Making it onto the Guinness World Records list is a matter of pride, and it becomes even more special when you share that achievement with a loved one. Amitabh Bachchan and Abhishek Bachchan have earned a spot in the Guinness Book of World Records as the only real-life father-son duo to have reversed roles on screen. This role reversal between them occurred in the critically acclaimed 2009 film ‘Paa.’ The record is not for many films together as stated here in the post.
