Immigration is the key issue in the latest from The Cooler director Wayne Kramer. Intersecting stories depict the sacrifices made by newcomers living without green cards and those made by the authorities (Sean Penn as a border-patrol agent, Harrison Ford as an immigration officer) who help determine their fate. ''Because it's coming from an emotional point of view and not a political one, there's no grandstanding,'' says Ray Liotta, who plays an applications adjudicator. ''It's not taking one side or the other.''
