This is one great movie, and it always has been.  You follow Richard Dreyfuss' obsession from one stage to the next, even to the loss of his family over it.  You see the events leading up to the grand finale where they pull out all the stops.  It was, is, and ever shall be one of the movies that set the bar for this genre of stories.  It was great then and it's great now.  You won't be sorry you added it to your collection, I gar-on-tee!
