Bajo la piel de lobo

There're no spoken words into the 17th minute of the film. There's no monologue till then either.

Several references place the movie in the late 19th century and one reference places it in 1830. It is unlikely that there would be electric light bulbs hanging from the ceilings in a remote village in the Pyrenees in the late 19th century and certainly not in 1830.
