I've never been an avid follower of the saints and I'm really only aware of those famous enough to have had movies made about them -- movies like the film Vision about Hildegard of Bingen ...
The lives of other saints, especially founders of religious orders, are more difficult to dramatize, since they often move from dramatic conversion to undramatic administration. It was long rumored that Antonio Banderas (the cousin of a Jesuit) was set to play St. Ignatius of Loyola on screen. But any marketable screenplay would end after the founding of the Society of Jesus. Few moviegoers would want to slog through an hour of Ignatius sitting at his desk composing the Constitutions or writing one of the 6,813 letters he penned during his lifetime.
I don't know, though -- I think a pretty exciting film could be made about Ignatius ...... he was wounded in a battle with the French and could have met (but didn't) the famous Bayard in said battle, he possibly suffered unrequited love of a noble lady, he was thrown into prison by the Spanish Inquisition for being thought an Illuminati, he had a serious mystical experience, he went on pilgrimage to the Holy Land, he went to school (sort of) with John Calvin (and Nicolas Cop?) in Paris, he hung out with the Borgias, and he got into dust-ups with some popes .... the guy led an exciting life! But sadly all we have so far are documentary videos like this one ;) ...
