Continuity mistake: In the scene where the mother introduces Mason to her college professor, the class ends at 1:35 according to the clock on the wall. In the span of a few seconds as Mason and her mother walk to the front of the classroom the clock shows 1:55.
Suggested correction: The class was not over yet. After the clock showed 1:35 PM, the lecture continued about Pavlov's dogs, (un) conditional response, salivation, and the professor asking the class for another example, etc. The class emptying the room would also take a few minutes. Film time might not have been 20 minutes, but the clock showing 1:55 PM indicated that the class was over at this point. Liv and Mason then went to the front of the room.
I saw 1:38 PM, then class might have been over. It would not take 17 minutes for the classroom to empty (maybe 5 minutes or so). Change your wording to reflect this, and your mistake will be valid.
Continuity mistake: Ben Bart passed away earlier in the film but can be seen dancing on stage with the character Gertrude, at a James Brown concert where he is performing "I Got Soul (Super Bad) ". (01:46:00)
Suggested correction: During that sequence, they intercut James in his gold jumpsuit, with long hanging-down hair, and James in a black-and-white checked vest, doing the same song. In the black-and-white vest era, Ben Bart is still alive, so the dancing could have been from that era.
While that does seem to be the case, it should be pointed out that Ben Bart died in 1968, but the song James Brown is singing, "Super Bad", was recorded in 1970.
Continuity mistake: The sheriff wears his badge over his left side, which is traditional. As he is approaching on horse in the final scene of the movie it is still on his left side. Then for a few seconds in one shot his badge is on the right. (01:23:10)
Continuity mistake: The Judge and son are standing by the side of the road and there's a black bag on the ground between them. When they leave there is no bag on the ground.
Continuity mistake: In the final police chase scene when Lou is getting out of the car to film the car accident, the left hand mirror of his car is intact at first then broken in the next shot.

Continuity mistake: At the Dam Hydro Plant Caesar throws Koba on his back and pummels him. Then they roll once to the right, which now puts Koba on top of Caesar. Yet a quick-cut to their faces shows they kept Caesar on top, still pummeling Koba.
Suggested correction: It's Koba on top of Caesar in the first part of the fight. Caesar gets the advantage after the roll to the right.
Continuity mistake: The scene where Artemisia is seeing Xerxes off into the desert for his transformation is a flipped shot, note the two moles on her forehead. (00:10:30)
Continuity mistake: When they come over the mountain, Moses looks out at the Red Sea and sees nothing on the horizon. When they get across, they can see the mountains where they crossed very easily - the area on other side has mountains similar to the ones they crossed, which should have been visible when first approaching.
Continuity mistake: When Anna Kendrick visits Jennifer Aniston in the hospital it shows a cake from different views. When the views change the candles light and relight. (01:14:30 - 01:15:25)
Suggested correction: The candles on the cake never light and relight. They are always lit from the point when Anna Kendrick (Nina) lights them. In one shot they look unlit due to the pillow behind them but if you look closely they are always lit.
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: 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: 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: 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: 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: 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: 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: 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: 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: 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.
