Hollywood mulling disaster movie on 2011 Missouri River flood: Tommy Lee Jones as tough-talking Army Corps engineer who sticks finger, then arm, finally head into hole in dike to save nuke plant and adjacent preschool. Leo and Kate reprise their last water-logged work together as plucky farm couple looking gorgeous as they stack sandbags. Alas, Leo comes to familiar end, sinking slowly under river as Celine Dion sings "5 Feet High and Rising."
