Saroo’s book tells the story of how he was separated from his family as a child, and was later adopted by an Australian family. After growing up in Hobart, he decided to track down his family as an adult, using Google Earth and Facebook, and was reunited with them in 2012 – 25 years after he went missing.

Indian stars Nawazuddin Siddiqui, Priyanka Bose, Tannishtha Chatterjee and Deepti Naval will also join the film’s cast.

Lion, directed by Garth Davis, will start filming in Kolkata, India, before moving to Australia. Nicole’s scenes will take place in Australia around April and May.
