Kareena Kapoor will play the lead role opposite Shah Rukh Khan in Ramgopal Varma’s film, Time Machine. Though Ram Gopal Varma and King Khan were negotiating to do a film together, only now do things seem to have clicked. Kareena and Shah Rukh are also working together in Don, where Kareena has bagged Helen’s role. Kareena is also coming in a Pepsi commercial with Priyanka Chopra and Shah Rukh. Kareena was also supposed to act in Harry Baweja’s Love Story 2050 opposite debutant Harman Baweja. But she recently opted out of the film citing date problems. Speculation is rife that Kareena walked out of Harry’s film to do Varma’s. Kareena will also be seen in Vishal Bharadwaj’s Omkara, besides Subhash Ghai’s 36 China Town.
