The Netflix trailer includes a copyright line with a misprint in the year, it states "Copyright MMXCI", a misprint for MMXVI, which is 2016; MMXCI is 2091. The main film's opening copyright line also has a misprint. It reads "A Netflix Original Film. All rights reserved. MMXVI". This omits the word "Copyright" and the recognized symbol for it. (Copyright is properly asserted at the end of the end credits.)
The narrative of the story says the young bride was brought to the house her husband built for her in 1812, but the dress and hairstyle she is wearing, as a ghost, is from the period of the 1850s to the 1860s. Since she was murdered soon after moving into the house, the dress and hairstyle do not match her backstory.
