Revealing mistake: During the escape after the crippling of Berrada, there's a sequence where one of Sofia's dogs gets under her legs and she pets him briefly before launching him to attack one of the bad guys biting him exactly in the crotch. She then shoots him twice in the face putting him out of his misery. Under the person's shirt you can see the squared profile of protective padding. (01:00:00)

Revealing mistake: After shooting Sofia's boss, they are making an escape through a hall with 4 firepits. Sofia orders the dog to attack, and it pounces on a baddie.

Revealing mistake: When John redeems his crucifix "ticket," the crucifix is heated to glowing red and used to brand John between his shoulderblades, signifying that the "ticket" has been redeemed.
