Continuity mistake: When the young girl is on the beach removing her socks, she takes three socks off.
Suggested correction: Jess is wearing yellow socks with polka dots, and yellow wellies. There are three shots in which we see Jess removing or tossing her two yellow polka dot socks, and one of her yellow wellies.
Continuity mistake: During the scene of the first meeting between Gus and Ruby, Krysten Ritter's hair moves back and forth (behind or in front of her left shoulder) between shots multiple times (most obvious example: when he offers her a drink). (00:12:45 - 00:14:35)
Continuity mistake: When Nick is instructed to leave hotel room #700 Chord verbally tells him to "go outside and turn right." but the on-screen arrow points left and we see Nick turn left. (00:29:39)
Revealing mistake: As Glenn, Blake and Monica are being surrounded by zombies, as Monica asks "Fucking hell, how many more of these are there?", in the background you can see a zombie sitting astride his victim, flailing away with a hammer or hatchet. It is obvious that he is just swinging his arm back and forth, without connecting with anything. It looks as if he is dusting, not slaying someone. (01:23:50)
Continuity mistake: Treat Williams is drinking a brown liquid from a glass (scotch?) while accusing Gina Carano of having something to do with his son's disappearance. Shortly afterwards, the liquid is a different color and the glass is much more full. (00:41:40 - 00:42:40)
Plot hole: Tom told I.D. Halden, "My grandmother passed a few years ago and we inherited the family house." If there was a mortgage, who was paying it for a couple years? And if the house was inherited, there would not be a landlord, they would not be paying "rent", and owners do not get served with an eviction notice. (There was no mention of a legitimate reason, such as unpaid taxes.) There's a failure to discern home ownership (with a mortgage) from renting a house (which is not "inherited").
Suggested correction: It seems to be that it is about two different houses, the rented one they already live in, and the inherited one which is renovated.
Continuity mistake: When Paul steals the Camaro, he pulls wires out from under the dash to hot wire it. But after he gets his daughter he suddenly has keys.
Continuity mistake: The students' 3rd game is Kagome with 4 Kokeshi dolls. The pink doll starts to the right of the first student to play, the dolls move in a circle around him, she passes in front of him and by the end of the shot she is near his left. The Kokeshi dolls all move backwards between shots and the pink doll passes in front of the student again. After this, she takes 7 seconds to move about 100° despite nobody slowing down and she took that amount of time to move about 170°.
Revealing mistake: The luminaries lining both sides of the driveway were not lit, although there were a few bags that contained a small circle of dim light that gave the impression of being lit. One of the bags was nonetheless able to catch Boyd's pants leg on fire. (00:11:42)
Continuity mistake: During the early part of the movie, the left rear door of Doc's car is dented. For the rest of the movie, the dent is gone.
Revealing mistake: Crawling through a fire cave you can see propane bottles in the background several times.
Continuity mistake: After David hits Hugh he gets a wound on his mouth which gets smaller the next day.
Continuity mistake: As the jeep with the killer goes over the cliff and smashes face down you can see nobody is in the jeep as it disintegrates the front part. (01:14:00)
Continuity mistake: The appearance/structure of the ground-level components of the well changes several times. In the first view, the unit is mostly gray and rusty with one vertical white pipe. When Ernest is pumping, half of the horizontal pipe is also white and clean. In the rear view, the vertical pipe is brown and rusty. Some mud spurts out of the spigot, but the spigot is clean, dry, and white in the front view. (00:05:10)
Continuity mistake: Roy is on his back at one point, seemingly knocked out. A shot later he's suddenly on his stomach before regaining consciousness.
Continuity mistake: In the beginning, Schapelle checks the boogie bag in in the check-in counter. Then she's seen carrying it over her shoulder. Then a baggage handler takes it away from the check-in counter.
Factual error: The streak ended in '04, but at the beginning of the movie the seniors talking about their last game have letter jackets with the year '05 on the sleeve.
Revealing mistake: At the end the sides of the grave (which Jack just had dug by spade) are too perfect. Only an excavator could get such neat sides.
Visible crew/equipment: Lighting equipment is seen on Trevor's sunglasses just as he finishes speaking in his Mandarin voice. (00:03:30)
Revealing mistake: Most of the tank battle scenes throughout the movie are low budget CGI.
