There is a series of videos from the 1960s which were brought to my attention. They were presented by Fr. Joseph Dunn and made by a production company called Radharc which he founded. They came to me by way of Fr. John Zuhlsdorf and to him by way of an Irish poster.
Louie Verrechio gave a very good talk on Our Lady of Guadalupe which, although I shall not call a must-watch, certainly is at the very least a should-watch. There is a movie about Our Lady of Guadalue, "The Blood and the Rose", which he cannot recommend highly enough. He thought he knew about the apparition, but after watching the movie he realised just how little he knew.
