Kunal was last seen in the 2012 release "Luv Shuv Tey Chicken Khurana" with Huma Qureshi.
The actress was present at the trailer launch of "Kaun Kitne Paani Mein" here on Wednesday when he was asked to explain why he is doing less film and is there any plan to do more movies after "Kaun Kitne Paani Mein".
"I hope so... I was just looking back at my career and I have realised that I have done very few films and I don't think that's a good idea. I intend to to a lot more work," he said.
Kunal made his debut in 2005 with M.F. Husain-directed "Meenaxi: A Tale of Three Cities". After that he did multi-starrer films like "Rang De Basanti", "Laaga Chunari Mein Daag", "Don" and "Aaja Nachle", among others.
Explaining the reason for doing very few films in his decade-old career, he said he only does films that excite him.
"There are two ways in life... one is just do whatever comes your way and the other is just do what excites you. So far I have chosen the latter. Hopefully, there will be scripts that I enjoy so I will be able to stick to the latter, but if that is not a possibility then I think I have to take a slight step towards the other side," he added.
"Kaun Kitney Paani Mein" talks about the issue of water crisis in India and also stars Radhika Apte, Gulshan Grover and Saurabh Shukla in key roles.
The film is slated to hit the theatres later this year.
