I saw LION yesterday, about a 5 year old boy in India who is accidentally trapped on a train for 2 days and winds up in place where he can't even speak the language. He is adopted by a couple in Australia and grows up Australian. Then he tries to locate his home in India and heads back, to arrive a foreigner.  It's beautifully shot, with contrasting vistas of India and Australia. Based on a true  story, it reminds me a little of a Vance novel.
