After Hrithik Roshan and Shah Rukh Khan, it is Kunal Kapoor's turn to play a superhero in Anurag Kashyap's "Doga" -- and he says the film is an ambitious project.

"'Doga' is a really ambitious project and the script is being worked on... It will take a while before it finally takes off. When I was offered the role, I thought I might not be the right choice for it, but then I accepted it because it was very interesting," Kunal told.

"Doga" is a comic book character. The story is about Suraj, an orphan brought up by Daku Halkan Singh who treats him like a dog. To seek revenge, Suraj becomes Doga and hides his identity behind a dog mask. He's a one-man army against organised crime.

The 34-year-old, who is gymming religiously to sport a bulkier look for the role, doesn't believe in crash diets to attain a particular body type.

"Well, honestly I don't believe in crash diets or other fads... I think if you are working towards a body type, you need to give yourself enough time and set realistic goals, so that you don't have to do anything that will harm your body," he added.

The 34-year-old, who got recognition after his acclaimed performance in the hit film "Rang De Basanti", went on to do films like "Laaga Chunari Mein Daag", "Aaja Nachle", "Bachna Ae Haseeno" and "Lamha", among others.

Meanwhile, the actor, last seen in Shah Rukh Khan-starrer "Don 2: The King Is Back", is currently shooting for the movie "Luv Shuv Tey Chicken Khurana".

"We live in a country obsessed with food, yet ironically, we have never made a film about food. This is a film about a large Punjabi joint family, and a magical recipe that goes missing. It's a family entertainer, but it has enough twists and turns and pushes the boundaries enough, for even someone like Anurag Kashyap to be interested. It's our spin on the family entertainer," he said.
