Revealing mistake: When Mario and Luigi's police car drives off the civilian's car they're stuck to the top, you can blatantly see a metal special effects line that's pulling their car down.

TedStixon

Audio problem: When Mario and Luigi are escaping the police station, after they see the Bob-omb, Mario says, "Goombas! C'mon! Let's go!" and Luigi says, "Look, it was trying to give us that thing!" Their mouth movements don't quite match what they're saying. (Granted, they're facing away from camera for most of the shot, but when their mouths are on camera, you can tell they're not saying that.)

TedStixon

Continuity mistake: After Toad is turned into a Goomba, when Koopa is talking about his own evolution, Toad goes from being shackled to the chair to be unshackled and leaning forward instantly between cuts.

TedStixon

Continuity mistake: When Koopa is explaining the devo chamber to Mario and Luigi, we see a monitor showing an x-ray of Toad's de-evolution. When the camera cuts from the wide shot to the closeup, the monitor has suddenly gone back in the animation and replays the same segment again.

TedStixon

Continuity mistake: When Mario and Luigi are giving their names to the officer, at one point, another officer breaks a glass and we see shards of it landing on the book in front of the officer. A few shots later, most of it has vanished.

TedStixon

Continuity mistake: When Mario and Luigi are giving their names to the officer, there's a woman randomly rubbing her foot against his arm and shoulder throughout the scene. However, the way her foot is on him changes multiple times throughout the scene.

TedStixon

Audio problem: When the officer asks "How many Marios are there between the two of you?" watch closely. In the wide shot for the second half of his line, his mouth is not moving at all.

TedStixon

Revealing mistake: When the old lady falls into the car, she blatantly turns into a dummy for a few shots. (She literally doesn't move at all and is unnaturally stiff.)

TedStixon

Continuity mistake: When Big Bertha picks up the old lady, she goes from holding her in front of her to holding her above her head instantly between cuts.

TedStixon

Audio problem: When Koopa and Lena are introduced, there's a long wide shot of them descending some stairs while Koopa is talking about their master plan. ("I'll be able to merge our world with theirs and get rid of the mammals!", etc.) However, Koopa's mouth blatantly isn't moving at all for most of what he says. He just has an evil grin on his face.

TedStixon

Revealing mistake: When Mario and Luigi first arrive in "Dinohattan" and fall through the railing, you briefly get a clear look at Luigi's stunt-double, who appears to be a bulkier man who looks nothing like John Leguizamo. It goes by quick, so it can be hard to see, but once you notice, it's obvious.

TedStixon

Visible crew/equipment: When Luigi and Mario are chasing after Iggy, Spike and Daisy, during the shot where Mario is talking about "breaking every bone in their body," watch the shadow at the bottom right of the screen. At one point, you can see movement in the shadow from a crew member that got caught in the light.

TedStixon

Audio problem: When Luigi jumps through the portal, as Mario screams "Luigi!", his mouth is not moving at all.

TedStixon

Continuity mistake: When Mario and Luigi are in the cave, Mario goes from Luigi's side to behind, to being on the other side between cuts. There's no point in time where either they (or their feet) aren't on camera, so it makes no sense.

TedStixon

Continuity mistake: When Daisy and Luigi are looking at the fossils, after Luigi says "You're beautiful," the distance between him and Daisy increases instantly as it cuts to a wide shot.

TedStixon

Continuity mistake: When Daisy is showing Luigi the fossils, as the camera cuts from the wide shot to the closeup (when Daisy says "Have a look!"), suddenly their heads go from facing up to facing down between cuts, as do their flashlights.

TedStixon

Revealing mistake: When Daisy takes Luigi to the dig site, there's a long wide shot as they talk and start to head down. As the camera zooms in, you can see the composited background (the bridge, city, etc.) "jiggle" slightly towards the end of the shot where the composite effect didn't quite align up.

TedStixon

Continuity mistake: When Iggy and Spike round the corner and snatch Mario's girlfriend, the look on Iggy's face changes as it cuts from a close-up to a wide shot.

TedStixon

Audio problem: When Iggy and Spike start to follow Mario's truck, they accidentally crash their car. As they drive away, you hear Spike say "Out of my way!" but if you look in the windshield, his mouth isn't moving.

Trivia: One of the first things "Chucky" creator Don Mancini negotiated was to allow Chucky to use harsh profanity, including the word "fuck," as he didn't want to wimp down the franchise for cable. Mancini eventually worked out a deal with the networks, who allowed him up to 10 "fucks" per episode, despite the show airing in the primetime block. Mancini was later able to negotiate a few extra "fucks" in the season one finale.
