Amitabh Bachchan is widely regarded as one of the greatest actors in Indian cinema — a living legend whose baritone voice and commanding screen presence defined Bollywood's 'angry young man' era in the 1970s and '80s. With over 200 films across a career spanning more than five decades, he has reinvented himself multiple times, winning four National Film Awards for acting. He is also the beloved long-running host of Kaun Banega Crorepati (India's Who Wants to Be a Millionaire).
