The Millennium actor and Bollywood superstar Amitabh Bachchan on 15th February clocked 52 years of signing his first film, SAAT HINDUSTANI, and expressed gratitude to his fans for showering him with their love and blessings. The 78-year-old icon began his career with filmmaker Khwaja Ahmad Abbas` action-drama, which he signed on February 15th, 1969. The film released nine months later, on November 7th. Sharing a collage of his pictures, made by a fan, depicting his transformation during the past five decades, Bachchan wrote on Twitter, "It was today that I entered the film industry. February 15, 1969. 52 years! Gratitude." The actor also took to his blog and thanked his fans for making his cinematic journey memorable. Bachchan said had it not been for his "extended family", the milestone would have been "just another day." He wrote "A chapter that the very effective, concerned and loving EF (extended family) remember and portray through their wishes and communications and artistic representations. It is most alluring to see and hear and read what they gift. Had they not, it would have been just another day. One that was spent in the struggle of life.” Post his debut, though Bachchan was praised for his performances in films like ANAND (1971) and 1972 comedy BOMBAY TO GOA , his true rise to stardom happened with Prakash Mehra`s ZANZEER in 1973.
