Factual error: Dickens uses the phrase "On with the motley." which is anachronistically incorrect. The phrase translates from "vesti la giubba", a line of dialogue from the opera 'I Pagliacci'. The opera wasn't written until 1892, and wasn't translated into English until 1902 (by Enrico Caruso).

Factual error: When Rose is locked in the room and the bodies come toward her, you can see a modern-day electric light-switch to the side of the door she's trying to get through. As the Doctor runs down the hall toward her, you can see a central heating radiator. Both are wildly anachronistic for the time period.

Other: At the end, The Doctor and Rose treat Charles Dickens by making the TARDIS dematerialise in front of him. The engines begin to grind but the twin engine pumps do not move.
