When Bernard's boat is first pictured, it is headed directly into the rising or setting sun (meaning it's going either due east or due west), yet in the next shot, the sun is over the starboard side of the boat (meaning it's going either north or south).
In the Nazi occupied town the car used by Maeve and Hector to escape comes from a time AFTER the Nazi party was active in Spain. It is a 1949 MG TC roadster. Beautiful by all measure, but a few years early in this show.
