Todd Field’s Little Children (A) is a film about unease in modern-day suburbia featuring Kate Winslet and Patrick Wilson as a couple meeting up at the neighborhood swimming pool and having an affair. Meanwhile, a freaky neighbor (Jackie Earle Haley) is possibly on the prowl for his own kind of release in the community. Field once again draws amazing, absorbing performances from his actors and doesn’t give obvious hints about where his plot is headed.
