In his eight year long career Neil Nitin Mukesh may have played various negative characters, but the actor says the role he has in upcoming film 'Wazir' is his darkest portrayal yet.

Neil, who made his debut with 'Johnny Gaddar', stars in the titular role as an antagonist in the drama-thriller directed by Bejoy Nambiar.

"'Wazir' is nothing but dark, he mocks and enjoys somebody else's pain. This is my darkest portrayal yet. I myself was quite shocked that I played this character. He is very unpredictable... Whether it's his face, voice or look, I had to work extremely hard for this," Neil told PTI.

The 33-year-old actor said filmmaker Vidhu Vinod Chopra, who is producing 'Wazir', was so impressed with his performance that he changed the name of the film.

"When the film was offered to me, at that time it was titled 'Ek aur Ek Do'... After I finished shooting, I got a call from Vidhu sir and he said 'What have you done?' I asked him if he was not happy with my performance. He said, 'Happy?

I am changing the name of my film to Wazir now.'" The film tells the story of two unusual friends -- a paralysed chess grandmaster, played by megastar Amitabh Bachchan and a grief stricken ATS officer, played by Farhan Akhtar, brought together by a twist of fate.

Neil said it was extremely tough to intimidate Bachchan, even though he was playing a character.


"When I got to know that my character would be intimidating Bachchan sir's character, that was scary. His name is itself intimidating so getting on screen trying to intimidate him was not an easy task.

"But, that's where the acting kicks in. I did not want my nervousness to affect his performance so I made sure all the butterflies which were fluttering in the stomach, remained there and never came out on face," he said.

'Wazir' marks Neil's second outing with Nambiar, as the duo previously worked in "David". Neil says he shares a great director-actor tuning with the "Shaitan" helmer.

"In the next two-three years, Bejoy is going to be numero-uno. Luckily for me, our tuning is extremely strong. I understand his technical aspects and I try to execute them along with the emotional bit in character. The balance between a director-actor fits perfectly."

Even though the actor has played characters with grey shades in movies like '7 Khoon Maaf', 'Players' and recently 'Prem Ratan Dhan Payo', Neil says he is open to do romantic stories as well.

"I am always attracted to do of characters which are not easy. I would love to do a nice love story. If there is a story that attracts me I would love to do it, like 'New York' which I consider a love story.

"It is not like I don't want to or can't play characters which are clean. But grey sides give you a lot of scope to show your potential as an actor."

'Wazir' is scheduled to release on January 8.
