Amitabh Bachchans official entry into Hindi Cinema was in 1969 when he signed Saat Hindustani. It has been 48 years and he rocks still. Amitabh Bachchan was recently in New Delhi at his old college, Kirori Mal where he studied from 1959-62. To raise funds for their auditorium, a huge alumnus from the film industry came forward to pledge support to resurrect the theatre. He donated Rs 51 lakhs to the cause.
