Remaking old films has become a trend in Bollywood these days, but actress Vidya Balan believes one should not tamper with an old classic. Apparently, there were reports that the actress was offered to play Sridevi's role in a remake of Sadma, and she turned it down. "I would not do it (remake a film). I can't dare to make or do something again. I was offered remake of Sadma and I said no to it, as I feel one should not touch a film like it, why tamper with it? These are timeless films. One can reinterpret it, but I am not one of those who would go for it," the actress revealed. The Dirty Picture star is busy working on her upcoming film, Tumhari Sulu these days, slated for a release on November 24.
