portray something, he said I want you to draw from you for this part. This is by far the maximum fun I had on a film set."
It is an interesting journey for Sidharth, who stumbled into the film industry after dabbling with modelling and assistance direction. "I became an actor due to various accidents. I am happy that they happened because I was very lost as a child and did not know what I was good at. I used to feel that I will not be able to do anything in life. But now I feel I am in the correct profession where I need to know a little bit of everything."
Sidharth, 31, says while they were making "Kapoor & Sons", they had no idea that it will find such acceptance. "We thought the film will have a narrow audience. We knew that it was a good film but the universal appeal that it has got is overwhelming and unexpected. I have never got such response for any of my films so I am holding onto this feeling and hope I get more chances to feel like this," says Sidharth.
The actor does not have much time to relish the success of his latest movie as he is back in action with two back-to-back movies -- an untitled action drama and "Baar Baar Dekho" with Katrina Kaif. He, however, denies that the action film is a sequel to "Bang Bang!".
"I am doing an action film, which is untitled. It is not 'Bang Bang 2' or related to that story. I have grown up on action movies and as an actor I like to beat up bad guys on the screen. The boy in me gets very excited."
The actor says 'Baar Baar Dekho' is 70 per cent complete and will hit the theatres in September this year. "It is a concept love story where there is some fiction in your life. It is about a man who gets a chance to see his life ahead and then what he does with it. We are mixing fiction and fact in a story. It is not time travel but this man gets a chance to see the future."
