One of the most satisfying movies for a family to watch. You must have seen it, of course, but if you haven't, please do so without further delay.
CWR has a nice little summary and review here.
“You are the ones who are happy; you who remain within the Church by your Faith, who hold firmly to the foundations of the Faith which has come down to you from Apostolic Tradition. And if an execrable jealousy has tried to shake it on a number of occasions, it has not succeeded. They are the ones who have broken away from it in the present crisis. No one, ever, will prevail against your Faith, beloved Brothers. And we believe that God will give us our churches back some day."
-- St. Athanasius
