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)
Continuity mistake: In the adult shop, Samantha is dancing in a room and Nino is trying to get her attention so he writes a note for her to see. Between shots his writing on the note changes. (01:37:30)
Continuity mistake: Young Amelie is taking pictures with her camera. The only button on the camera is on the top right. However in the behind shot of her, the button is on the left. (00:06:45)
Continuity mistake: When Amelie sees Nino crouched down by the photo booth, poking around underneath, the plastic bag beside him keeps changing position. (00:21:30)
Continuity mistake: When Nino pulls back the photo booth curtain to reveal the bald "mystery man", the man's toolbox is on the photo booth stool. However, shortly before, we saw the legs and feet of the man standing in the photo booth, and the toolbox was nowhere in sight, and there was nowhere in the booth to hide it. (01:39:00)
Continuity mistake: After Amelie returned the box to the old man. The old man goes to a bar, Amelie is sitting close to him. She drinks 3/4 of her wine. Then the old man asked her "If she ever had kids?" She doesn't answer, but she gulps the same cup of wine, but this time it was full. (00:32:35)
Answer: As far as I can see, Amelie is just trying to give him a view of the world, so he doesn't become entirely cut off.
