Audio problem: In the opening scene when the band Black Plague is performing, the audio is out of sync and the drums aren't playing what they should be. When playing the cowbell the drummer is hitting the hi-hat, and so on. Also when hitting the snare it's out of sync, Bobby Black is also missing some notes. And when the backing vocals are heard no-one is singing. (00:01:45)
Audio problem: At the climax of the film when the Turtles are about to face Shredder for the first time, Raphael says, "I got him" and then runs to fight.

Audio problem: Near the middle of the movie, in the scene when Van Damme's friend Joshua is taking Helene money, you see that the military police have set up a surveillance across the street.

The window is closed and they are too far away to hear this on a busy street.
