Continuity mistake: The blood that was on Leonard's right cuff disappeared and re-appeared a couple times. When he was cutting the bloody suit, the blood on his cuff was gone. When Leonard looked into the briefcase, the blood on his right cuff re-appeared, but was no longer there when he was sewing the suit's sleeve (or thereafter). (00:31:38 - 00:32:40)
Continuity mistake: Alan goes into his appointment with Dr. Fredericks at 5:08, and it is still 5:08 on the wall clock when he leaves her office. (00:10:20 - 00:14:03)
Continuity mistake: Solomon put the rope around his waist underneath his coat, but when he was walking through the woods the rope was tied over his coat. Also, the knot would start out in the front of his left side but change to behind his back even though the rope was loose (not taut) behind him. (00:01:55 - 00:02:26)
Continuity mistake: The fruit (tangerines?) in the basket on the table is arranged differently. When the camera is facing Jack, the fruit is of roughly equal heights, evenly spaced around the inner perimeter of the basket but is more uneven and disorderly when facing Everett. Also, the newspaper next to the basket differs, from reaching up to the underside of the handle to more openly fanned and above the handle. (00:40:53)
Continuity mistake: The orange feather toy that was in the cat bed with the cat when Sam got to the bookstore was not there a couple camera shifts later. (00:25:33 - 00:26:25)
Continuity mistake: During the time Sean and Kunle are talking to Bianca after class, Sean is wearing two gold necklaces but only the longer one is showing a few times. (00:04:30 - 00:05:41)
Continuity mistake: When Lee begins walking to the bathroom in the diner and asks her how she feels about sleeping outside, she is in the middle of cutting her pancakes with a knife and fork. When the shot cuts and begins playfully growling with a kid at another table, her right hand has rotated 90°. (00:43:26)
Continuity mistake: When Harry wrapped Lily's ankle injury, there was bloody wrapping below the duct tape. When Karl asked to see Lily's leg, there was no blood showing on the material below the tape. Also, Harry did not completely cover the ankle injury with duct tape like he did to keep creatures from smelling the blood on Lily's stomach cut, questioning why the creatures could not smell the blood on Lily's ankle. (00:19:55 - 00:26:50)
Continuity mistake: At various points throughout the movie, the position of the lamp on the end table (to Charlie's left where he usually sits on the couch) changes, from the base being in the back corner, to mid-way along the chair's arm, to being centered along the rear edge, to near the middle of the table, etc. As the lamp's position changes, the other objects on the table also change. (00:02:15 - 00:04:21)
Suggested correction: "At various points throughout the movie" so he moved his lamp. If the shots aren't consecutive (screenshot, please) this is not a continuity error.
Continuity mistake: Rockit buys a blue (or aqua) surfboard, but it becomes pinkish-purple before turning blue while he surfs. (00:34:00 - 00:44:00)
Continuity mistake: The wall clock, after staying at around 10:12, jumps 4 minutes (to 10:16) in less than 20 seconds. (00:01:05)
Continuity mistake: Kol shouts, "Stop the car!" Adam slams on the brakes from a cruising speed, yet miraculously, the car is bumper-to-bumper with a parked red SUV. When Kol gets back into Adam's car, the red SUV should be visible. However, outside of the windshield, there is a white blur. A car drives close by on a perpendicular road that wasn't there before Adam stopped. (00:15:48 - 00:16:20)
