Bollywood's 'serial kisser' Emraan Hashmi feels that veteran actor and co-star Naseeruddin Shah has got bolder and dirtier in their upcoming film 'The Dirty Picture', inspired by late Southern sex siren Silk Smitha's life.

"As far as the bold quotient goes...I am doing my own bold stuff but Naseer is the boldest in the film. I think he has taken all my mantle in the film and he is doing what I use to normally do in films," Emraan, who earned the 'serial kisser' tag after Anurag Basu's 'Murder', told.

On scenes with the senior actor, Hashmi said, "We had two-three short scenes..there is a premiere and party shots but not many. They cross paths as they are in the same industry. Naseer is an actor, Tusshar is a struggling writer, Vidya is an actress. As you are being part of same industry so you end up meeting people."

The Milan Luthria-directed movie sees Emraan essaying the role of a director. The actor claims that the film would have been incomplete without casting him.

"Everyone...everything is dirty in this film. It is the dirtiest film I have done. You cannot make a dirty picture without Emraan Hashmi," he said.

'The Dirty Picture' is inspired by sex icon Vijaylakshmi better known as Silk Smitha. The film shows the highs and lows of an actress-dancing star.

"The tone of the film is bold and provocative. But it does not cross the line into vulgarity.. Vulgarity is always subjective. The film is bold in terms of language also and few people might feel it as dirty and take it as an offence. The concept is bold but at the same time entertaining," Emraan said.

Due for release on December 2, the film stars Naseeruddin Tusshar Kapoor and Vidya Balan.
