The NBC series of the same name, inspired by this film, was ignored, once again, by the Emmys. But it shouldn’t have been, any more than viewers should ignore this original 1989 movie tonight. Steve Martin stars as a parent with almost too much empathy for what his kids are going through. He’s funny, and touching, as are so many members of this deep, talented cast, starting with Jason Robards, Dianne Wiest, Martha Plimpton, Keanu Reeves and Mary Steenburgen. Ron Howard directs.
