SPOILER ALERT! Facts sourced from IMDB trivia and additional research First Movie: Sherlock has a higher IQ than Einstein and Charles Dickens. The five pounds Enola offers 2 boys in the movie to swap clothes with her would equal about 350 pounds today, or 455 USD. Miss Harrison's automobile is a Benz Patent-Motorwagen, produced from 1886-93 and widely regarded as the first production automobile. Mercedes Benz commissioned a set of 100 reproductions in 2002. This is most likely one of those reproductions. Enola consistently "breaks the fourth wall" by turning to face the camera, and speaking directly to the audience. Second Movie Sarah Chapman was a real person, who died in 1945. She led the Match Girls Strike, which was the first-ever industrial action taken by women for women. Both Helena Bonham Carter (Eudoria Holmes) and David Thewlis (Superintendent Grail) have appeared in Harry Potter movies, as Bellatrix Lestrange and Remus Lupin respectively. The mystery Enola investigates reveals that match girls are dying from "typhus" as a result of working with white phosphorous in the matches. This was a real condition, known as phossy jaw. The corrosive nature of the phosphorus they worked with, breathing it in day after day, resulted in first their teeth and then their jawbones slowly decaying. Even once the connection was made it still took decades for the white phosphorus to be banned.
