Continuity mistake: When Kat and the protagonist have dinner, his hands swap between crossed or not depending on the shot. (00:28:32)
Continuity mistake: When they are chasing the 'muncher' ghost down the street, the light bar is only seen flashing on the Ecto 1 when seen from inside the restaurant. The rest of the time they are not on. (00:59:00 - 00:59:30)
Continuity mistake: When Cecilia is talking to Adrian at the dinner table towards the end of the movie, the food on the plate is situated differently from shot to shot as they converse.
Continuity mistake: At the market, Lee picks out five pieces of fruit (one apple and four oranges?), tears a produce bag off, and walks away. He takes a few steps off-screen, and he is next seen going around an end cap and walking down an aisle, with nine pieces of fruit in the produce bag. (00:01:36)
Continuity mistake: A doctor comes into a patient's room. The door swings inward to the right, and it has a heavy lock on it. When she leaves she closes the door. It swings inward, but to the left, and it has no heavy lock. (00:04:10 - 00:08:25)
Continuity mistake: In Millie's Stash House, the first time you see the revolver Guy takes out, it is not cocked. Then, it is cocked. Then, it is not again. Then, it is. Then, not at the time he actually picks it up and cocks it. (00:26:38 - 00:27:02)
Continuity mistake: When the family stopped along the road for a break, the car towing the camper was parked diagonally to the left (not aligned with the camper). The car was visible behind Alan when he was talking to Ben, but it was not when Alan was walking toward Tyler and Charlie. Also, Alan and Ben were at various distances from the camper. (00:13:16 - 00:14:20)
Continuity mistake: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
Continuity mistake: Mara is wearing a white long sleeve jersey when in the Dalton twins' car accident and when Dylan finds her in the water washing off blood. Dylan offers her the gray sweat suit he has in his backpack, but Mara says she isn't wearing it (because they wore those clothes at the police station). When Mara stands up, she has on a dark green T-shirt with a lighter green large circular design on the front. Mara is wearing the green top when she gets to quarantine, as well as later in the movie. This is obviously Mara's top, so where did it come from after she refused to wear the gray sweat suit from Dylan's backpack? (00:33:42 - 00:35:02)
Suggested correction: After rewatching the movie, I noticed that Dylan was POSSIBLY wearing this T-shirt under his jean jacket on his first day of school; the shirts look similar, but little can be seen because it is under the jean jacket. At the same time, Dylan's backpack at the accident scene did not look full enough to contain both parts of the sweatsuit, so it is a stretch to believe the T-shirt was also inside. Moreover, Dylan told Mara that he had a crush on her for two years, so the "old" T-shirt would have just happened to be in this backpack under the sweatsuit worn at the police station. Dylan is thinner than Mara, so it is unlikely that his T-shirt would fit her. When I rewatched the movie, I noticed that the T-shirt in question looked navy blue when Dylan had it on but green when Mara was wearing it.
Continuity mistake: Within a scene, Xanthe's disheveled hair often has a different number of curls/waves (especially on the sides) and the tightness/ looseness varies. Sometimes some strands of curls look like loops sticking out sideways; sometimes her hair looks almost straight on one side. The nature of the curls may vary with front and back views at times. In one scene, she had about three loose waves on the left side of her hair then suddenly it looked almost braided (many waves). (00:07:21 - 00:07:51)
Continuity mistake: Kelly was wearing a white thermal top over a white sleeveless undershirt. After he was thrown into the garbage can, his white thermal top was wet against his back, so he was no longer wearing the undershirt. (00:03:54 - 00:05:43)
Continuity mistake: The direction of the desk lamp's flexible neck varies with the camera's angle. Front views of Rodger show the top of the neck aimed toward the outer edge (length) of the desk and rear views of Rodger show the top of the desk lamp's neck pointed toward him sitting at the desk.
