Emraan Hashmi has penned his son Ayaan’s battle with cancer in his book ‘The Kiss of Life’. While books make some of the most interesting films, Emraan has not really thought of making this one into a Bollywood movie. “I don’t know how it (the book) would lend itself to a movie. I don’t really see it becoming into a feature film with the story that is there. I hope that cinema can go that way and become that kind of film and it gets a mainstream release,” said the actor. However, Emraan is positive to make it into a documentary and spread awareness about cancer and its treatments.
