Indian film actor, perhaps the most popular star in the history of that nation's cinema, known primarily for his roles in action films.

Bachchan, the son of the renowned Hindi poet Harivansh Rai Bachchan, attended Sherwood College in Nainital and the University of Delhi. He worked as a business executive in Calcutta (Kolkata) and performed in theatre before embarking on a film career. Bachchan made his big-screen debut in Saat Hindustani (1969; “Seven Indians”) and achieved his first success with Zanjeer (1973; “Chain”). A string of action films followed, including Deewar (1975; “Wall”), Sholay (1975; “Embers”), and Don (1978). Nicknamed “Big B,” Bachchan personified a new type of action star in Indian films, that of the “angry young man,” rather than the romantic hero. He was often compared to Clint Eastwood (Eastwood, Clint)—although, unlike Eastwood and other American action stars, Bachchan was renowned for his versatility, and many of his roles showcased his talents at singing, dancing, and comedy.

By the end of the 1970s, Bachchan had appeared in more than 35 films and was regarded as India's top film star. His popularity was such that he became something of a cultural phenomenon, drawing large crowds of screaming fans wherever he went. A near-fatal accident on the set of his film Coolie in 1982 touched off a national prayer vigil for his recovery. His subsequent films, however, did poorly at the box office, and Bachchan entered politics at the encouragement of his friend Indian Prime Minister Rajiv Gandhi (Gandhi, Rajiv). In 1984 he was elected to India's parliament by an overwhelming majority, but he resigned his seat in 1989 after being implicated in a bribery scandal that toppled Gandhi's government.

Bachchan returned to film and won the National Award for his portrayal of a mafia don in Agneepath (1990; “Path of Fire”). He later headed Amitabh Bachchan Corporation Ltd., an entertainment venture that specialized in film production and event management. The business was plagued by financial difficulties, however, and Bachchan eventually returned to performing. In 2000 he began hosting the television game show Kaun Banega Crorepati, the Indian version of the U.S. and U.K. hit Who Wants to Be a Millionaire? His easygoing nature and charisma helped make the show one of India's top television programs.
