After planning to work together in Munna Bhai MBBS (2003) and failing, Shah Rukh Khan and Rajkumar Hirani are finally collaborating for his next. We hear that veteran actor Dharmendra has been roped in to play SRK’s father in the film also starring Taapsee Pannu. After a long schedule at the Film City, where a Punjab neighbourhood has been recreated, Hirani and his team will head overseas to shoot the movie that deals with immigration.
