To my knowledge, the film "In Search of the Little Flower: The Full Life Story of St. Therese" is the only excellent full-length documentary about St. Therese in English legally available for free viewing on the Internet. It was produced in 2019 by Sancta Familia Media (Brian Timmons and John Patrick Mallon), two devout young Catholic Scotsmen who traveled to France with their pastor, Fr. James Grant, then press secretary to the Bishops' Conference of Scotland, to make the film in order to help the people of Scotland prepare for the historic first visit of the relics of St.Therese to Scotland. From then until 2022, more than 58,000 people have viewed it online. I strongly recommend it. Feast on it!
