Continuity mistake: After her dog chases away his goons, Agnes has Carlos hanging upside down with a water hose. The first part, he still has his shirt tightly tucked in his pants. But when she says "Fucking is just not on the menu" his shirt is suddenly out and around his head, his chest exposed. But then it is tucked back in again moments later. (00:44:45)
Continuity mistake: When Carlos is confronting Manny about the Black Forest, the light on Carlos' face keeps changing. The front views show the right side of his face in shadow. But the views from behind and side show the right side of his face is in the light. (00:34:50)
Plot hole: When Gretel is going through the weed maze the first time to find one of Carlos' goons in the cage, Agnes' dog is gone. But just earlier, she told her dog to stay there right by the cage, and the dog did so, and did not leave the garden. Yet Gretel is there and the dog is not seen, nor does it show up or attack her, despite all the loud noise, leaving a trail of Skittles, and the whistling. It does not make any sense that the dog would have vanished and not attacked Gretel. The writing even missed out on a good action scene there.
Continuity mistake: While Agnes has Carlos hanging upside down in her weed garden, she stabs him with a spout to drain blood. The far shot shows her stab him in approximately his stomach area. Then the close up shows it more in his chest closer to his neck. There also appears a bucket underneath him to catch the blood that was not there only moments before. (00:45:00)
Revealing mistake: When Agnes slits Manny's throat, you can see the crease on the prosthetic part of his neck. And the blood flow looks totally fake. (00:37:45)
Continuity mistake: When Hansel and Gretel are first talking to the cops about trying to find Ashton, the girl cop, Hart, has her jacket unzipped. But in the close up when she approaches after seeing how upset Gretel was and said she would go ask the old lady some questions, the jacket is unzipped still but the sides are close together. The shot changes to a side angle as Heart begins to slowly turn around, and suddenly her jacket is open much more. (00:30:40)
Visible crew/equipment: Gretel and her boyfriend Ashton go down to the kitchen to make ginger bread men, but discover they have no more Black Forest weed. So the decision is made that he take off to get more while Gretel stays to make the ginger bread men. There is a metallic fridge behind them and you can see the blurry reflections of them. Ashton takes off and you see his reflection go by and leave as he does. You also see her reflection in it as she is standing still. Then the camera starts to pan to the left. You see a third reflection go by on the fridge, obviously of the camera man. Gretel is supposedly alone in the room. (00:09:20)
Factual error: One of Carlos' henchmen is running from Agnes' dog in her weed garden, in a maze like environment. The actions of the dog are totally unrealistic in how a dog would actually be chasing a person with intent to kill, especially a Doberman. And it was not moving very fast either, like jogging. A real situation like this, the dog would have been full sprint and on the attack, the henchman would not have been able to get away as long as he did as slow as he was going. (00:47:20)
