Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.
Continuity mistake: When the real 'manager' comes outside to yell at "Mr. O'Donnell', you see the manager walk back into the club. If you look in the background of the next shot, you can see the manager walking through the door again. (00:13:25)
Continuity mistake: Just after the explosion at the Angels' headquarters, Drew has soot all over her face, but in the final shot of her she's clean. Her hair's a lot neater too. (00:59:20)
Continuity mistake: Toward the end, Russell goes to talk to William at his house. He turns the chair around to sit on it backwards, and throws the shirt down onto the ground. When he sits down the shirt is back on the chair.
Continuity mistake: At the end of the film when Miss Rhode Island is crowned Gracie tries to take the crown from her. Miss Rhode Island beats her with her bouquet of roses. All of the blossoms are knocked off of the stems. A few seconds later when Gracie is fighting Miss Texas the blossoms are back on the roses that Cheryl, Miss Rhode Island is holding. (01:35:00)
Continuity mistake: When the devil is falling apart and his 2nd ear falls off, he tells Nicky he cannot hear him, and asks the demon by his side who catches it to put it back on his head. But towards the end, when the devil is reduced to no more than a mouth and 2 arms, he is able to have a conversation with his demons about what's going on and hear them perfectly. (00:52:05 - 00:58:50)
Continuity mistake: In the tryouts scene, the stripper's top suddenly changes between when she leans in towards Torrance and when she crawls across the table. [This is because in the extended version of the scene, she takes off the top to reveal she is wearing an even more revealing one under the first. Still a mistake, but there's the explanation.]
Continuity mistake: William H. Macy makes dinner plans with the Mayor and writes "Dinner with the Mayor" on the dry erase board in his office. He writes "Dinner w/ the Mayor" in the "Tuesday" slot. Then an intern comes in and accidentally wipes the appointment off the board with her shirt. Macy yells at her and tells her to rewrite the appointment on the board. The whole premise of the joke and pretty big part of the movie is that the intern rewrites the appointment in the wrong day, thereby causing the Hollywood people to miss dinner, enrage the Mayor and his wife and have the town turn on them. When the girl walks away however, the appointment is clearly rewritten in the correct day (Tuesday). This ruins the whole misunderstanding because although the appointment is in the wrong day later in the movie, at the moment the joke is supposed to be set in motion, there is no mistake.
Continuity mistake: During the enactment of the Battle of Zama, Maximus rides his horse around a bend with his sword in his left hand. When we cut to close up, it's back in his right. Looking at the left-handed shot in freeze-frame, you can see the frame has been flipped, left-to-right (check the armor). This was probably for continuity reasons. Similarly, Maximus jumps on the horse and his shoulder protector is clearly on his injured left shoulder. However, a few frames later, the protector is on his right shoulder, then it moves yet again back the correct spot, the left shoulder. (01:24:45)
Continuity mistake: When Daniel is being chased by the Yakuzi in their black Mitsubishi Lancer Evo 6s, one of their Lancers crashes into the tanks. The car used for that crash is however a Lancer Evo 4, which is older than the Evo 6, and has a different front bumper, bonnet and rear spoiler. (01:17:25)
Continuity mistake: In one of the opening scenes when Bob comes in from walking the dog in the rain, he dries the dog off with a towel and puts the towel on top of the coat tree. He tries to feed the dog and when it cuts back to the dog the towel is on the floor, then his wife comes in and the towel is back on the coat tree.
Continuity mistake: When Craig is sitting on Elroy's couch, he lights a joint and puts the lighter on the table. It disappears in the next shot.
Continuity mistake: When Wolverine crashes into the tree knocked over by Sabertooth, notice that the entire front of the truck gets completely folded up and the windshield breaks into a thousand pieces. In the next frame, Wolverine gets thrown through the unbroken windshield and the front of the truck is practically undamaged... (00:18:05)
Continuity mistake: In one scene when Cooper is choreographing the dance, his shirt is sweat-free. The next time you see him there's a big sweat stain on his shirt. (01:05:10)
Continuity mistake: In the third segment of the movie we see Davis, Yolei, Cody and their Digimon playing on the beach. In the wide shot when we see all of them playing we see that Davi's Digimon is in his "rookie" form, Veemon. When they show a closeup of him and Davis together, Veemon is now in his "in training" form DemiVeemon. Then they show them all playing again and he is now Veemon again.
Continuity mistake: When Cage's character offers the money for his brother and the brother is in the car about to get crushed, the back window gets broken out twice. (00:15:55)
