She is one of India's most well-regarded and influential film critics and has been at it for more than two decades. Now, Shubhra Gupta has joined the dots between how we watch our movies and live our lives in "50 Films That Changed Bollywood" in the past two decades. "For a long-time film critic, nothing can be more valuable than to be able to look back and assess the changes in the film industry she or he has been covering: Changes across the board, in all areas -- styles of filmmaking, performances, production, distribution and exhibition. "There is also the desire to connect the dots between the films we love most and the kind of audiences we are, and how both impact each other. Writing the book helped me do both things," Gupta, who has been a member of the Central Board of Film Certification (CBFC), told in an interview. She began writing on cinema in the early 1990s "as a lark, filling in for on-leave film reviewers" in the papers that she then worked with. This experience made her realise that she enjoyed it more than anything else and thus began her lifelong tryst with cinema.
