Factual error: The locomotive of the train that Watson, Holmes, and Toby board early in the movie is a SECR D Class, the first of which came out in 1901. The movie is supposed to be set in 1891, though. (00:20:00)
Factual error: Having run out of coal, Holmes gets the brilliant idea to get fuel from another source. Look at him as he crosses over to the carriage; to the left, you can see an electric line tower, not quite 1891-like. (01:29:45)
Continuity mistake: Von Leinsdorf shoulder-tackles Holmes and nearly makes him fall off the train, but Holmes clings to a railing. He is holding the leftmost section of the railing, but in the reverse shot he's holding the rightmost, and it keeps going back and forth as the angles alternate. (01:39:45)
Sigmund Freud: These are the most intelligent horses in the world, and they have been trained to kill.
