Emraan Hashmi, who will be seen as a porn filmmaker in Dibakar Banerjee's upcoming political thriller "Shanghai", Sunday said he had gained nine to 10 kg for the role.

This film is all set to release June 8.

Hashmi said he plays the role of a porn filmmaker called Joginder Parmar.

"I play the role of Joginder Parmar. He is a very rooted and real character. He is extremely interesting and you would all love him. It is very different from what I played in 'Kalyug'," he said at the music launch here.

Hashmi's look is very different in the movie.

"There were a lot of look tests after the character sketch was given. Eventually this one emerged. I had to put on weight for this character. I had to go two shades darker. In the morning, we used to prepare for this, before the shoot."

"I had to even work on my teeth and put things on it to get the look. I dont know how many actors would want to look grotesque on screen. When Dibankar told me, he thought I would say no, but I didn't. I think its a great opportunity," he added.

"I gained nine-10 kilos. I had to start changing my diet and eat only fast food and pasta on the set."

The cast includes Abhay Deol, Kalki Koechlin and Bengali actor Prosenjit Chatterjee.

Talking about the film, Hashmi said: "Its a very normal film. Its relevant and the story is very interesting. I am sure this film will be a landmark film for us. Its an interesting film. We have maintained a commercial outlook with the music of this film."

After back to back hits like "Jannat 2" and "Murder 2", Hashmi seems to be one of the biggest stars of Bollywood today.

Asked whom he wants to dedicate this success to, he said: "I have always said that when a film does well, its because of the team. The entire team contributes to it. It is a synergy of talent. Even if 'Shanghai' works, its a team effort. A lot of work goes into a film and its a lot of departments who work together."
