Vidya Balan is becoming a much sought after star. It is now being reported that Rakesh Roshan's Filmlkraft has signed her up for a role in Krrish 2. Krrish 2, announced in early September this year, will feature Hrithik Roshan in a double role, as the super hero and the super villain! Reports add that Roshan is leaving no stone unturned to make the third part bigger and better than the previous two and will again rope in foreign expertise for dare-devil stunts. If things go as planned then Vidya will be taking over from Preity Zinta ( Koi Mil Gaya ) and Priyanka Chopra ('Krrish'). The film is expected to go on the floors towards the end of 2007.
