Factual error: Princess Diana died on the morning of 31 August 1997, not 30 August. [Some subtitles say 30th August, some 31st. Can anyone translate the actual French?][The narrator says the 30th]
Continuity mistake: When Amélie goes into the grocer's apartment for the first time, there is a close-up shot of her unlocking the door. The sleeve you see in this shot is completely different from the shirt she's wearing when she steps inside.
Factual error: At the time Amelie's mother dies, little Amelie is about 6/7 years old - you can see her standing in the church just before the tourist falls on her mother. Around the time Amelie leaves the house of her father, she is about 22 years old. However, the narrator speaks of a time-period of five years, which means Amelie would have to be around 15 years old when her mother died.
Other mistake: Amelie only recorded a bit of the Tour de France. When you see it played on the glass man's VCR then there is a bit before she started recording that is being played.
Factual error: When Amelie see the plane crash on TV, that scene was set circa 1980. However, the plane shown was an Airbus A320, which was not introduced until 1987.
Chosen answer: The Glass Man isn't as reclusive as he tells Amelie; he obviously talks to many people and spies on them with his binoculars (he knows all about Amelie's revenge on the grocer and the letter she wrote to Mrs. Wells). It isn't revealed where he got the specific information about Amelie's search for Dominique Bredoteau.
