Rakesh Roshan originally envisioned Ajay Devgn alongside SRK, but both actors preferred roles opposite to their typical personas. Iconic roles were finally secured by Shah Rukh and Salman after Aamir Khan declined due to a busy schedule. This revelation comes from Sunaina Roshan’s book ‘To Dad With Love’, highlighting pivotal casting changes that shaped the 1995 blockbuster.
