An old picture of an Afghan refugee living in Pakistan has surfaced online, with social media users calling him Amitabh Bachchan's lookalike. "Looks so much like Bollywood superstar Amitabh Bachchan...On a separate note, love the picture!" a user wrote. "You are telling me this is not Amitabh Bachchan?" another user wrote. "Big B's doppelgänger," another comment read.
