Continuity: The coins placed on a corpse's eyes towards the end of the film disappear and reappear between shots.
Factual Errors: William Gull says that he is the Royal Family's physician-in-ordinary. In fact, Gull was the Royal Family's physician-in-extraordinary (the original comic book got this right).
Continuity: When Abberline first meets, and discusses the Ripper killings with Sir William Gull, Abberline's drawing of a Liston knife keeps changing shape and position on the blackboard between shots.
Anachronisms: Electric lighting was rare, but not unheard of, in 1888. Even so, the electric light in the library is of a modern design.
Factual Errors: The surgeon Ferral is called "Doctor". In England, surgeons are not (and were not) called "doctor", but "mister".
Miscellaneous: The coachmen's ear is whole in some scenes and it is cut in other scenes
Continuity: Upon arriving at the murder scene (in the back yard of a house), Inspector Abberline's coat and hat are clearly hung upon the fence a moment before we see him actually hang them there.
Anachronisms: There were two lobotomies performed in the movie. The very first lobotomies, which were performed on dogs, didn't occur until 1890, two years after the year of the film. The first human lobotomies weren't performed until later in the 1890s.
Revealing mistakes: During the cemetery scene, the head stone from which the crow flies moves visibly as the bird pushes off.
Anachronisms: Some of the constables and law enforcement officers shown in nighttime scenes are carrying flashlights, which were not patented until ten years after the film's date of 1888.
Anachronisms: The "Ice-pick Lobotomy" method used by the surgeons in the movie, known for its quick and not-so-messy procedure, was invented by Walter Freeman in 1945.
Factual Errors: Jack the Ripper was known to have been left-handed due to stab entry wounds, not right-handed as stated and shown.
Anachronisms: Prince Albert's painting in the gallery declares him to be the Duke of Clarence, a title he would not receive until three years later, in 1891.
