Amitabh Bachchan is an actor who did DON in the late seventy's. Period. Shahsukh Khan is another actor who has done the new DON. Period. Where's the comparison? Is Shahrukh going on rooftop's claiming his DON is better? Or are the new-DON makers claiming likewise? If there's something called 'patent rights' then that should be taken care of, bas!
