Revealing mistake: Running away from the killer, Diana and Chin randomly get attacked by snakes, because why not. You can see in close-ups of Ilenia Pastorelli's face when she screams that there is no trace of the snake wrapped around the neck of the body double in other angles. (01:01:20)
Revealing mistake: Diana is blind and not accustomed yet to her condition; multiple times throughout the movie if she bumps into something she staggers or drops what she is holding - for instance she drops the shopping bags when she bumps into the post meeting Chin. And yet when she is escaping from the police at Chin's house, she bumps into a drying rack and does not even flinch - in fact if you look closely you can see that the actress moved her hand on purpose to hit it cleanly at the proper angle that would make it fold. (00:44:55)
Revealing mistake: Diana's dog breaks free from her captivity with the slightest push against an unlocked pen. (01:15:35)
Revealing mistake: Diana needs to make herself a new DIY cane. She tried to break a few branches, and one eventually makes a snapping sound - you can see though that it just slips into her hand coming from out of the frame. (01:08:00)
Revealing mistake: When inspector Gerry Baldacci gets in the way of the white van (as if there were a single white van in all of Italy), you can see on the asphalt the single distinct tire marks of the perfect size and path from previous takes. (00:43:00)
Revealing mistake: After the accident, some bystanders rush to the car hit by Diana's. A woman leans against the car window spotting a child inside; you can see on the window very conspicuous handprints in that spot from previous takes. (00:17:10)
Revealing mistake: Ispettore Baldacci gets hit by the evil van, and you can see as he flies back from the impact that his face is clean, but in close-up of course all of a sudden his face is a crimson mask. (00:43:05)
