80 people reportedly die from air pollution everyday in the city of Delhi and the issue is certainly of prime importance.Which is why it makes sense that Hollywood actor Leonardo DiCaprio is coming to the city at the end of this month as part of an upcoming documentary film on climate change (yet to be titled) that will “explore the crisis of our time in a way that has never been done before,” as reported by The Indian Express.The mega-star, who became a global superstar with the all-time blockbuster Titanic (1997) in the late '90s and went on to work with directors such as Martin Scorsese and Quentin Tarantino, will be here on October 29, for four days, to profile Sunita Narain of the Centre for Science and Environment. Narain, a Padma Shri awardee, is currently the director general of the CSE, the director of the Society for Environmental Communications, and publisher of the fortnightly environmental magazine, Down To Earth.For latest Hollywood updates follow us on Twitter >>> @TOIEntertain For the latest in Hollywood news, like us on Facebook >>> TOIEntertain For more interesting Hollywood news and pictures follow us on Pinterest>>> timesofindia For latest Hollywood updates follow us on G+ >>> The Times of India Entertainment
