Continuity mistake: When the Terminator pulls John off the dirt bike during the drainage ditch chase, the dirt bike falls onto its left side and the gas tank is about to be crushed by the tow truck. The next shot from another angle shows the dirt bike laying on its right side, with the rear tire the first thing to be crushed under the truck. (00:37:30)
Continuity mistake: When the red Sunbird and the Caddy are driving sown the steep hill, the windshield on the Sunbird changes from passenger side busted out, to completely gone, to completely intact, when they hit the tree at the bottom. (01:18:15)
Revealing mistake: There's one scene where they are surrounded by the foot. Leonardo reaches behind him for his katanas, but he doesn't unsheath them. If you look at his elbows, you can see gaps in the pads where the actor in the suit hasn't fully fastened the gloves to the rest of the outfit. (01:05:40)
Revealing mistake: Junior can't get on the Crazy Dance because he is a milimeter too short. After seeing Murph (the 20-year old in his class) and Trixie (on heels) get on it, Junior speeds up the ride and all the kids on it get dizzy and barf everywhere. If you look where the puke shoots out, it's a bit obvious it's not coming from their mouths, but from a point behind them. Most obvious are Trixie and the boy wearing glasses.
Continuity mistake: After making the mud-pie Fred jumps into his box. In the closeup as he lands in it and Elizabeth closes it, you can see Elizabeth has pink trainers on. In the previous and following shots she has white socks on. (01:02:50)
Revealing mistake: When Alice trips and falls on the staircase, the Woman gets on top of her and tries to stab her. Throughout their struggle, you can clearly see that Alice is in fact replaced by a stuntman. (01:28:00)
Continuity mistake: When Clarice tries to push up the blocked door of the self storage container she puts her gloves on her lap. In the next scene the gloves have disappeared. (00:24:15)
Continuity mistake: When Maurice is tossed out of the tavern we get a nice view of the front with its large hanging sign, but after Gaston whispers his plan to LeFou once again we see the front, which is quite different. The sign is gone, and now there are horns hanging on the awning, etc.
Revealing mistake: When Charlie shoots the critter which flies into the air and explodes, we can see the wire the critter is attached to. (01:07:45)
Plot hole: The assassin cuts a hole in the glass to kill the Federation president. But with the size of the hole and the placement of the scope on the phaser rifle, the assassin would not have been able to see out of the hole.
Visible crew/equipment: The boom mic is visible at the top of the screen when J.T. Walsh threatens Barry with the electric chair. (00:51:25)
Continuity mistake: When Sam is talking to the P.I about "Taking care of Max," he gets into his car and the window is up. A few seconds later, the window is down. There wasn't enough time for him to roll it down. (00:54:50)
Visible crew/equipment: When Ricky is shot through the chest, the blood pack is visible bulging through his shirt. (01:28:30)
Other mistake: When Gomez begins to flip through his desk calendar, we see that "today" is Thursday, March 28, 1991. He then turns to the date of the "next quarter". The left hand page shows Thursday, August 8, but the right hand page shows Tuesday, September 9. (00:11:15)
Visible crew/equipment: When they are moving the catapult, if you look above Robin and Azeem, you can see a crew member in the window above them. He is wearing all black, but you can tell he is trying to get out of the shot.
Revealing mistake: When Bill and Ted leave the house with their "bad" selves, Keanu Reeves' double is seen as they move past the camera. (00:21:20)
Revealing mistake: Near the start of the film, when Lt. Harley is watching his love interest show off by doing gymnastics on the tree limbs, several times you can see the actual pole she is swinging on, not the tree limb. (00:08:50)
Continuity mistake: At the start of the quicksand scene, Campanella is carrying his jacket over his shoulder in the initial shot but not in the next one. (01:01:21)
Continuity mistake: Towards the end of the movie, when the mob appraiser has verified the medallions are authentic, he is wearing two white gloves. He then asks if he can leave. When he stands up and gathers his things, he has only one glove on. The shot cuts away. When it cuts back to him, he has two gloves on again. (01:32:50)
Continuity mistake: When Ricky begins walking out of the assistant warden's office after first meeting him, he holds up a photo of his girlfriend and tells him to keep his nose out of his affairs. Some blood can be seen on the back of the photo. In the very next scene, Ricky is shown sitting in his cell looking at the photo, with no blood on the back of it. (00:27:24)
