Before the 1970s, Indian movies mostly featured romantic heroes and focused on light romance. But as time passed, the audience wanted something different. They needed a hero who didn't just accept unfair treatment but stood up and fought back. This is where Amitabh Bachchan stepped in. With his tall frame, deep voice, and intense look, he became the voice of the common man's frustration. This character wasn't just about fighting but was also about a rebellion against a broken system and a struggle for self-respect.
