Other mistake: The news anchor in the opening scene noticeably flubs her lines at one point.
Continuity mistake: When the mean Santa puts the little girl in his lap and asks her what she wants, she's wearing gloves. When it cuts to a different angle, suddenly her gloves are gone.
Continuity mistake: Celeste's white Honda (Alabama plate #LF8VN3D) is riddled with bullets right after she drives up to the cabin, but there aren't any bullet holes later after the police show up. (01:26:00 - 01:45:00)
Continuity mistake: Throughout the film, John Travolta's hair changes back and forth and back and forth from being really really really short to just really short.
Visible crew/equipment: At the end of the movie when Sparkle is on stage singing in her red dress, a camera shot pans upward toward the ceiling on the stage. There is a cameraman backstage walking on a rafter or something, trying to run so as to not get caught on film, but fails.
Continuity mistake: When Eddie Murphy's assistant makes assumptions about why Jack isn't speaking, he throws his notepad down and has empty hands as Jack pushes him out of the office. When the angle changes, he has a notepad in his right hand.
Continuity mistake: The objects on the desk at Lax's interview with Herman change several times. Sometimes, the tripod is closer to the center of the desk, about a foot away from the file folder, but other times it is closer to where Lax is sitting and one leg is almost touching the folder. The angle of the file folder and distance to the edge of the desk also varies. The Styrofoam cup switches from one side of the desk to the other. (00:17:07 - 00:18:20)
Continuity mistake: When the form falls onto the girl's face, the position of the form changes between shots. (00:00:35)
Plot hole: In this Australian time-travel fantasy, a college student discovers a one-way time portal that allows him to travel one day into the past each time he uses it. While he at first attempts to rescue his girlfriend from a traffic accident that occurred a day earlier, he eventually travels back 50 years (one day at a time) to save his young grandfather. However, in order to go back 50 years (one day at a time), he'd have to repeatedly climb through the portal over 18,000 times. Apparently, it's not an issue, because the movie just glosses right over it in less than a minute.
Visible crew/equipment: When the 2 bad guys get the car you can see the 2 cameramen reflected in the car door. (01:10:00)
Factual error: The movie changes between a basketball season and a playoff basketball game then to a baseball game being played in what looks like early summer...back to a team getting ready for the basketball playoffs. The two seasons don't overlap.
Continuity mistake: When the dog comes in and takes Dale's hand the blonde woman's legs keep changing position. (00:47:00)
Continuity mistake: When the guy with the hat plays pool and goes to hit the blue ball, in the next shot it changes to white and he completely miscues. (00:27:25)
Continuity mistake: Wren is asking her mother about the form for the college loan. When she remarks sarcastically "Afghan citizenship, hello?" she has a big bunch of hair in front of her shoulder, as opposed to the previous shot. (00:02:30)
Factual error: The Iowa is sailing with a depleted crew, one that most likely has no experienced gunner's mates. The 16-inch turret requires a 79-man crew to operate it, and can fire a salvo every 30 seconds. Despite these handicaps, the minimal crew in the movie was firing salvos every few seconds.
Continuity mistake: At the end, the heater is on a chair when Sally chucks the locket on to it. After the spirit has been banished the heater is now on the floor.
Continuity mistake: The German and British airmen are looking at the Northern lights. From the rear the men are apart, but the front shots of them show them much closer to each other.
Continuity mistake: When Sheriff Cooper writes "Karsson" and underlines it on the chalkboard, the way it is written changes between shots. In one particular shot, the line he underlined it with is suddenly rubbed out.
Character mistake: When Michael goes to the antique shop, the sign out front is spelled wrong; it reads "anitques."
Continuity mistake: The alarm clock chimes; Juno Temple reaches up with her left hand, putting it on the upper part of the pillow. Michael Angarano crawls over her to turn the alarm off, but she's napping with her hand by her chin, on the bottom corner of the pillow. (00:02:40)
