About three minutes in, the CGI train stops on a dime supposedly to allow Marcella to get off. In reality it is impossible for for a train to stop that quickly due to the weight of the train and the laws of physics. It would take hundreds of feet for a train to come to a complete stop.
The film mentions that the action happens in the Chubut Province in 1925.
The Province was created thirty years later; the administrative division name in 1925 was "Chubut National territory"
Some men in the film, particularly the woodcutters, have longish hair and beards. While beards were somewhat out of fashion at the turn of the 20th century, they weren't unheard-of. However, you'd be hard-pressed to find pictures of any European or white North American men with long hair.
