"Welcome Back" stars John Abraham, Anil Kapoor, Shiney Ahuja and Shruti Haasan, Nana Patekar, Paresh Rawal."We had not thought of making a sequel. But we were getting good response for the film everytime it was played on television. Producers thought it was a good idea to make a sequel they has even registered the title long back," Bazmee said."I took time to come up with a right story. As lot of goodwill was at stake. I don't work in hurry for a film. I take my own time and go ahead only when the script satisfies me," he said.
