Continuity mistake: In the scene where the town folk are having an outdoor festival, Steven Seagal is invited to play with the band. An older gentleman hands him a guitar with nylon string tuners (open headed classical type) but when he takes it from him, it is a Steel string Martin Acoustic (solid headed flat top) guitar.
Continuity mistake: Pay attention in the beginning of the movie, when Ordell is showing some "girls with guns" to De Niro. While he suggests to run fast the tape, he presses the REWIND key. The expected one would be the FF key. (00:04:25)
Continuity mistake: At the beginning of the movie, when Clark is driving down the street looking at the map, there are 4 kids roller blading in the street. In one shot, one of the kids jumps onto a parkway lawn to avoid being hit by Clark's bad driving. Next shot, when they pan back to the kids, all 4 are still on the street.

Continuity mistake: After eating Paul Sarone, the anaconda has absolutely no lump in its body until it goes to spit him out, and even when it appears, it isn't big enough to be a man. The lump would have been there to begin with, not just magically growing out of nothing.
Continuity mistake: Just before the diner scene, where the two aliens are discussing the galaxy, we see the outside of the Russian restaurant. The neon sign says "haroshaya" meaning "good" all the way across the window, in the next shot inside the restaurant, the "ha", which looks like the English letters "xo", is gone and the sign is centered. (00:41:00)
Continuity mistake: When Ethan Hawke and Uma Thurman are escaping form the party, the sleeve of Ethan's suit is ripped under the armpits when he hits the cop but in a few seconds you see his sleeve completely fixed. (01:11:40)
Continuity mistake: In many places in the movie, a cat noise is heard even though the cat's mouth is quite obviously not open or the cat is licking its face.
Continuity mistake: When Robin Williams puts the flubber into his back pocket to show Sara how it will bounce him back up, you can clearly see a hole in which the flubber escapes. When he falls to the ground and Robin Williams turns over the hole is gone.
Continuity mistake: In one of the scenes Hopkins is trying to make what I think is a fish hook or something. He's obviously been in the wilderness for a while so he's not clean shaven but he isn't exactly beardy either. However, during the scene with this fish hook his beard changes from moderate to bushy to moderate again within seconds.
Continuity mistake: When Howard supposedly has radio sex with that blonde woman, it flashes to other locations where people are listening, including one with police officers standing by early to middle 1990s Ford Crown Victorias. Howard did the stunt in the mid 1980s.
Continuity mistake: At the bachelor party, Kevin Kline has a cigar in his mouth. In one shot, it's whole, the next it's frayed, then in the NEXT, it's whole again.
Continuity mistake: When the police confront Leeloo on the side of the building, she raises her hands and we can see that they're covered in soot. She jumps off and lands in Korben's cab. When she comes to, she presses her hand against the glass, and her hand is magically clean. (00:32:35 - 00:33:20)
Continuity mistake: When Pest leaves the bathroom at the beginning of the movie, you can see a towel wrapped around his waist. The shot goes to a full body shot and you see him whip the towel off. The next shot is of his knees down and the towel is back.
Continuity mistake: As Nicole walks across a plaza with Clooney to meet the Russian spy, she is wearing sheer stockings and low pumps. As she walks off the plaza she is wearing knee high boots with fur tops.
Suggested correction: I think what we see from behind, under the coat is dark trousers and dark low heels.
Continuity mistake: When Clint comes out of the vault, the dead woman's dress is torn badly from the struggle, but when they flash back later, her dress is not torn.
Suggested correction: Later in the woman cop asks why someone would undress, then dress, the body.
Continuity mistake: When Selena is singing "Como La Flor" in Mexico after the crowd was pushing into the stage, her mouth doesn't match the words to the song. Her mouth is a few words ahead of the song.
Continuity mistake: When Robin steps foot into Poison Ivy's lair she is laid out on her flower bed. If you look at the sleeves of her costume, the ends of the sleeves are fringed in a simple leaf like design. Robin spurns Poison Ivy's affections, and an enfuriated Ivy pushes him into the lily pad pool. She is then confronted by Batman, and a soon to arrive Batgirl. Now - look at the huge, obvious, black rubber "thorn" bracelets that suddenly appear on each of her wrists. (01:37:25)
Continuity mistake: J.T.T. is supposedly "getting back" at his brothers by scrubbing their toothbrushes in the toilet. He scrubs the green and yellow brushes quite vigorously inside the toilet bowl. Later on, when the three boys are brushing their teeth, J.T.T. is using one of the brushes that he put in the toilet. (00:03:54 - 00:08:42)
Continuity mistake: When they are driving up the mountain to get to her kids, they cross a river and they get hit on the passenger side of the truck shattering the window, but later when they show them going up the mountain there is a new window there.
