Rajini fans angry over Dirty Picture?

The trailer of The Dirty Picture, a biopic on Silk Smita starring Vidya Balan is out and is creating waves across the country. Since Silk Smita was one of the original sex symbols it was not surprising to see Vidya Balan in creations designed to showcase her sex appeal.
Word leaked out that Naseerudin Shah's character portrayed in the trailer as a man who lusts after Silk Smita is inspired from Rajinikanth who has done a few films with the sultry siren back in the day. Rajini's fans of course have been in a fury ever since and are threatening the makers with violence.
The producers are dismissive about such reports saying that the fans are overreacting since Naseerudin plays an ageing star in the film whereas Rajini was in his prime when he worked with Silk Smita.
