Thousands of mourners, including Bollywood stars, gathered on Thursday for the funeral of Khanna, braving heavy rains and traffic jams in Mumbai. Known for his shy smile and flamboyant looks, Khanna was often referred to as Bollywood's first real superstar, someone who had a fanatical fan base among women, thanks to the many romantic hits in which he starred during the 1970s. The 69-year-old actor died of an undisclosed illness on Wednesday, plunging his fans into grief and prompting glowing tributes from the Indian film industry.
