LION is the incredible trueย story of why you should never have children in India. Based on Saroo Brierleyโ€™s memoir A Long Way Home, the film, an inspiring drama that earns tears without jerking them, begins with five-year-old Saroo (played by a bouncing ball of energy named Sunny Pawar) becoming separated from his mother and brother and ending up a thousand miles away in Calcutta. He doesnโ€™t know his motherโ€™s name, and he misremembers the name of his hometown. Oh, and they speak Bengali here, not Hindi. Oh, and apparently Calcutta is rife with child-snatchers who prey upon street kids, of which there are tens of thousands.

First-time feature director Garth Davis jangles the nerves with these early scenes, but donโ€™t fret:ย Saroo is rescued soon enough,ย adopted by a saintly Australian couple, John and Sue Brierleyย (David Wenham and Nicole Kidman), who raise him upย lovingly to becomeย Dev Patel. (Patelย gets top billing even though heโ€™s only in the second half of the film. Get a better agent, kids!) Grown-up Saroo, tortured by the knowledge that his family never knew what happened to him, sets out to find them, with only his distant memories and Google Earth to assist him.

Sarooโ€™s path may be unclear, but Lionโ€™s isnโ€™t: Like the train that took him away in the first place, the filmย moves steadily toward its tearfulย destination, propelled by sincere performances andย Volker Bertelmann and Dustin Oโ€™Halloranโ€™s gently urgent musical score. Kidman shows great tenderness as the adoptive mother, underscoring the theme of โ€œfamilyโ€ not being limited by biology, andย Patel is serious-minded and haunted. But itโ€™sย little dynamo Sunny Pawar that youโ€™ll remember best, hisย infectious cheery optimism encapsulating the filmโ€™s hopeful tone.
