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.
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: In the middle of a sentence, new text appears on the chalkboard behind the speaker, as well as new colouration on a globe behind him. (00:32:42)
Suggested correction: I've changed my mind about this entry. I realise now that these seeming errors are actually intentional, albeit hamfisted, visual manifestations of the changing timeline. I personally think this is a silly way to portray the changing of history due to time travel and the butterfly effect, but who am I to argue with how a fictional construct that seems to defy logic would play out. I'd remove my original entry but I don't see any mechanism to do that.
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 Elizabeth Banks is getting out of Amos' car, when they get back from Bible study, from Banks' angle, you can see that his hand is on the knob on the steering wheel, whereas when the camera changes to Amos' angle, he isn't touching the knob. When the camera changes back to Banks, you can see his hand back on the knob. (00:48:10)
Continuity mistake: The glass that was dropped and shattered on the floor had a different pattern of fragments when Mitch [Robin Williams] knelt to clean it up. Most obvious was that the majority of shattered pieces settled toward Mitch's feet but were on the opposite side of the largest piece of glass during clean-up. There's also a "stupidity" in the way Mitch wiped up the glass - pressing down on the thin towel (apparently to entrap fragments), which is most likely to result in getting pierced. (00:01:40)
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.
Continuity mistake: On the beach, JJ is talking over Kathy when she asks "what pact?" However when he plays back the recording it is just Kathy speaking.
Continuity mistake: Amy set Jim's book perpendicular and very close to the desk's front edge and the pen was diagonal on the book's cover but not close to the desk's edge. When the book came back into view, the pen had been straightened and moved closer to the desk's front edge. (00:36:30)
Continuity mistake: When Michael Keaton goes to his dressing room following the light accident, the note on the flowers changes. It first reads: "They didn't have the whatever you wanted." After he removes his headpiece, the note reads: "THEy didn't have whatever you wanted - SAM."
Continuity mistake: Jay is mopping the floor after promising on the phone to his dad that he'll bring his non-existent fiancee to the wedding. He tries to talk one of the nurses into joining him. While doing so, he stands before her leaning on his mop with his left hand on top, which switches to the right hand between shots. (00:06:40)
Continuity mistake: After David hits Hugh he gets a wound on his mouth which gets smaller the next day.
Continuity mistake: When Kat is asking the detective what he thinks happened to her mother, after Kat is in college and she visits home, the detective lights a cigarette. We see him move the cigarette out of view and when he brings it back there is barely 3 or 4 drags left. The camera cuts to Kat and back at the detective and there's over half of the cigarette left now.
Continuity mistake: The car the hybrid man pushes is in OK shape at first, then he lifts and flips it through the copper fence, and now its whole front side is gone. They might used an already wrecked "car double" for the scene when it crashes and explodes. (01:40:50)
Continuity mistake: As the two assistant workers walk away from the prison building at the end of the first day, Charlotte Gainsbourg's grip on her folders switches between shots.
Continuity mistake: Throughout the film, Nicole Kidman's hair changes color. In one particular dinner scene, her hair is everything from light blonde, to dark blonde, to red.
Continuity mistake: When the woman stands to sing "Bread and Roses", there is a man in a green shirt with a mustache to her left. The camera pans to other miners. When the camera pans back to the original singer, 20 seconds later, the green shirted, mustachioed man is no longer there.
Continuity mistake: Carrie's height changes constantly.
