The Station Agent (Tom McCarthy, 2003)

Talk about friendship. The most incongruous threesome (a dwarf train aficionado, a talkative Cuban hotdog vendor, and a middle-aged woman painter who can't get over her son's death) turn out to be the purest of friends. Added to the threesome are a lonely black school girl and a little silly librarian. The center of gravity here is Fin, the dwarf guy, and his deserted train depot. Somewhere in New Jersy. It's surprisingly fresh and heart-warming. The ending is brilliant.
