Actor Ronit Roy says his role in '2 States' is more of a guest appearance and that his character will have shades of grey.
Being directed by Abhishek Verman, it is being co-produced by Karan Johar's Dharma Productions and Sajid Nadiadwala's Nadiadwala Grandson Entertainment.
This will be Ronit's second film with Karan Johar after 'Student Of The Year'.
"I am doing '2 States'. I got a call from the production house for the role, but I told them I don't want to do it. Then I got a call from Karan, he said, 'Why are you not doing this film?' I couldn't say no. Karan said trust me, so I went ahead and did the film," said Ronit.
The film starring Alia Bhatt and Arjun Kapoor is a big screen adaptation of Chetan Bhagat's bestseller '2 States: The Story of My Marriage'.
" '2 States' is an intense story and it's a sort of negative role. I am playing Arjun's father's role. It's like a guest appearance and the character speaks a lot in it," he added.
In the film, a Punjabi boy falls in love with a Tamil girl, which leads to a regional and cultural clash.
The ace actor, who is ruling the small screen, wants to do films with knowledgeable people.
"I don't feel I have so much of knowledge that I can carry a film on my shoulders," said Ronit, who had impressed with his performance as a strict father in Vikramaditya Motwane's 'Udaan'.
The actor, who started his career with movies like 'Jaan Tere Naam', is happy with his work on the small screen.
"I am happy in my small world. I just see who is making the film and the person who is making the film should be knowledgeable," said Ronit, who is seen as a a lawyer in the popular TV show 'Adaalat'.
