Revealing: In the scene where Raphael and the kid are in the junkyard and the fight breaks out, some of the weapons bend and twist. The staves are supposed to be solid wood.

Continuity: When Keno is trying to join the Foot Clan and is kick boxing with someone, the man in the background who is watching them, to see who is eligible to join, is standing cross-armed. In the next cut his arms are down by his side, and then cross-armed again.

Revealing: In the first fight scene of the film, Keno sweep-kicks one of the bad guys. The man falls over without ever being touched.

Revealing: During the fight sequence between the Turtles and the foot soldiers in the TGRI lab, Michaelangelo has the Ooze when two foot soldiers somersault into view to surround our groovy hero. Watch the foot soldier flipping into the shot in the background. You can see the crash pad he's landing on to help protect the actor.

Revealing: When the turtle Tokka (Rhazar?) jumps in the hole to chase after the turtle brothers, he gets stuck. If you look at his shell, one of the spikes has bent as if the shell is rubber. Seeing as he was a turtle before, the shell should be rock hard.

Revealing: 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.

Continuity: In the end after the Ninjas destroy the bad guy, they fall in some kind of pool. When they come up we can see that they are practically dry.
