I just found this beautiful, short video of St. Bernadette. This one has many lovely photos of St. Bernadette, and depicts her inner strength and devotion. It ends by saying she is the patron saint of families, and the sick, and those in poverty.
Paramhansa Yogananda was very inspired by a longer movie about her that came out in the 1943, The Song of Bernadette. Wikipedia also has an interesting article on the movie.
