Bollywood Megastar Amitabh Bachchan says his forthcoming film 'Nishabd' deals with the psychology of a 60-year-old man who falls in love with an 18-year-old girl.

''The film dwells with the genuine emotions of the man and the effect it has on his family when confronted with such a situation and how they deal with it. The audience understand the honest and genuine feelings of my character in the film rather than sex and sensuality,'' Bachchan said at a press conference after the music release of Ramgopal Varma's latest film which stars himself and newcomer Jiah Khan, here last night.

Nishabd releases on March two. Filmmaker Vishal Bharadwaj has composed the music of the film. Bachchan has sung one track 'Rozana' composed by Vishal.

He felt that with the audience rapidly maturing in their taste for good cinema, it was high time that filmmakers experimented with creative ideas rather than stick to escapist cinema.

Bachchan said he had no reservations about accepting the role.

''When I read the script, I knew here was nothing to fear,'' he said.

''what is important is to look at the situation which the characters find themselves in. It is what creativity and filmmaking is all about,'' said the Big B.

''Creativity is about imagining what would happen if they find themselves in such a situation. The film is about dwelling into their minds,''he added.

Human beings are complex and it is never that easy to comprehend why people do what they do. Relationships are never as simple as they appear to be, he said.

To a question on whether relationship as shared by his character and newcomer Jiah Khan in the film is justified at the end of the movie, Amitabh said, ''for that you will have to see the entire film.'' To a question on whether he apprehends criticism about doing the film considering the flak he has received for 'Boom' and Sexy Sam character in 'Kabhi Alvida Na Kehna', Amitabh asked, ''Do you think I should not have done Sexy Sam character.

But, it was no frivolous as it was made out to be.'' 'Nishabd' is Ramu's most sensitive story about human relationships. Varma is a responsible director and I have faith in his capabilities,'' said Amitabh.

Varma said he would not have attempted this film had Bachchan not agreed to do the role. ''I used his larger than life image, performing talent and strength in the film. A body ages, feelings do not,'' he added.

When asked why he took the risk of making an unconventional film when his recent films have not done well, said, ''A film is a film and cannot be perceived as a risk before its release.'' Newcomer Jiah Khan said she plays her age in the film. ''My character is of different shades who is extreme in her thoughts.

It was interesting to play such a role,'' she added.

Meanwhile, Red FM presented the music launch of the film and the live preview along with the cast and crew.
