One day, Keiko (not a villain, but an unsympathetic, helium-voiced child herself) announces she's going away for a few weeks to work. She soon emerges every few months, only to drop off money before taking off again, at one point, for good. Akira forgoes any normal 12-year-old's upbringing (even school) to play mother, father, even Santa Claus to his siblings. There's a trapped feeling in Nobody Knows. For the younger kids, it's the inability to escape to the outside world. For Akira, it's seeing the outside world and knowing he has too many responsibilities to participate in it--when he tries, the results are disastrous. As the children grow up and resources become more scarce, the film's tenacity to show every painful detail of their existence slows the pace to almost a standstill. Still, it's a lovely, haunting tale beset with unforced performances from its young actors, particularly Yagira, who won the best actor prize at Cannes. -- Ellen A. Kim
