About a week ago, Amy and I watched the Japanese movie Nobody Knows (originally released as Dare mo shiranai), which is based on actual events. Although the movie is sad, there are joyful, inspiring moments scattered throughout the movie. So, if you don't mind watching a long (2 and 1/2 hours) foreign film with subtitles, then you might enjoy Nobody Knows. Anyway, here is a very brief plot summary:
When we first meet the family, the mother and her oldest son Akira are carrying suitcases into a new apartment. When they arrive inside, they open the suitcases and two siblings emerge. (Later, Akira picks up his other sister from the airport.) The mother then informs the children that no one can know that they (i.e. the other siblings) are living in the apartment; therefore, none of the children (except for Akira) are allowed to go outside of the apartment. The movie takes a dramatic change when the mother leaves the children and never returns. The remainder of the movie centers on Akira and his three siblings as they try to stay together even in the face of loneliness, poverty, and death.
