Other mistake: Blood gushed out of the bound man's lower inner arms that were slit with a knife from below the elbow to the wrist (then turned toward the ground). A switch to an aerial view showed no additional blood dripping (while he was still alive). Also, blood would not pour out of his arms to the ground in a horizontal stream like it did. (00:02:04 - 00:02:27)
Factual error: Charlie gives Kaz a flare gun to shoot a shark in the mouth underwater. She manages to fire it underwater and the flare travels several meters. It is impossible for a flare gun to activate underwater. And if the flare was fired into the water it will only travel one or two feet. (01:13:00 - 01:18:00)
Continuity mistake: Before opening the door, the "M" on Eric's letter jacket is on his right lapel but on the left when he enters the room, as well as when he exits. (This is separate from the "M" being on his right lapel but on the left when facing the mirror). (00:40:09)
Revealing mistake: The possessed "Helen" that Fr Daniel threw to the ground by grabbing the back of her hair landed like a stuffed doll, not person. The "body" was mostly padding and the fake "Helen" kind of bounced or teetered after hitting the ground. Also, her arms stayed hidden in front of her whereas a real person would be stretching out or moving arms to try to land as safely as possible. (00:21:35)
Revealing mistake: When Grandpa Paul Rivers (probably a substitute of some kind) was falling (pushed) down the stairs, his body was "floating" and not actually making contact with the steps. (01:33:30)
Factual error: When pit bull Shadow was chasing Phoenix, the distances between them varied - even appearing to increase - but the pit bull should have been able to quickly close the gap and catch Phoenix. In general, an adult person (about 7 mph) cannot outrun a pit bull (25-30 mph). Also, unless Shadow was trained to stop pursuing Phoenix if she got over the fence, pit bulls are actually quite good at climbing fences. (00:02:38)
Other mistake: The way the man fell onto the hood and then the road, landing on his back, after Sami hit him from behind while going fast defies physics. He also landed too far to the left of the driver's side for being hit with the middle of the front bumper. (00:35:41)
Revealing mistake: The blemish/mole that was on the right side of Ghost's nose showed up on her left side (and she was not looking into a mirror). (00:57:40)
Other mistake: The bottle of alcohol (whiskey?) and glass on Morgan's bookcase appear to be the same as the ones the Game Master has in his office; the bottle is emptied to the same level (too similar to be a coincidence). (00:03:23 - 00:06:57)
Continuity mistake: The bull horns and skull attached to the front of Doug's SUV were much larger on his way to the site than when he pulled up to the meeting spot. Initially, the horns spanned past the low beams, but were some distance from the low beams on each side when he arrived. The overall size of the skull was noticeably smaller and looked less menacing. (00:20:03 - 00:20:35)
Continuity mistake: Chris had strands of his bangs hanging down on his forehead but not a second later when the camera panned to a wider view to include all the group of employees. (00:30:44)
Deliberate mistake: The doctor appears to write just three numbers or a short wavy line on the back of his business card for the phone number he told Marjorie to call (to get a second opinion about Nathan). (00:42:35)
Continuity mistake: Sharyn's top sheet was messy and wrinkled underneath her while she was sitting on her bed, but the sheet was smoother and the top part was folded over/down after the doctor left and she returned from pounding on the door. (00:07:26 - 00:08:28)
Continuity mistake: Annie's car's steering wheel is on the left side, but her dashcam showed her on the right side. Both hands appeared to be on/near the steering wheel (not adjusting the dashcam), followed by a brief view of her right hand playing on a keyboard, then returning to Annie who was now on the left side with her left hand on the steering wheel and a cigarette in her right hand. Also, when Annie was on the right side driving, there was no overhead light on above her head, but there was after she moved. (00:15:32 - 00:16:02)
Continuity mistake: When the terrorists take over the plane we see Eightball brutally stab a secret agent to death, and he gets blood on his face and clothing. In many scenes after this the position and amount of blood can be seen changing.
Plot hole: A real estate agent would first ask a prospective home buyer what price range he was interested in and calculate "how much house" he could actually afford to buy before taking him to look at available houses. Austyn took Jim to see multi-million dollar houses, then Jim told her he was "looking in the $250,000 range." Austyn told Jim they could close at $2.5 million and he'd only need 10% down. The 10% down ($250,000) equaled the total amount that Jim wanted to pay for a house. (00:14:03)
Continuity mistake: Before Jen gets on the yacht, Aileen's green halter strap can be seen because the left side of her hair is on or over her shoulder. When Jen gets on board, Aileen's hair is in front, covering up the green strap. The camera shifts when Lewis is hugging Jen and Aileen's green strap is visible again with the left side of her hair behind her. There is no noticeable wind and Eileen is standing in the same place. (00:32:10)
Character mistake: Over the phone, Julie told her sister Sara, " I got them [parents] a bouquet", pronouncing the "T" in bouquet. Bouquet has French origin so the "T" is silent. Bouquet is properly pronounced like bow-kay (American English) or boo-kay (British English). (00:00:55)
