And it's fifty years since
La Voie Lactée/The Milky Way.
It's probably the first Camino movie that I've seen. By Luis Buñuel, called a dominant international movie director by the NYT when he died in 1983. How many have even heard of him today, let alone seen his movies and this one in particular?
The movie starts with an image of a map of the four roads leading through France to Santiago, accompanied by the voice of a narrator who describes the history of the pilgrimage from its medieval beginnings until now, an "important pilgrimage that still exists today" [in 1969 when the movie was made] and the usual stuff that you read at the beginning of every guidebook today, such as 500,000 pilgrims annually (a claim disputed by many scholars today), from all over Europe, Compostela meaning field of stars (doubtful), the Milky Way being called Saint James Way in many Western languages (true).
The movie was released in movie theatres in many European countries in 1970 such as France, Germany, Benelux, the UK; in Spain only in 1977. I don't know about Italy. It was a bit ... controversial. Two guys walking and hitch-hiking from Paris to Santiago de Compostela. Carrying all their stuff themselves, btw, and not with a lot of money.
