Continuity mistake: When Nino goes to 'Les deux Moulins' for the first time, we can see Amelie writing the menu on a glass right behind him. A few shots later, we see the glass again and the handwriting is quite different. That's easy to see if you look carefully at the 'd'. Later on, we see the glass once more, and the handwriting has changed again. (01:32:55)
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.
