West's horse runs off after the wolf attack at the beginning. Yet, when West, Artie and the new King ride out to see who was sending the Morse code by lantern, West is riding his horse. Then, minutes later, when the Princess screams because there is an animal in the bushes/trees, the animal is ... West's horse. West asks his horse why he ran off.

Some night time scenes were filmed using a filter to darken scenes. BUT this technique leaves the sky blue when in fact the night sky is always black! Further, detail and color (both close and distant) is evident, when in fact it would, should fade, disappear, into the shadows and darkness of the background.
Jim is wearing a coat with snap buttons. BUT the snap button was not invented until 1885 in GERMANY, while the program takes place in the Western US during the Grant administration (1869-1877), SO there is NO overlap there AT all.
The priest conducting the coronation ceremony has a beard typical of an Orthodox priest, but was reading the rite in Latin. Greek is the liturgical language of the Orthodox church, while Roman Catholicism is the largest Croatian denomination.
King Stefan tells West that "Vrkalak" is a "Magyar-Croatian word". There is no such language or language family as "Magyar-Croatian" as the term implies a connection between two languages of different origins. "Magyar" is the native term for Hungarian; Serbo-Croatian is a Slavic language. Hungarian is a member of a language family, related to Finnish, Estonian, Turkish and others, although these relationships are controversial. The phonetic pattern of "Vrkalak" is Slavic and not likely to be of Hungarian origin.
