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. When Raphael falls to the ground, his pair of Sai hit the ground but make no noise. There should be a metallic sound against the rooftop.
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.
