Isha Sharvani, who hit the headline for her alleged romance with cricketer Zaheer Khan, was supposed to act with Kamal Haasan in Viswaroopam. The latest buzz is that she has walked out of the project. Says the actress, ; I was very happy when I was approached by Kamal sir s office for a role in their magnum opus. But then, I had to opt out of it because of date issues. I tried my best to accommodate the film, but it s with great regret that I had to pull out of the film. It would have been my dream debut working with a veteran like Kamal. I hope I get to work with him again.
