Mumbai, Nov 30 (PTI) Actress Vidya Balan, who is essaying a sultry siren in soon-to-be-released 'The Dirty Picture' against actor Naseeruddin Shah, says age difference between the duo did not matter for her while shooting intimate scenes even as she asserted that the movie is not porn.

From being a demure dame in 'Parineeta' to a sly temptress in 'Ishqiya' and now a southern siren in 'The Dirty Picture', actress Vidya Balan has come a long way. Milan Luthria's 'The Dirty Picture' chronicles life of the controversial southern actress Vijayalaxmi, popularly known as Silk Smitha who was known for her daring and bold erotica on screen.

The promos of the flick have already become the talk of town. However, the actress is all praise for the veteran actor. "The age difference did not matter much with him (Naseeruddin Shah). When you face an actor like Naseeruddin, he can make you believe in anything. He is a brilliant actor. And I have worked with Naseer saheb earlier.

 He is one of the living legends. You feel absolutely comfortable, I was not at all uncomfortable," Vidya told PTI in an interview. "In such scenes, we made sure few people are there on sets. I knew it was required for the story to go ahead...it was part of the script," she said.

Earlier, Vidya shared screen with Naseeruddin in Vishal Bharadwaj's 'Ishqiya'. About her experience of working with Naseeruddin, Vidya said, "it was heart warming, especially while shooting 'Ooh La La' song. When we were dancing in the midst of oranges it was hilarious. We were laughing like mad, dancing between pots, posing like old sculptures. We had to roll down a slope. It is not easy, more than (getting) hurt, I couldn't control my laughter."
