Revealing mistake: Near the end when Ace gets into his Cadillac, in the first shot facing the front of the car, there is a protective glass in front of Ace (the same width as the windshield) with the dashboard in between that glass and the windshield. Note the vertical edge of the glass is visible at the right side, and the rearview mirror's sticker on the windshield casts a shadow onto the second glass. During the stunt, the flames on the dashboard are between the glass shield and the windshield, keeping the actor safe from harm. (02:46:05)
Continuity mistake: When Homer and Bart are on the motorcycle trying to get rid of the bomb, the bomb slips out of Bart's grip. When he's hanging onto his father's shirt, Bart first grips the bomb's handle with his palm and fingers facing the front of the bomb, with the clock. Then when he's hanging onto his father's hair, Bart's hand has flipped around and he's now gripping the bomb's handle with his palm and fingers facing the back of the bomb. Something to look out for is the shot just before the close-up of Chief Wiggum, because as Bart raises his arm the bomb actually flips over in his hand while we're watching. Quite impossible. (01:12:55)
Revealing mistake: In the scene where Doc Brown is following Biff into the tunnel, as Marty starts to pass between the cars on his hoverboard, one of the wheels on the rig supporting the hovering DeLorean is visible. (01:30:30)
Continuity mistake: When Romeo and Juliet are in bed and Romeo playfully pulls the sheet up over his head, his shirt gets caught in the sheet and ends up over his shoulder and around his neck, but in the next shot from the side, his shirt is down.
Continuity mistake: When Elliott gets food for himself and ET he takes the milk container from the top shelf of the fridge, and we see an empty space beside the Skippy peanut butter where the milk had been, but after Elliott drops everything onto the floor, in his next two closeups note the milk container (it has a distinctive curved design) is back on the shelf in the same spot beside the Skippy jar.
Continuity mistake: When Yulaw slams Gabe into a metal box, the glass and debris falls next to his feet. You see both glass and a few chunks of metal, with one especially large chunk of metal. It cuts to Yulaw, then back to Gabe, and now the metal chunks are missing and it just shows glass shards. (01:08:40)
Visible crew/equipment: In the "Battle of Carthage" in the Colosseum, one of the chariots is turned over. Once the dust settles you can see a gas cylinder in the back of the chariot. (01:22:55)
Revealing mistake: If you look at the missing part of the bridge, and look at the shadow underneath, the shadow is of a full bridge. (01:02:35)
Revealing mistake: Bruce Willis wore fake feet during the movie to protect his own while shooting the film. They were like boots that slipped on over his. At the part where the FBI guy shoots at him from the helicopter and Bruce jumps to a lower level of the roof, you can see the tops of the fake feet that aren't tight around his ankles. (01:50:30)
Visible crew/equipment: When Hermione and Harry go back in time, they duck and hide from Malfoy (after being punched) and his friends as they leave. The bulging rectangular outline of the transmitter (for hidden cordless mic) is visible at her lower back, under her pink jacket. It is visible in a few shots, including when they are at the pumpkin patch. The outline of Harry's transmitter is visible at his back, as he bows to Buckbeak at the pumpkin patch, when they rescue him. (01:45:10)
Visible crew/equipment: When Bella pulls up in her truck for her first day at Forks High, as the camera pans from her truck as she parks it into shot, you can see the camera and boom reflected in the triangular window. (00:05:35)
Continuity mistake: In the courtroom scene with King Neptune, Mindy's gold band keeps disappearing and reappearing. (00:13:20 - 00:14:55)
Continuity mistake: When Arnold lets go of the landing gear he lands in the water. A few seconds later we see him walking up towards the beach, and we can now see that he is only wet from his waist down. It's not likely that he would have been able to land standing on his feet and not not becoming completely soaked. (00:24:41)
Continuity mistake: When Tapia is giving the mural artist a dressing-down, his daughter has a book in one hand for most of the scene, but when the shot changes to one from above Tapia and his daughter, the book changes to the other hand. (02:03:15)
Continuity mistake: When Mike is trying to get Mark to ask Stacey out, there is a shot of her behind the counter and Stacey's hair is pulled back on the sides in french braids with ribbons on the ends. Then when Mark approaches Stacey, her hair is pulled back in a clip. The first shot of Stacey with the braid, is actually cut from a scene later in the film, when Mark and Stacey talk at the counter. (00:27:35 - 00:28:20)
Continuity mistake: The tiger bites the seat off the suitor's trousers, allowing the viewer to see his polka-heart boxers. When we see the tiger in the courtyard, he has a part of the same boxer shorts in his mouth. So if he bit off the seat of the trousers, shouldn't he have purple cloth in his mouth? (00:11:45)
Revealing mistake: In the big fight scene at the end, there is a close-up shot of a guard (Sir Mortimer) getting stabbed square in the chest. When the sword is withdrawn, there is obviously no hole in his tunic.
Visible crew/equipment: During the "full attack" at the start of the Battle of Stirling Bridge, Wallace repeatedly shouts, "Hold," and in the wideshot right before Wallace finally shouts, "Now!" as the horses gallop towards the right side of the screen, we can see a white car at the left side of the screen. Viewed widescreen version. (01:27:15)
Revealing mistake: When Bond is in the car following the goons heading into the facility, it shows the techie guy scan a card and then swipe it to open a door. Before he swipes it, the door is already opening. (01:13:15)
Continuity mistake: When William is interviewing Anna in the hotel suite, behind the lever door handles, there are two wide, brass, open lattice finger plates, which change to narrow, brass, closed lattice finger plates. (00:27:30)
