Teenage Mutant Ninja Turtles (1990)

Continuity mistake: Michelangelo and Donatello are standing side by each after Shredder introduces himself on the rooftop. But one shot later when Raphael steps in to take on Shredder, Donatello is now behind Michelangelo instead. (01:18:35)

Continuity mistake: Two shots after introducing himself to Raphael, Casey Jones' hockey mask vanishes from its spot on the grass in the background (full screen version). (00:12:15)

Continuity mistake: When Splinter flips Shredder over the edge of the building, Shredder pulls a knife and throws it. When Splinter catches the knife, he catches it with his right hand; in the next shot, Splinter's right hand releases the nunchaku and Shredder falls. The shots are out of order.

Audio problem: While Casey fends off the Foot Clan in the antiques shop, an answering machine falls from April's apartment above, hanging by its power cord. Charles' voice can be heard on the speaker, but after the cord snaps his voice can still be heard finishing a sentence. (00:46:50)

Visible crew/equipment: As April walks from the bathroom trying to get Charles off her case, the top of a camera operator's head is briefly reflected in a mirror above the aquarium. (00:29:50)

Visible crew/equipment: When Michelangelo retracts his head from a sword blow into his shell, you can see a crewman's hands under his armpits, holding and moving his upper arms.

Revealing mistake: During the Turtles fight with Shredder watch carefully, the blade on his left hand bend back, made of rubber.

Continuity mistake: Just after the Turtles train by fighting with each other, Michelangelo is in the barn punching the punching bag. The very next shot is Raphael on top of the barn shouting out Splinter's name. Upon further inspection at the weapon at his side, this is not Raphael. It is Michelangelo. (00:56:45)

Revealing mistake: When Raphael wakes up, and Donatello is laughing, when he opens his mouth, the actor's mouth inside the turtle's mouth. (00:56:25)

Continuity mistake: During the fight in April's apartment, The Foot Clan member swings his weapon at Donatello and misses knocking out the power as seen by sparks which causes the fire. Somehow April's answering machine still works, though.

Continuity mistake: When Raphael angrily leaves and practices his Ninja moves on the roof, he appears on a white building. When he is thrown through the roof down to the other Turtles, it is still a white building. The building in which the Turtles fight The Foot and catches fire is the "Second Time Around Antiques and More" shop where April lives which is brick, not white.

Audio problem: After Leo's failed attempt of fighting Shredder for the first time, Mikey and Donnie then play Rock, Paper, Scissors to see who fights Shredder next. It then cuts to Casey talking to "The Foot" where you can hear Mikey fighting Shredder. The next scene shows all four Turtles in a huddle regrouping, breathing heavy, and out of breath. According to what we heard, Donatello shouldn't be out of breath as he has not fought Shredder for the first time yet.

Continuity mistake: In the beginning, after the Turtles save April, you see her jacket is on correctly as she sits up. A second later, it's off her shoulders.

Continuity mistake: As Casey draws his cricket bat, his bag is empty. A moment later, as he runs off, he has all of his weapons back.

Continuity mistake: In the first meeting with Casey Jones, Raphael jumps over Jones. As he does, Jones starts to turn around. As Raphael lands, Jones is starting to turn around again.

Continuity mistake: After Master Tatsu kicks his opponent in the face, a couple of bystanders in the background instantly move further apart from each other between shots. In addition, one of them is a Foot member who loses his nunchaku as the shot changes. (00:32:30)

Visible crew/equipment: In the rooftop fight sequence with the turtles and Shredder, Raphael jumps over Shredder's head at one point and, here, you can see the crash pad that he lands on (full screen version). (01:20:05)

Continuity mistake: During a fight sequence between the Foot Clan and three of the turtles in April's apartment, keep in mind that April is still tending to an injured Raphael in the living room. But as the floor collapses into an antiques store below, you'll be able to spot her on the lower left side of the screen shielding her eyes from debris - instantly in the store before anyone else (except for Master Tatsu and several other Foot members, who were waiting there to begin with). (00:44:15)

Continuity mistake: After decking Raphael for the Jose Canseco remark, Casey's baseball bat instantly changes hands between shots. (00:12:35)

Visible crew/equipment: When Leonardo takes his first turn attacking Shredder on the rooftop, you can see the raised platform that he leaps from, which gives the effect of a very high jump (full screen version). (01:18:55)
