Other mistake: Danny (who somehow knows where the Turtles hideout is, maybe someone else in the Foot clan told him) is hiding in the closet, cowering in fear in a corner of it. April, who is way behind and with her view even further obstructed by Leo and the others as she steps to the left, guesses that it is him even if the little guy hasn't spoken a word yet. (01:03:45)

Sammo ★

Other mistake: April mentions that she has not been to the old farmhouse in years, and that the nearest neighbour is four miles away, but the morning of their departure is signaled by a rooster crow. (00:51:00 - 01:01:50)

Sammo ★

Continuity mistake: Master Tatsu is raging against the students, and slams one against the lockers. Another Foot soldier tries to restrain him. The unmasked victim of the assault is clutching the shoulder bit of Tatsu's hood, but his hand is further down his arm in the reverse shot. (00:49:00)

Sammo ★

Continuity mistake: In the rumble inside the antique store, Mike at one point squeals that they could use Raph, "right about now." Cut to Donatello fighting some bad guys to the left of an unimpressed and passive Master Tatsu. The following shot has Don fighting Foot clan members to Tatsu's right, and it's Leonardo to be battling to Tatsu's left (right side of the screen). (00:45:30)

Sammo ★

Continuity mistake: Mike thanks to Don's help does the "Wheel of Fortune, dude!" move; the floor next to him is relatively clear from debris and he sweeps it, but when the bad guy throws a single axe strike next to his head, the floor is all messed up and cut. (00:44:00)

Sammo ★

Revealing mistake: In the middle of the fight inside April's apartment, there's a comedy/action bit with Leonardo repeatedly trying to slash at a Foot Clan soldier. Ultimately, he fools him and kicks him. Behind him, another two bad guys arrive, but there's a very awkward bit in the choreography where one of the guys quite literally does not know where to go and puts himself in a corner with nobody there, stumbling into the other. (00:43:30)

Sammo ★

Continuity mistake: In the rooftop fight, as Raphael quips about the Foot guys studying the abridged version of the Ninja book of fighting, you can see his belt is hanging kinda low, at the hips almost. In the next shot, Raph is fighting with his belt in senior citizen mode, pulled all the way up to 2/3 of the torso. You can tell quite easily because being a turtle his belly is divided in sections. (00:40:45)

Sammo ★

Stupidity: The Foot Clan found the Turtles' hideout in the sewers thanks to one of their members who followed Raphael when he was carrying an unconscious April O'Neil after he saved her from the evil ninjas. When Shredder later is trying to find the Turtles, it takes Danny's betrayal to point him towards April. How stupid does he have to be? It's a connection anyone would have made, it was the second time she was saved, even.

Sammo ★

Other mistake: In a close-up of Chief Sterns' desk as he calls the parents of the juvis, you can see (top right) that Danny's arrest date is 9/3/89, which is inconsistent with the date established at the beginning. (00:28:20)

Sammo ★

Continuity mistake: April is laughing at Mike doing a Rocky impression. Camera behind her shoulder; notice her hand slips off the table. Back to a frontal view, and her hand rests on the table as it was before. (00:26:10)

Sammo ★

Continuity mistake: When April tries to rationalize what she's seeing, says pointing at the Turtles; "And you guys.. " Mike and Leo are looking at her. Leo's arms are low, but in the reverse shot they are held higher towards her. (00:22:25)

Sammo ★

Continuity mistake: When Xander switches off the submarine by tearing off its HD, the flame of the rocket wildly varies in intensity and colors in each shot of the sequence. (01:51:00)

Sammo ★

Stupidity: Gibbons knew a whole day before, with picture evidence, that the bad guy planned to spread the deadly gas using a submarine he had in his basement, but he did nothing as simple as deploying boats, putting barriers on the river, or troops riverside which would have entirely invalidated the Machiavellian plan of the adversary. We see that he and even his subordinate XXX boss the local police around at will and he's able to mobilize the whole Czech aviation at the snap of a finger ordering them to essentially exterminate the entire population of their capital city (!) no questions asked, so surely it was not a problem of having his hands tied by bureaucracy or anything.

Sammo ★

Continuity mistake: Harpoon in hand, Xander yells to his driver "There's a bridge" pointing at a railway bridge with characteristic metal archways. "Cross the bridge!" he orders, and they do cross a bridge that is blatantly different, with no metal structure. (01:46:20)

Sammo ★

Character mistake: When Xander tells Yelena "There must be something we can use", she goes through the manual and reads aloud "Harpoon, gun, parachutes built into seats, ejectable roof." Minutes later, Xander says that they must have missed something, and she says "Weapons, there are more weapons here in the back", and there's the harpoon gun she already read about earlier, she was even on that page of the manual. (01:43:50)

Sammo ★

Continuity mistake: Asia Argento unties Xander with a knife she had strapped to her boots. In close-up, the boots are army-like with a dark olive color, but when she was sitting down, and even better when she later has to put her feet on the car pedals, she is sporting pointy camel-yellow boots. (01:35:30 - 01:45:40)

Sammo ★

Stupidity: Vin Diesel and Asia Argento drive past a few villagers who are totally unfazed by the fact that they just witnessed a potato cart explode in flames with a car sprinting through it. How violent must the Bohemian countryside be for villagers to be so blasé to drive-through pyrotechnics? (01:44:50)

Sammo ★

Continuity mistake: Some potato carts are blocking the road. We see the accident spot and there are several people by the carts taking care of the injured driver, with very few potatoes on the asphalt. When Yelena fires the rockets, no people are by the carts anymore, and as they drive through the flaming wreckage there are many more potatoes - of course since the cart just exploded, but they are all perfectly still and not burnt, not looking at all like they come from a cart that blew up in an inferno of flames a split second before. (01:44:20)

Sammo ★

Continuity mistake: When April naively asks "You guys like pizza?" in front of the manhole, her hand drops in the close-up but is still up and pointing in the wider angle. (00:25:40)

Sammo ★

Revealing mistake: When Darius stomps on the police car with the speedboat, an explosion starts from the bottom of the car just the moment the boat nicks the roof. (00:25:00)
