Factual error: The Robin that comes along in the movie is an American Robin, not a British Robin.
Factual error: At the end of the scene where Bert is a one-man-band, he smashes a cymbal on his forehead at the end of his song. The cymbal could not make any sound as he is holding it with both hands, preventing any vibration.
Factual error: The local police constable wears the divisional letter 'H'. H Division of the Metropolitan Police covered Whitechapel. While it is never specified where the upper middle-class Cherry Tree Lane is, it's certainly not in Whitechapel, which was a solidly working-class district in the heart of the East End. He also wears his letter and number on his helmet plate, a 19th century practice that had been abolished by 1910.
Factual error: When they are up on the roof singing the songs there are faint TV aerials in the distance.
Suggested correction: Nonsense. The sequence is obviously shot on a soundstage with the cityscapes depicted by painted backdrops and matte paintings. Please specify exactly where you saw these supposed aerials.
