During Castle's trial, a stenographer is shown typing at a shorthand typewriter, like in American trials. England never has had court stenographers - the judge or magistrate takes notes.
In the trial scene there are journalists taking photographs, this is illegal in UK courts of law. However, at the time the film is set, it was still permitted.
When discussing the original photograph with Beatrice Templeton (Frances Barber), Charles Castle (Toby Stephens) says that the supposed fairy in the image could just be a 'glitch in the emulsion'. The use of the word 'glitch' is anachronistic. Glitch, meaning a small fault, didn't come in to common parlance till the 1960s some 40+ years after the setting of this film.
