Continuity mistake: During the first show, when Mariah Mundi puts the bag over Bizmillar's head, the position of the bag and Bizmillar's hands changes between shots. (00:44:56)
Factual error: Near the end, Zoe and Trey battle to the death, Zoe armed with a tomahawk and a knife, Trey armed with a Husqvarna chainsaw. During the battle, Zoe manages to amputate Trey's right hand, with which he was gripping the chainsaw's safety release and trigger (as his left hand gripped the support handle). Bellowing in pain, Trey continues swinging the chainsaw by its support handle with his left hand. Lo and behold, the chainsaw is somehow, miraculously, still revving in-and-out, which is only possible if the safety release is continuously depressed with the palm of the right hand as the fingers rhythmically flex to squeeze the trigger. Of course, with all major tendons in the wrist severed, an amputated hand cannot grip or flex or squeeze anything.
Plot hole: Luka sneaks into Bayonetta's hotel room and plants a hidden microphone. While sneaking out, he is caught. That's when he is astonished to find a child with Bayonetta who calls her "mummy." He does eventually escape the room and sits in corner with his radio, surprised that they both went to bed and he receives nothing. The problem is: One must be an idiot to plant a mic in a lone woman's hotel room in the dead of the night, unless he truly enjoys listening to her snoring! Planting the mic in her apartment or office, or on her mobile phone makes a lot more sense.
Continuity mistake: When the awful cousin Charlotte hands Gwen the slice of unbirthday cake, she does it with her right hand, left hand, right hand. (00:04:20)
